These are also called the Upper Limestone Shale, a similar group being found in places below the limestone, and called the Lower Limestone Shale, or, in the north of England, the Tuedian group. Going northward the beds of limestone diminish in thickness, with a proportional increase in the intercalated sandstones and shales, until in Scotland they are entirely subordinate to a mass of coal-bearing strata, which forms the most productive members of the Scotch coalfields.
The Coal Measures, forming the third great member of the Carboniferous series, consist of alternations of shales and sandstones, with beds of coal and nodular ironstones, which together make up a thickness of many thousands of feet - from 12,000 to 14,000 ft.
The areas containing productive coal measures are usually known as coalfields or basins, within which coal occurs in more or less regular beds, also called seams or veins, which can often be followed over a considerable length of country without change of character, although, like all stratified rocks, their continuity may be interrupted by faults or dislocations, also known as slips, hitches, heaves or troubles.
These very thick seams are, however, rarely constant in character for any great distance, being found commonly to degenerate into carbonaceous shales, or to split up into thinner beds by the intercalation of shale bands or partings.
The actual coal measure strata, consisting mainly of shales and clays, are generally impervious to water, but when strata of a permeable character are sunk through, such as the magnesian limestone of the north of England, the Permian sandstones of the central counties, or the chalk and greensand in the north of France and Westphalia, special methods are required in order to pass the water-bearing beds, and to protect the shaft and workings from the influx of water subsequently.
The main level or gate road is driven in the benches coal, or lower part of the seam, while a smaller drift for ventilation, called an air heading, is carried above it in one of the upper beds called the slipper coal.
This is sometimes obviated by holing in the beds below the coal, or in any portion of a seam of inferior quality that may not be worth working.

The lower part of the Keweenawan system consists of a great succession of lava flows, of prodigious thickness.- This portion of the system is overlain by thick beds of sedimentary rock, mostly conglomerate and sandstone, derived from the igneous rocks beneath.
The greatness of the thickness, as it has been measured, is also due in part to the oblique position in which the beds of sediment were originally deposited.
The succession of beds in New York has become a sort of standard with which the system in other parts of the United States has been compared.

The tendency of recent years has been to refer more and more of these beds to the Permian.
The character of some of the conglomerate of the Newark series of the east, and the widespread redness of the beds, so far as it is original, also point to aridity.

The lower and middle parts of the system are but doubtfully represented in the western interior.
If present, they form a part of the Red Beds of that region.
On the Pacific coast marine Jurassic beds reach in from the Pacific to about the same distance as the Triassic system.
In the coastal plain the Comanchean beds are generally not cemented, but consist of gravel, sand and clay, occupying the nearly horizontal position in which they were originally deposited.
In the western interior there is difference of opinion as to whether certain beds rich in reptilian remains (the Morrison, Atlantosaurus, Como, &c.) should be regarded as Jurassic or Comanchean.
In the United States, marine Shastan beds are restricted to the area west of the Sierras, but they here have great thickness.
The distribution of the beds of marine origin shows that the sea crept upon the eastern and southern borders of the continent auring the period, covered the western plains, and formed a great mediterranean sea between the eastern and western lands of the continent, connecting the Gulf of Mexico on the south and the Arctic Ocean on the north.
The Eocene beds are unconformable, generally, upon the Cretaceous, and unconformable beneath the Miocene.
In \Vashington the Eocene is represented by the Puget series of brackish water beds, with an estimated thickness exceeding that of the marine formations of Oregon.
Workable coal beds are distributed through 3000 ft.
The Fort Union stage, when the deposition was widespread about the eastern base of the northern part of the Rocky Mountains, and at some points in Colorado (Telluride formation) and New Mexico (Puerco beds), where volcanic ejecta entered largely into the formation.
This wide range is open to doubt as to the correlation of some of the beds involved.
Marine Pliocene beds are reported to have an altitude of as much as 5000 ft.
The position of these beds is significant of the amount of change which has taken place in the west since the Pliocene period.
The Quaternary beds of lakes Bonneville and Lahontan have been faulted in a small way since they were deposited, and the old shore lines of these lakes have been deformed to the extent of hundreds of feet.
The following sections from selected parts of the country give some idea of the succession of beds in various type regions.
Saluda beds 20* ft.
State Quarry beds 20 40
Geologically the anthracite and bituminous coals mainly belong to the same formation, the Carboniferous, and this is especially true of the better qualities; though it is stated by the United States Geological Survey that the geQlogic age of the coal beds ranges from Carboniferous in the Appalachian and Mississippi Valley provinces to Miocene (Tertiary) on the Pacific coast, and that the quality of the coal varies only to a very uncertain degree with the geologic age.
Finally, of true lignite beds, or of lignite mix d with sub-bituminous qualities, the states of North Dakota, Montana, Texas and South Dakota are credited with deposits of 500,000; 279,500; 23,000; and 10,000 millions of tons respectively.
Round it the Palaeozoic sands and clays, largely derived from its own waste, were deposited as nearly horizontal beds, in many places still almost undisturbed.
The outer ranges in Alberta have usually the form of tilted blocks with a steep cliff towards the north-east and a gentler slope, corresponding to the dip of the beds, towards the south-west.
Roughly speaking, the district consists of a series of parallel ridges, whose summits are depressed into beds or hollows, along which the rivers flow; while between the ridges are low-lying rice lands, interspersed with numerous natural reservoirs.
They may be placed either in separate beds or in the mixed flower border as may be required.
In beds they can be supplemented as the season passes on by the intermixture of later blooming subjects, such as gladioli.
Seeds should be sown in spring in a cold frame, and the young plants should be put out into beds when large enough, and should flower the following May.
All of these rise in the upper part of the Piedmont Plateau, through which they pursue a rapid course over rocky beds, and are navigable only south of the " fall-line," at which and north of which they furnish an abundance of water-power.
The Mary Hitchcock memorial hospital, a cottage hospital of 36 beds, was erected in 1890-1893 by Hiram Hitchcock in memory of his wife.
In the cold regions of the northern lowlands peat occurs in beds of immense thickness.
These beds, with intercalated lavas, form the mountainous west shore of Lough Mask, the east, like that of Lough Corrib, being formed of low Carboniferous Limestone ground.
The district is famous for its salt beds, which are owned and worked by the state, the Laguna Grande alone yielding more than 100,000 tons a year.
The next representatives of the group occur in the Upper Eocene beds of the Fayum district of Egypt, where the genera Saghatherium and Megalohyrax occur.
Among the products are packed meats, flour, beer, trunks, crackers, candy, paint, ice, paste, cigars, clothing, shoes, mattresses, woven wire beds, furniture and overalls; and there are foundries, iron rolling mills and tanneries.
Remains of several of the existing genera have been found in Oligocene and later beds of Europe, Sumatra and North America.
Volcanic rocks are also present but they are not so extensively developed as in the islands of the Javan arc. The Permian beds consist chiefly of limestone and contain numerous fossils similar to those of the middle and upper divisions of the Productus limestone of northern India and the Artinsk stage of the Urals.
Triassic beds with Halobia and Monotis are well-developed in Rotti and appear also to occur in Timor.
Kaolin or China clay is essentially a pure disilicate (Al 2 O 3.2SiO 2.2H 2 O), occurring in large beds almost throughout the world, and containing in its anhydrous state 2 4.4% of the metal, which, however, in common clays is more or less replaced by calcium, magnesium, and the alkalis, the proportion of silica sometimes reaching 70%.
It is a somewhat widely distributed mineral, being met with in Styria, Austria, Hesse, French Guiana, India and Italy; but the most important beds are in the south of France, the north of Ireland, and in Alabama, Georgia and Arkansas in North America.
The French bauxites are of fairly constant composition, containing usually from 58 to 70% of alumina, 3 to 15% of foreign matter, and 27% made up of silica, iron oxide and water in proportions that vary with the colour and the situation of the beds.
An entire skull, obtained from the Lower Pliocene beds of Eppelsheim, Hesse-Darmstadt, in 1836, measured 41ft.
But all routes are difficult, winding between granite and limestone rocks, and abounding in narrow defiles and rugged torrent beds.
About another quarter is utterly barren, consisting of snow-fields, glaciers, bare rock, lakes and the beds of streams. There remains about one-half, which is divided between forest and pasture, and it is the produce of this half which mainly supports the relatively large population.
Some of the older beds indeed are crumpled, but the folding is altogether different in age and in direction from that of the Alps.
The Eastern Alps consist of a central mass of crystalline and schistose rocks flanked on each side by a zone of Mesozoic beds and on the north by an outer band of Tertiary deposits.
Along the line of contact, which is often a fault, the oldest beds of the Molasse crop out, and they are invariably overturned and plunge beneath the Flysch.
A few miles farther north these same beds rise again to the surface at the summit of an anticlinal which runs parallel to the chain.
Beyond this point all signs of folding gradually cease and the beds lie flat and undisturbed.
Eocene beds, indeed, penetrate farther within the chain, but these are limestones with nummulites or lignite-bearing shales and have nothing in common with the Flysch.
In the west it seems to be entirely Eocene, but towards the east intercalated beds with Inoceramus, &c., indicate that it is partly of Cretaceous age.
It bears, indeed, very much the same relation to the Alps that the Siwalik beds of India bear to the Himalayas.
The Mesozoic belt of the Bavarian and Austrian Alps consists mainly of the Trias, Jurassic and Cretaceous beds playing a comparatively subordinate part.
North of the Danube, in Germany as in England, red sandstones, shales and conglomerates predominate, together with beds of gypsum and salt.
Only the Muschelkalk, which does not reach so far as England, and the uppermost beds, the Rhaetic, contain fossils in any abundance.
The Jurassic and Cretaceous beds also differ, though in a less degree, from those of northern Europe.
Tithonian fossils, characteristic of southern Europe, occur in the upper Jurassic, while the Gosau beds, belonging to the upper Cretaceous, contain many of the forms of the Hippuritic sea.
Palaeozoic beds also occur along the northern and southern margins of the crystalline zone.
Jurassic and Cretaceous beds play a larger part than on the northern border, but the Trias still predominates.
Jurassic and Cretaceous beds form the greater part of the Mesozoic band.
They consist chiefly of Jurassic and Triassic beds, but it is the Trias and the Jura of the Eastern Alps and not of Switzerland.
Whence they have come into their present position is by no means clear; but the character of the beds which form them indicates a distant origin.
It consists almost entirely of Jurassic and Cretaceous beds, the Trias in these outer ranges being of very limited extent.
The main chain is formed chiefly of crystalline and schistose rocks, which on the Italian side rise directly from the plain without any intervening zone of Mesozoic beds.
But it is divided longitudinally by a well-marked belt of stratified deposits, known as the zone of the Briangonnais, composed chiefly of Carboniferous, Triassic and Jurassic beds.
This access is especially desirable as regards the store-yards and framing ground, where fermenting manures and tree leaves for making up hot beds, coals or wood for fuel and ingredients for composts, together with flower-pots and the many necessaries of garden culture, have to be accommodated.
Walks are separated from the adjoining beds and borders in a variety of ways.
The central part of the house may be devoted to permanent plants; the side stages and open spaces in the permanent beds should be reserved for the temporary plants.
Heating is effected by means of hot-water pipes below the beds, and against the side ventilators.
The walls bordering the central paths are arched or clotted to admit heat from the chambers below the beds.
Side pipes are occasionally dispensed with, heat being obtained by means of slots at the back of the beds, communicating with the chambers.
The beds are also of use for plunging pot plants.
Pits and frames of various kinds are frequently used for the cultivation of cucumbers and melons, as well as hot beds covered by ordinary garden frames.
They may be supported by iron standards or brick piers, back and front, bearing up a flat bar of iron on which the slates may rest; the use of the bar will give wider intervals between the supports, which will be found convenient for filling and emptying the beds.
A hot-water pipe f should run along both sides of the pathway, close to the front ledge of the lowest beds.
Those intended to provide bottom heat, however, are set in (a) water tanks running under the beds, or (b) in enclosed dry chambers under the beds, or are (c) embedded in the soil or plunging material.
Leaf-mould is eminently suited for the growth of many freegrowing plants, especially when it has been mixed with stable manure and has been subjected to fermentation for the formation of hot beds.
Horse dung is generally the principal ingredient in all hot bed manure; and, in its partially decomposed state, as afforded by exhausted hot beds, it is well adapted for garden use.
After they have ripened in connexion with the parent bulb, the offsets are taken off, stored in appropriate places, and at the proper season planted out in nursery beds.
In favourable situations and seasons some of the very hardiest, as Silene pendula, Saponaria, Nemophila, Gilia, &c., may be sown in September or October, and transplanted to the beds or borders for very early spring flowering.
Brilliant erect-growing caryophyllaceous plants, thriving best in beds of peat earth or of deep sandy loam.
Mussinii, i ft., is a compactly spreading greyishleaved labiate, with lavender-blue flowers, and is sometimes used for bedding or for marginal lines in large compound beds.
Carpet Bedding consists in covering the surface of a bed, or a series of beds forming a design, with close, low-growing plants, in which certain figures are brought out by means of plants of a different habit or having different coloured leaves.
Sometimes, in addition to the carpet or ground colour, individual plants of larger size and handsome appearance are dotted symmetrically over the beds, an arrangement which is very telling.
During the winter season narrow beds are made up of manure, either quite fresh or mixed with old manure, according to the amount of heat required.
These beds are covered with a few inches of the fine old mould obtained from the decayed manure of previous years.
In the early stages seeds of carrots and radishes are sown simultaneously on the same beds, and over them young lettuces that have been raised in advance are planted.
In this way three crops are actually on the same beds at the same time.
Thus with the genial warmth and moisture of the hotbeds, all crops grow rapidly, but the radishes mature first, then the lettuces are taken off in due course, thus leaving the beds to finish up with the carrots by themselves.
Later on in the season, perhaps small cauliflowers will be planted along the margins of the beds where the carrots are growing, and will be developing into larger plants requiring more space by the time all the carrots have been picked and marketed.
As the beds are only about 4z ft.
Fill up with annuals and greenhouse plants those beds from which the bulbs and roots have been raised.
After this season, keep always a reserve of annuals in pots, or planted on beds of thin layers of fibrous matter, so as to be readily transplanted.
Pot strawberries for forcing next winter, and make new beds out of doors as soon as well-rooted runners can be obtained.
Make new strawberry beds if required.
Plant cabbages in beds or close rows till wanted in spring; and cauliflowers in the last week, to receive the protection of frames, or a sheltered situation.
The covering of leaves or litter should be taken off bulbs and tender plants that were covered up for winter, so that the beds can be lightly forked and raked.
Annuals that have been sown in the greenhouse or hotbed may be planted out, and seeds of such sorts as mignonette, sweet alyssum, Phlox Drummondii, portulaca, &c., may be sown in the beds or borders.
The hay or leaf mulching on the strawberry beds should be removed and the ground deeply hoed (if not removed in April in the more forward places), after which it may be placed on again to keep the fruit clean and the ground from drying.
The fruit having now been gathered from strawberry plants, if new beds are to be formed, the system of layering the plants in small pots is the best.
These should be kept cut off close to the old plant, so that the full force of the root is expended in making the " crowns " or fruit buds for next season's crop. If plants are required for new beds, only the required number should be allowed to grow, and these may be layered in pots as recommended in July.
Cover up all beds in which there are hyacinths, tulips and other bulbs with a litter of leaves or straw to the depth of 2 or 3 in.
The stratified rocks of this system include marine limestones, shales and sandstones; estuarine, lagoonal and fresh-water shales, sandstones and marls with beds of coal, oil-bearing rocks, gypsum and salt.
While the continental type of deposit, with its coal beds, was the earliest to be formed in certain areas, and the marine series came on later, in other regions this order was reversed.
Corals, both reef-builders and others, flourished in the clearer waters; rugose forms are represented by Amplexoid, Zaphrentid and Cyathophyllid types, and by Lithostrotion and Phillipsastraea; common tabulate forms are Chaetetes, Chladochonus, Michelinia, &c. Amongst the echinoderms crinoids were the most numerous individually, dense submarine thickets of the long-stemmed kinds appear to have flourished in many places where their remains consolidated into thick beds of rock; prominent genera are Cyathocrinus, Woodocrinus, Actinocrinus; sea-urchins, Archaeocidaris, Palaeechinus, &c., were present; while the curious extinct Blastoids, which included the groups of Pentremitidae and Codasteridae, attained their maximum development.
The fossil plants which are found in the upper beds of the preceding Devonian system are so closely related to those in the Lower Carboniferous, that from a palaeobotanical standpoint the two form one indivisible period.
Frequently a temporary return of marine conditions permitted the entombment of such salt water genera as Lingula, Orbiculoides, Productus in the thin beds known as " marine bands."
The old land area still existed to the north, but doubtless much reduced in height; against this land, detrital deposits still continued to be formed, as in Scotland; while over central Ireland and central and northern England the clearer waters of the sea furnished a suitable home for countless corals, brachiopods and foraminifera and great beds of sea lilies; sponges flourished in many parts of the sea, and their remains contributed largely to the formation of the beds of chert.
The conditions under which the beds of coal were formed will be found described under that head; it will be sufficient to notice here that some coal seams were undoubtedl y formed by jungle or swamplike growths on the site of the deposit, and it is equally true that others were formed by the transport and deposition of vegetable detritus.
In spite of the bulk of the evidence being in favour of geniality of climate, it is necessary to observe that certain deposits have been recognized as glacial; in the culm of the Frankenwald, in the coal basins of central France, and in central England, certain conglomeratic beds have been assigned, somewhat doubtfully, to this origin.
The beds of chert are utilized in the pottery industry, and some of the harder and more crystalline limestones are beautiful marbles, capable of taking a high polish.
All the rivers of this valley, flowing in deep beds of eroded diluvial tuffs, with a fall as much sometimes as 330 to 660 ft.
They probably belong to several geological periods, but all were folded and denuded before the Carboniferous beds were deposited.
These beds are found only in northern Sumatra.
No Permian beds are known, and for many years Mesozoic deposits were supposed to be entirely absent, but Triassic clays and sandstones with Daonella have been found in the upper part of the basin of the Kwalu (East Sumatra).
They rest unconformably upon the Carboniferous beds, and have themselves been tilted to a steep angle.
Cretaceous beds also have been recorded by Backing.
The most valuable coal occurs in the Eocene beds.
The Miocene consists chiefly of marls, with occasional beds of lignite and limestone.
Except in Limburg, where, in the neighbourhood of Maastricht, the upper layers of the chalk are exposed and followed by Oligocene and Miocene beds, the whole of Holland is covered by recent deposits of considerable thickness, beneath which deep borings have revealed the existence of Pliocene beds similar to the " Crags " of East Anglia.
Eastward and westward of Amsterdam, as well as southward, the Pliocene beds rise slowly to the surface, and gradually decrease in thickness.
There is evidence that the sea gradually retreated northwards during the deposition of these beds, until at length the Rhine flowed over to England and entered the sea north of Cromer.
The cost of iron ore is likely to rise much less rapidly than that of coal, because the additions to our known supply are likely to be very much greater in the case of ore than in that of coal, for the reason that, while rich and great iron ore beds may exist anywhere, those of coal are confined chiefly to the Carboniferous formation, a fact which has led to the systematic survey and measurement of this formation in most countries.
Great Britain has many valuable ore beds, some rich in iron, many of them near to beds of coal and to the sea-coast, to canals or to navigable rivers.
The rich beds near Lake Superior, chiefly red haematite, yielding at present about 55% of iron, are thought to contain between II and 2 billion tons, and the red and brown haematites of the southern states about to billion tons.
In Swedish Lapland, near the Arctic circle, are the great Gellivara, Kirunavara and Luossavara magnetite beds, among the largest in Europe.
From these beds, which in some parts are about 300 ft.
There are also important ore beds in the Urals, near the border of Finland, and at the south of Moscow.
The remarkable stability of the mountain appears to be due to the innumerable dikes which penetrate the lava flows and tuff beds in all directions and thus bind the whole mass together.
Westward the chain lies buried beneath the Mesozoic and Tertiary beds of Belgium and the north of France, but it reappears in the west of England and Ireland.
Upon its northern margin lie the nearly undisturbed Cretaceous and Tertiary beds which cover the greater part of Belgium.
The latest beds which are involved in the folds of this mountain range belong to the Coal Measures, and the final elevation must have taken place towards the close of the Carboniferous period.
The fact that in Belgium Jurassic beds are found upon the southern and not upon the northern margin indicates that in this region the chain was still a ridge in Jurassic times.
In the Ardennes the rocks which constitute the ancient mountain chain belong chiefly to the Devonian System, but Cambrian beds rise through the Devonian strata, forming the masses of Rocroi, Stavelot, &c., which appear to have been islands in the Devonian sea.
The Ordovician and Silurian are absent here, and the Devonian rests unconformably upon the Cambrian; but along the northern margin of the Palaeozoic area, Ordovician and Silurian rocks appear, and beds of similar age are also exposed farther north where the rivers have cut through the overlying Tertiary deposits.
Carboniferous beds occur in the north of the Palaeozoic area.
Near Dinant they are folded amongst the Devonian beds, but the most important band runs along the northern border of the Ardennes.
The structure is complicated by a thrust-plane which brings a mass of older beds upon the Coal Measures in the middle of the trough.
Except along the southern border of the Ardennes, and at one or two points in the middle of the Palaeozoic massif, Triassic and Jurassic beds are unknown in Belgium, and the Palaeozoic rocks are directly and unconformably overlaid by Cretaceous and Tertiary deposits.
The Cretaceous beds are not extensive, but the Wealden deposits of Bernissart, with their numerous remains of Iguanodon, and the chalk of the district about the Dutch frontier near Maastricht, with its very late Cretaceous fauna, are of special interest.
Brown coal, or lignite, which appears in the Olkusz district in beds 3 to 7 ft.
There are large beds of hematite some 60 m.
Since the heavy minerals of the cascalho in the river beds are more worn than those of the terraces, it is highly probable that they have been derived by the cutting down of the older river gravels represented by the terraces; and since in both deposits the heavy minerals are more abundant near the heads of the valleys in the plateau, it is also highly probable that both have really been derived from the plateau deposit.
In the latter, especially at Sao Joao da Chapada, the minerals accompanying the diamond are scarcely worn at all; in the terraces and the river beds they are more worn and more abundant; the terraces, therefore, are to be regarded as a first concentration of the plateau material by the old rivers; and the cascalho as a second concentration by the modern rivers.
Africa during the Cretaceous period (after the deposition of the Stormberg beds), and drilled these enormous craters through all the later formations.
But in the " Drift " maps many other types of deposit are indicated, such, for instance, as the ordinary modern alluvium of rivers, and the older river terraces (River-drift of various ages), including gravels, brickearth and loam; old raised sea beaches and blown-sand (Aeolian-drift); the " Head " of Cornwall and Devon, an angular detritus consisting of stones with clay or loam; clay-with-flints, rainwash (landwash), scree and talus; the " Warp," a marine and estuarine silt and clay of the Humber; and also beds of peat and diatomite.
Vesuvius (q.v.), the volcanic forces of which had been slumbering for unknown ages, suddenly burst into violent eruption, which, while it carried devastation all around the beautiful gulf, buried the two cities of Herculaneum and Pompeii under dense beds of cinders and ashes.
In some cases it has even been possible to recover the original arrangement of the garden beds, and to replant them accordingly, thus giving an appropriate framework to the statues, &c. with which the gardens were decorated, and which have been found in situ.
There are pumping works and filtration beds for the water-supply of London.
In bedwork irrigation, which is eminently applicable to level ground, the ground is thrown into beds or ridges.
The next process is the forming of the ground intended for a water-meadow into beds or ridges.
That portion of the ground which is to be watered by one conductor should be made into beds to suit the circumstances of that conductor; that is, instead of the beds over the meadow being all reduced to one common level, they should be formed to suit the different swells in the ground, and, should any of these swells be considerable, it will be necessary to give each side of them its respective conductor.
The beds should run at or nearly at right angles to the line of the conductor.
The breadth of the beds is regulated by the nature of the soil and the supply of water.
Tenacious soils and subsoils, with a small supply of water, require beds as narrow as 30 ft.
Porous soils and a large supply of water may have beds of 40 ft.
The length of the beds is regulated by the supply of water and the fall from the conductor to the main drain.
If the beds fall only in one direction longitudinally, their crowns should be made in the middle; but, should they fall laterally as well as longitudinally, as is usually the case, then the crowns should be made towards the upper sides, more or less according to the lateral slope of the ground.
The beds thus formed should slope in an inclined plane from the conductor to the main drain, that the water may flow equably over them.
The beds are watered by " feeders," that is, channels gradually tapering to the lower extremities, and their crowns cut down, wherever these are placed.
The water overflowing from the feeders down the sides of the beds is received into small drains formed in the furrows between the beds.
For the more equal distribution of the water over the surface of the beds from the conductor and feeders, small masses, such as stones or solid portions of earth or turf fastened with pins, are placed in them, in order to retard the momentum which the water may have acquired.
The descent of the water in the feeders will no doubt necessarily increase in rapidity, but the inclination of the beds and the tapering of the feeders should be so adjusted as to counteract the increasing rapidity.
To effect a remodelling when the ground is in stubble, let it be ploughed up, harrowed, and cleaned as in a summer fallow, the levelling-box employed when required, the stuff from the conductors and main drains spread abroad, and the beds ploughed into shape - all operations that can be performed at little expense.
Let the stript ground then be neatly formed with the spade and barrow, into beds varying in breadth and shape according to the nature of the soil and the dip of the ground - the feeders from the conductor and the small drains to the main drain being formed at the same time.
With a serf population even this was not impossible; but as the beds of the canals were graded to no even slope, it did not follow that if water entered the head it would flow evenly on.
In addition to all these great engineering systems, southern India is covered with minor works of irrigation, some drawn from springs in the sandy beds of rivers, some from the rainfall of 2 sq.
Its haffs fronting the mouths of the large rivers must be regarded as lagoons or extensions of the river beds, not as bays.
Geology.Germany consists of a floor of folded Palaeozoic rocks upon which rest unconformably the comparatively little disturbed beds of the Mesozoic system, while in the North German plain a covering of modern deposits conceals the whole of the older strata from view, excepting some scattered and isolated outcrops of Cretaceous and Tertiary beds.
The Cambrian, for example, is exposed at Leimitz near Hof in the Frankenwald, and the important coal-field of the Saar lies on the southern side of the Hunsruck, while Ordovician and Silurian beds have been found in several localities.
Carboniferous and Devonian beds are also found south-east of the Bohemian massif, where lies the extensive coal-field of Silesia.
The Permian, as in England, is not involved in the folds which have affected the older beds, and in general lies unconformably upon them.
Between the old rocks of the Rhine on the west and the ancient inassif of Bohemia on the east a vast area of Triassic beds extends from Hanover to Basel and from Metz to Bayreuth.
Over the greater part of this region the Triassic beds are free from folding and are nearly horizontal, but faulting is by no means absent, especially along the margins of the Bohemian and Rhenish hills.
The Triassic beds must indeed have covered a large part of these old rock masses, but they have been preserved only where they were faulted down to a lower level.
Along the southern margin of the Triassic area there is a long band of Jurassic beds dipping towards the Danube; and at its eastern extremity this band is continuous with a synclinal of Jurassic beds, running parallel to the western border of the Bohemian massif, but separated from it by a narrow strip of Triassic beds.
Towards the north, in Hanover and Westphalia, the Triassic beds are followed by Jurassic and Cretaceous deposits, the latter being here the more important.
As in the south of England, the lower beds of the Cretaceous are of estuarine origin and the Upper Cretaceous overlaps the Lower, lying in the valley of the Ruhr directly upon the Palaeozoic rocks.
In Saxony also the upper Cretaceous beds rest directly upon the Palaeozoic or Archaean rocks.
Still more to the east, in the province of Silesia, both Jurassic and Cretaceous beds are again met with, but they are to a large extent concealed by the recent accumulations of the great plain.
Ouaternarv beds also cover the floor of the broad deoression throuch which the Rhine meanders from Basel to Mainz, and occupy a large part of the plain of the Danube.
Here there are more, than 6o beds, of a total thickness of 150 to 200 ft.
The thickness of 80 beds amounts to 250 ft., and the total mass of coal is estimated at 45,400 million tons.
Save for beds of lignite, said to exist in the extreme north, coal is not found, and has to be imported, chiefly from the states of Ohio and Pennsylvania, though Nova Scotia furnishes an increasing quantity.
In general, the older beds occur along the northern coast, and progressively newer and newer beds are found towards the south.
Folding, however, has brought some of the older beds to the surface in the hills which lie to the north and north-east of Sciacca.
The Monti Peloritani at the north-eastern extremity of the island consists of gneiss and crystalline schists; but with this exception the whole of Sicily is formed of Mesozoic and later deposits, the Tertiary beds covering by far the greater part.
In both areas they are accompanied by Jurassic, and occasionally by Cretaceous, beds; but of the latter there are only a few small patches.
In the southeastern part of the island there are also a few very small outcrops of Mesozoic beds.
He was wounded and taken prisoner by Antigonus, who pardoned him and appointed him superintendent of the asphalt beds in the Dead Sea.
Sometimes they approach the river in bold promontories, and at others are divided by the dry beds of ancient watercourses.
This deposit varies in thickness, as a rule, from 55 to 70 ft., at which depth it is underlain by a series of coarse and fine yellow quartz sands, with occasional pebbles, or even banks of gravel, while here and there thin beds of clay occur.
Farther east are other canals, of which the most remarkable occupy in part the beds of the Tanitic and Pelusiac branches.
The piles of granite rocks somewhat in the shape of cromlechs which are found scattered about this province, and especially along the western edge of the Hondsrug, have long been named Hunebedden, from a popular superstition that they were "Huns' beds."
Possibly the word originally meant "beds of the dead," or tombs.
In the vicinity are large beds of kaolin, 30 m.
Such beds of salt are found in strata of very varied geological age; the Salt Range of the Punjab, for instance, is probably of Cambrian age, while the famous saltdeposits of Wieliczka, near Cracow, have been referred to the Pliocene period.
In New York it occurs in the Salina beds of the Onondaga series, of Silurian age; and Silurian salt is found also in parts of Michigan and in Ontario, Canada.
Salt often occurs in association with petroleum and natural gas, and extensive beds were discovered in the Wyoming valley in boring for petroleum.
Such casts are not infrequent in the Keuper marls and sandstones, and in the Purbeck beds of England.
In 1779 three beds of rock-salt were discovered at Lawton, separated from one another by layers of indurated clay.
The beds are reached by sinking through the clays and variegated marls typical of this formation.
In the former case it is often difficult to obtain the brine at a density even approaching saturation, and chambers and galleries are sometimes excavated within the saliferous beds to increase the dissolving surface, and water let down fresh is pumped up as brine.
On two sides this area is bordered by belts of folded beds which form on the west the mountain ranges of the Adriatic and Ionian coasts, and on the north the chain of the Balkans.
The core is formed by the mountain masses of Rhodope, Belasitza, Perin and Rila; and here Palaeozoic and Mesozoic beds are absent, and the earliest sedimentary deposits belong to the Tertiary period and lie flat upon the crystalline rocks.
Upon the margins, however, Cretaceous beds are found.
The eastern parts of Greece are composed almost entirely of Cretaceous beds, but nevertheless they must be considered to belong to the central area, for the folds which affect them are nearly at right angles to those of the western chains.
In general, however, the central area is one of faulting rather than of folding, and the sedimentary beds sometimes lie in troughs formed by faults.
In the north, Carboniferous beds are present, and the Trias and the Jura take a considerable part in the formation of the chain.
The Sarmatian beds are also involved in the folds, indicating that the folding was not completed till Pliocene times.
In the south, the older beds disappear and the whole chain is formed chiefly of Cretaceous beds, though Eocene and probably Jurassic rocks are Medit Er R Anean Plutonic Rocks Volcanic Rocks o Active Volcanoes present.
Next follow the Bala Beds, which, with the succeeding Lower and Upper Llandovery shales, sandstones and conglomerates, form the sparsely populated sheepwalks and valleys which occupy most of the north-western part of the county.
The remainder and greater part of the county is occupied chiefly by the gently inclined Old Red Sandstone; in the dissected plateau of the Black Mountains north of Crickhowell the lower marls and cornstones are laid open, while south of Brecon the conglomeratic upper beds form the escarpment and plateaus of the Beacons.
The southern edge of the county is formed by the scarps and moorlands of the Carboniferous Limestone and Millstone Grit (both of which form also the outlier of Pen-ceryg-calch north of Crickhowell), while the lowest beds of the Coal Measures of the South Wales coalfield are reached in the Tawe and Neath valleys (where the beds are much folded) and near Tredegar and Brynmawr.
The sombre colouring is relieved by vegetation along the edges of the nearly flat beds which project like great cornices and serve as nesting-places for sea-fowl.
The Cambrian system - including the Upper (Durness-Eriboll Limestone) and the Lower (Serpulite grit, Fucoid Beds, Quartzite) - forms a narrow band which can be traced for too m.
On the east side of Scotland, where so many fragments of the Secondary rocks occur as boulders in the glacial deposits, a large mass of strata was formerly exposed at Linksfield to the north of Elgin, containing fossils which appear to show it to belong to the Rhaetic beds at the top of the Trias.
The lower part of the Kimmeridge Clay is probably represented by sandstones and conglomerates, forming the highest beds of the series in Sutherland.
They are covered by white sandstones and these by white chalk and manly beds, which represent the Upper Chalk of England.
Occasional beds of tuff are intercalated among these lavas, and likewise seams of fine clay or shale which have preserved the remains of numerous land-plants.
In the immediate vicinity are also extensive beds of iron ore, and this combination of mineral wealth has enabled the town to become a competitor with Essen, Oberhausen, Duisburg and Hagen in the products of the iron industry.
The eastern portion of the district is the ordinary alluvial plain of the Gangetic delta; the western part consists of undulating beds of laterite resting on a rock basis, and covered with small scrub jungle.
Moreover, the calcined matter resembling white sand which covers its sides below the snow-line, extensive beds of lava, and the issue of streams of hot water from its northern side, seem to confirm the deduction that Chimborazo is an extinct volcano.
Most of the country between the Andes and the sea is covered by Tertiary and Quaternary beds; but the range of hills which runs north-west from Guayaquil is formed of Cretaceous and porphyritic rocks similar to those of the Andes.
For instance, in 1880 Whymper found permanent snow on Cotocachi at 14,500 ft., while near by Imbabura was bare to its summit (15,033 ft.); Antisana was permanently covered at 16,000 ft., and near by Sara-Urcu, which is drenched with rains and mists from the Amazon valley all the year round, at 14,000 ft.; Sincholagua had large beds of permanent snow at 15,300 ft., Cotopaxi was permanently covered at 15,500 ft.
The island is composed largely of crystalline and metamorphic rocks, but contains some cretaceous areas which hold extensive beds of coal, especially on the east coast.
The Ionian islands consist almost entirely of Cretaceous and Tertiary beds, but in Corfu Jurassic deposits belonging to various horizons have also been found.
The oldest beds which have yet been recognized are shales and hornstones with Liassic fossils.
The Eocene beds are folded with the Cretaceous, and in many places the two formations have not yet been separately distinguished.
Miocene beds are found in Corfu and Zante, and Pliocene deposits cover much of the low-lying ground.
Other manufactures are railway cars, casks, cooperage, saw and planing mill products, furniture, wooden ware, windmills, gas-engines, and mattresses and wire beds.
The sandstone which lies below the limestone is also, no doubt, of Carboniferous age; but the sandstone above is conformably overlaid by Upper Cretaceous beds and is generally referred to the Lower Cretaceous.
Beneath this Chul formation the older beds of the outer and Turkestan ranges dip and pass to an irregular outcrop near the banks of the Oxus.
The most important feature in this connexion which was noted by the geologist of the RussoAfghan Commission is the existence of vast coal beds in northern Afghanistan.
These beds are conformably succeeded, along the Central Asian watershed, by a continuous series of strata which apparently represent the Permian, Trias and Jurassic of Europe.
They consist of marine beds alternating with freshwater and littoral deposits, together with plant beds and coal-seams of considerable thickness.
The lowest beds of this series, which from their position may belong either to the Permian or to the upper part of the Carboniferous, have yielded no recognizable fossils; but they include a conglomerate which closely resembles the boulder bed near the base of the Talchir series in India.
The Upper Trias has been definitely identified by the occurrence of Halobia and other fossils; while in the higher beds of the series marine forms belonging to the middle and upper Jurassic have been found.
The plant beds occur at several horizons, and among the remains which have been found in them are several forms which occur also in the Gondwana beds of India.
The Jurassic beds are followed, generally with perfect conformity, by the Cretaceous, which covers a large part of Afghan Turkestan and probably forms the greater part of the ranges which run south and south-west from the principal watershed.
The lowest beds consist of red grits which contain Neocomian fossils, while the middle and upper Cretaceous consist chiefly of limestone and chalk.
The entire system may be represented in the west, but in the Herat province and in Afghan Turkestan the middle Cretaceous seems to be absent, and it is probable that, as in other regions, the upper Cretaceous covers a much wider area than the lower beds.
Eocene beds have not yet been proved to exist; but this is probably owing to the imperfect knowledge of the country, for the formation is known in Persia, Baluchistan and the Suliman Hills.
But the most important igneous masses are the great intrusions of syenitic granite and of basic rock which penetrate the Cretaceous beds.
The Gomal involves no passes of any great difficulty, although it is impossible to follow the actual course of the river on account of the narrow defiles which have been cut through the recent conglomerate beds which flank the plains of the Indus.
In the former even the Pliocene beds are crumpled and folded, overfolded and overthrust in the most violent fashion; in the latter none but the oldest beds, certainly none so late as the Permian, have been crumpled or crushed - occasionally they are bent and frequently they are faulted, but the faults, though sometimes of considerable magnitude, are simple dislocations, unaccompanied by any serious disturbance of the strata.
It should, however, be mentioned that in the eastern part of the Himalayas some of the beds resemble those of the Peninsula, and it appears that a part of the old Indian continent has here been involved in the folds of the mountain chain.
There are peat and forest beds, which must have grown quietly at the surface, alternating with deposits of gravel, sand and clay.
Occasionally the Vindhyan beds themselves are strongly folded, as in the east of the Cuddapah basin; but this was the last folding of any violence which has occurred in the Peninsula.
The Vindhyan beds are divided into two groups.
The Vindhyans are well-stratified beds of sandstone and shale, with some limestones.
The total absence of fossils is a remarkable fact, and one for which it is difficult to account, as the beds are for the most part quite unaltered.
The beds are almost entirely of freshwater origin.
The series is mainly confined to the area of country between the Nerbudda and the Sone on the north, and the Kistna on the south; but the western part of this region is in great part covered by newer beds.
The Gondwana beds contain fossils which are of very great interest.
These beds are the result of ice-action, and it is interesting to note that a similar boulder bed is associated with the Glossopterisbearing deposits of Australia, South Africa and probably South America.
The beds there are lower in the series than those of the Raniganj field; they belong to the upper part of the Talchir group, the lowest of the Gondwana series.
The coal-bearing beds cover an area of only about 11 sq.
Cretaceous beds of marine origin are also found in Cutch, Kathiawar and the Nerbudda valley on the northern margin of the Peninsula, and near Pondicherry and Trichinopoly on its southeastern margin.
Water is fairly abundant, though in the dry season obtainable only by digging in the sandy beds of the rivers.
The beds containing Schloenbachia inflata are referable to the Gault.
The minerals found include thick beds of copper at Bembe, and deposits on the M'Brije and the Cuvo and in various places in the southern part of the province; iron at Ociras (on the Lucalla affluent of the Kwanza) and in Bailundo; petroleum and asphalt in Dande and Quinzao; gold in Lombije and Cassinga; and mineral salt in Quissama.
All the rocks are of basalt and greyishtinted lavas, excepting some beds of upraised coral.
They are mostly bordered by dense vegetation; in the dry season water is found in pools in the river beds or can be obtained by digging.
These are overlaid by a limestone, upon which rests conformably a series of sandstones with coal seams. The age of these beds is unknown.
The coral beds of Mindanao and the Sulu Archipelago are of unsurpassed beauty, and Guimaras, Cebu and Siquijor are completely covered with a thick cap of coral limestone.
Mats, rugs and carpets are made principally of split bamboo; chairs and beds of balinag and other woods and of rattan.
Solutrian "finds" have been also made in the caves of Les Eyzies and Laugerie Haute, and in the Lower Beds of Cresswell Cave (Derbyshire).
Ail the larger rivers, except the Gumti, as well as most of the smaller streams, have beds hardly sunk below the general level; and in time of floods they burst through their banks and carve out new channels.
Numerous shallow ponds or jhils mark the former beds of the shifting rivers.
Carboniferous beds, consisting chiefly of slates, sandstones and conglomerates, are found in the south-eastern provinces.
In San Diego, Imperial and Riverside counties a number of creeks or so-called rivers, with beds that are normally dry, flow centrally toward the desert of Salton Sink or " Sea "; this is the lowest part of a large area that is depressed below the level of the sea, - at Salton 263 ft., and 275 ft.
In the extreme north at the Cock of Arran, there is a small development of these beds; they also occupy the whole of the east coast south of Corrie, and they spread over the south part of the island south of a line between Brodick Bay and Machrie Bay on the west.
The fossils from the Rhaetic beds belong to the Avicula contorta zone, those from the Lias to the Ammonites angulatus zone, while the blocks of limestone with chert contain Inoceramus, Cretaceous foraminifera and other organisms. The materials yielding these fossils are embedded in a course volcanic agglomerate which gives rise to crags and is pierced by acid and basic igneous ricks.
The plains sediments contain important coal beds, which are worked in nearly every county in the state.
All these beds are much disturbed and folded.
The low-lying country between the mountain ranges is covered for the most part by Tertiary and Quaternary deposits, but Cretaceous beds occur at several localities.
The Cretaceous beds, which have long been known in west Borneo, are comparatively little disturbed.
Cretaceous beds of somewhat later date are - found in the Marpapura district in south-east Borneo.
The Tertiary beds generally lie nearly horizontal and form the lower hills, but in the Madi plateau and the Schwaner range they rise to a height of several thousand feet.
Salter, the palaeontologist; and in 1852 he included the Llandeilo and Bala beds (Silurian) in the Upper Cambrian.
Nevertheless, from 1851 to 1855, Sedgwick, in his writings on the British palaeozoic deposits, insisted on the independence of the Cambrian system, and though Murchison had pushed his Silurian system downward in the series of rocks, Sedgwick adhered to the original grouping of his Cambrian system, and even proposed to limit the Silurian to the Ludlow and Wenlock beds with the May Hill Sandstone at the base.
A similar deposit occurs in the Gaisa beds near the Varanger Fjord in Norway.
An uppermost series lies above the Olenus fauna in some areas; it is represented by the Tremadoc beds in Britain or by the Dictyonema beds or Euloma-Niobe fauna elsewhere.
In the lower series are, in descending order, the "Serpulite grits" or "Salterclla beds," the "Fucoid beds" and the "Eriboll quartzite," which is divided into an upper "Pipe rock" and lower "Basal quartzite."
The Cambrian rocks of Ireland, a great series of purple and green shales, slates and grits with beds of quartzite, have not yet yielded sufficient fossil evidence to permit of a correlation with the Welsh rocks, and possibly some parts of the series may be transferred in the future to the overlying Ordovician.
In Russian Poland is a series of conglomerates, quartzites and shales; some of the beds yield a Paradoxides fauna.
