Towards the end of the period, however, during the deposition of the Portlandian beds, the sea again retreated, and in the early part of the Cretaceous period was limited (in France) to the catchment basins of the Sane and Rhnein the Paris basin the contemporaneous deposits were chiefly estuarine and were confined to the northern and eastern rim.
The climate is healthy in the uplands, though subject to violent changes; in the valleys fever is very prevalent, especially in the basins of the Boyana, the lower Drin and the Simen.
When the attempt was made to mark this boundary the commissioners were unable to agree on a line across the Puna de Atacama in the north, where parallel ranges enclosing a high arid plateau without any clearly defined drainage to the Atlantic or Pacific, gave an opportunity for conflicting claims. In the south the broken character of the Cordillera, pierced in places by large rivers flowing into the Pacific and having their upper drainage basins on the eastern side of the line of highest crests, gave rise to unforeseen and very difficult questions.
The elevated plateaus between these ranges are semiarid and inhospitable, and are covered with extensive saline basins, which become lagoons in the wet season and morasses or dry saltpans in the dry season.
The basin of the Garonne occupies south-western France with the exception of the tracts covered by the secondary basins of the Adour, the Aude, the Hrault, the Orb and other smaller rivers, and the lowlying plain of the Landes, which is watered by numerous coast rivers, notably by the Leyre.

The department of Meurthe-et-Moselle (basins of Nancy and Longwy-Briey) furnished 84% of the total output during the quinquennial period 1901-1905, may be reckoned as one of the principal iron-producing regions of the world.
The mountains both in Victoria and New South Wales were snow-capped, and glaciers flowed down their flanks and laid down Carboniferous glacial deposits, which are still preserved in basins that flank the mountain ranges, such as the famous conglomerates of Bacchus Marsh, Heathcote and the Loddon valley in Victoria, and cf Branxton and other localities in New South Wales.
They are also preserved in basins on the western plateau, as shown by brown coal deposits passed through in the Lake Phillipson bore.

The rivers of the province belong to the basins of the Indian Ocean and the Java Sea respectively, the water-parting being formed by the western and eastern ends respectively of the northern and southern lines of mountain peaks.
The communication between the Atlantic and Arctic basins being cut off, as already described, at a depth of about 300 fathoms, the temperatures in the Norwegian Sea below that level are essentially Arctic, usually below the freezing-point of fresh water, except where the distribution is modified by the surface circulation.
Before that time there was no basin or wet-dock, though the river Medway to some extent answered the same purpose, but a portion of the adjoining salt-marshes was then taken in, and three basins have been constructed, communicating with each other by means of large locks, so that ships can pass from the bend of the Medway at Gillingham to that at Upnor.
The Aegean itself is naturally divided by the island-chains and the ridges from which they rise into a series of basins or troughs, the deepest of which is that in the north, extending from the coast of Thessaly to the Gulf of Saros, and demarcated southward by the Northern Sporades, Lemnos, Imbros and the peninsula of Gallipoli.
South of this the country between the frontier of Tuscany and the Tiber is in great part of volcanic origin, forming hills with distinct crater-shaped basins, in several instances occupied by small lakes (the Lake of Bolsena, Lake of Vico and Lake of Bracciano).
The furrows are the great ocean basins, and these would still persist even if the land surface were enlarged to the 1400 fathoms contour.
Rivers bring down the plants of the upper levels of their basins to the lower: thus species characteristic of the chalk are found on the banks of the Thames near London.
The " tetrahedral theory " brought forward by Lowthian Green,' that the form of the earth is a spheroid based on a regular tetrahedron, is more serviceable, because it accounts for three very interesting facts of the terrestrial plan - (1) the antipodal position of continents and ocean basins; (2) the tri angular outline of the continents; and (3) the excess of sea in the southern hemisphere.
These basins of internal drainage are calculated to amount to 22% of the land surface.
Differences in land forms do not exert great influence on the distribution of living creatures directly, but indirectly such land forms as mountain ranges and internal drainage basins are very potent through their action on soil and climate.
The filtering works include 6 lime saturators, 2 mixing or softening tanks, 6 settling basins, 10 mechanical filters and 2 clear-water reservoirs.
Prominent among them, and dwelling in the division occupied by the Celts, were the Helvetii, the Sequani and the Aedui, in the basins of the Rhodanus and its tributary the Arar (Saone), who, he says, were reckoned the three most powerful nations in all Gaul; the Arverni in the mountains of Cebenna; the Senones and Carnutes in the basin of the Liger; the Veneti and other Armorican tribes between the mouths of the Liger and Sequana.
Taking their origin from a series of lacustrine basins scattered over the plateaus and differing slightly in elevation, the Russian rivers describe immense curves before reaching the sea, and flow with a very gentle gradient, while numerous large tributaries collect their waters from over vast areas.
A great variety of monographs dealing with separate rivers and basins are available; e.g.
The rivers freeze rapidly; towards November 10th all the streams of the White Sea basin are ice-bound, and so remain for an average of 167 days; those of the Baltic, Black Sea and Caspian basins freeze later, but about December the 10th nearly all the rivers of the country are highways for sledges.
In the basins of the southern rivers they formed semi-independent military communities.
The Great Basin is not, as its name implies, a topographic cup. Its surface is of varied character, with many independent closed basins draining into lakes or "playas," none of which, however, has outlet to the sea.
There is a gutter round the level space of the stadium, with basins at intervals for the use of spectators or competitors, and a post at every hundred feet of the course, thus dividing it into six portions.
Glacial action determined the direction and character of the rivers, made numerous swamps, and, by scouring out rock basins, damming rivers and leaving morainal hollows, determined the character and formation of the lakes, of which Minnesota has upwards of io,000, a number probably exceeding that of any other state in the Union.
The general characteristics of the lakes in the north differ from those of the south, the former being generally deep, with ragged rocky shores formed by glacial scouring which caused rock basins, the latter being mostly shallow.
SAMOYEDES, a tribe of the Ural-Altaic group, scattered in small groups over an immense area, from the Altai mountains down the basins of the Ob and Yenisei, and along the shores of the Arctic ocean from the mouth of the latter river to the White Sea.
The central section nowhere presents any passes accessible to caravans, but south-westward two gaps in the range afford communication between the Tansif t and Sias basins, those respectively of Gindafi and Bibawan.
To the north-east of the Dinaric Alps extends a region of mountain, moor and forest, with deeply sunk alluvial basins, which finally expand into the lowlands of the Posavina, or Vale of the Save, forming the southernmost fringe of the Hungarian Alfold.
