In these very hot drifts the fatality was large.
The trade winds give rise, in the region most exposed to their influence, to two westward-moving drifts - the equatorial currents, which are separated in parts of their course by currents moving in the opposite direction along the equatorial belt.
The second branch proceeds north-westwards towards the West Indies, where it mingles with the waters of the northern equatorial; and the two drifts, blocked by the
Half walking in the paths, half working our way through the lesser drifts, we succeeded in reaching a pine grove just outside a broad pasture.
We've got some three foot drifts on the road out here.
Elsewhere local surface currents are developed, either drifts due to the direct action of the winds, or streams produced by wind action heaping water up against the land; but these nowhere rise to the dignity of a distinct current system, although they are often sufficient to obliterate the feeble tidal action characteristic of the Mediterranean.
The clays of the Rolling Downs formation overlie a series of sands and drifts, saturated with water under high pressure, which discharges at the surface as a flowing well, when a borehole pierces the impermeable cover.
Other precious stones, including the sapphire, emerald, oriental emerald, ruby, opal, amethyst, garnet, chrysolite, topaz, cairngorm, onyx, zircon, etc., have been found in the gold and tin bearing drifts and river gravels in numerous localities throughout the states.
The manatee, or sea-cow, frequents the mouths of rivers, the sargasso drifts, and the regions of submarine fresh-water springs off the coast.
About noon the 2nd of February Napoleon attacked them, but the weather was terrible, and the ground so heavy that his favourite artillery, the mainstay of his whole system of warfare, was useless and in the drifts of snow which at intervals swept across the field, the columns lost their direction and many were severely handled by the Cossacks.
The surface drifts of the greater part of the state, which are almost wholly of glacial origin, have provided Minnesota with a remarkably fertile soil.
The empirical data on which the hydrodynamical investigations are based are: (I) observed velocities and directions of oceanic currents and drifts; (2) salinity; (3) density; (4) temperature of the sea water in situ; (5) oceanic soundings.
The air, after being chilled on the plateaus during the winter, drifts, owing to its greater density, down upon the lowlands; hence in the region of the lower Lena there obtains an exceedingly low temperature throughout the winter, and Verkhoyansk, in 67°N., is the pole of cold of the eastern hemisphere.
The Delagoa Bay railway being at length completed to Pretoria and Johannesburg, Kruger determined to take steps to bring the Rand traffic over The Netherlands railway Drifts began by putting a prohibitive tariff on goods from the Vaal river.
Kruger then closed the drifts (or fords) on the river by which the wagons crossed.
The Tugela is crossed by well-known drifts, to which roads from Natal and Zululand converge.
As the sinking of shafts or the driving of narrow entries or drifts is expensive, and as the mineral extracted rarely pays more than a small fraction of the cost, it is usual to plan this exploratory work so that the openings made shall serve some useful purpose later.
As soon as it appears reasonably certain that the property is workable the mine will be opened by one or more shafts, drifts or tunnels, and the underground passages for active mining operations will be started.
Drifts, entries and tunnels find their chief application in mining regions cut by deep valleys.
Drifts and inclined shafts following the deposit may prove difficult of maintenance when the workings become large and settlement of the overlying strata begins.
Natural ventilation is impracticable in flat deposits worked by drifts and without shafts.
Forty years before his visit a flood is said to have occurred, which passed down the river till it was blocked by sand-drifts at Thuwerat, 50 m.
The area is laid out by two pairs of level drifts, parallel to each other, about 150 yds.
We may gradually invent means of tracing more and more closely the average drifts of translation or orientation, or of changes of arrangement, of the atoms; but there will always remain an unaveraged residue devoid of any recognized regularity, which we can only estimate by its total amount.
Sapphire is widely distributed through the gold-bearing drifts of Victoria, New South Wales and Queensland, but the blue colour of the Australian stones is usually dark, and it is notable that green tints are not infrequent.
This building, erected in the 15th century amid the barren dunes bordering the east shore of the estuary near its mouth, in place of a more ancient oratory, was long buried beneath drifts of sand.
The prevalence of south-west winds during nine months of the year and of north-west during three (April - June) has a strong influence on the temperature and rainfall, tides, river mouths and outlets, and also, geologically, on dunes and sand drifts, and on fens and the accumulation of clay on the coast.
" The occurrence of stones and boulders far removed from their parent source early attracted the attention of geologists, but for a long period the phenomena, now known as of glacial origin, were unexplained, and the drifts were looked upon as little more than ` extraneous rubbish,' the product of geological agents, quite distinct from those which helped to form the more ` solid ' rocks that underlie them."
But, whilst recognizing the existence of local drifts and systems, and admitting the possibility of relative motion between the nearer and more distant, or other classes of stars, it is;only recently that astronomers have seriously doubted the correctness of the hypothesis of random distribution of stellar motions as at least a rough representation of the truth.
These two streams or drifts prevail in every part of the sky examined, and contain nearly equal numbers of stars; that is to say, in whatever part of the sky we look about half the stars are found to belong to one and half to the other of the two great drifts.
This hypothesis of two star-drifts does not imply that all the stars move in one or other of two directions.
North of the equator the surface circulation is under the control of the monsoons, and changes with them, the currents consisting chiefly of north-east and south-west drifts in the open sea, and induced streams following the coasts.
On the west coast of Madagascar and on the banks of the African coast south of 30° 5., reaction currents or "backdrifts" move in the opposite direction along the flanks of the Agulhas current; these back-drifts are of great importance to navigation.
In winter the gales often fill the streets to the depth of several feet, with drifts of sand from the surrounding dunes, which, however, are noted in summer for the dry and bracing air.
Thereupon President Kruger arbitrarily closed the drifts (fords) on the Vaal river, and thus prevented through waggon traffic, causing an enormous block of waggons on the banks of the Vaal.
P. Schreiner was one, and a protest was then sent by Mr Chamberlain stating that the government would regard the closing of the drifts as a breach of the London Convention, and as an unfriendly action calling for the gravest remonstrance.
President Kruger at once reopened the drifts, and undertook that he would issue no further proclamation on the subject except after consultation with the imperial government.
Again, there are chambers with drifts of snowy crystals of the sulphate of magnesia, the ceilings so thickly covered with their efflorescence that a loud concussion will cause them to fall like flakes of snow.
P. pinaster, the cluster pine or pinaster, is an important species from its vigorous growth in the sand-drifts of the coast, for the purpose of binding which it has been grown more extensively and successfully than any other tree, especially on the dunes of the Bay of Biscay.
It seems difficult to account for the very remarkable and unsymmetrical distribution of the motions, unless we suppose that the stars form two more or less separate systems superposed; and it has been found possible by assuming two drifts with suitably assigned velocities to account very satisfactorily for the observed motions.
The phenomenon of two drifts was discovered by an examination of the Bradley proper motions (Brit.
Dyson has traced the presence of the two drifts in all parts of the sky.
