The mud brought down by it, calculated at 7150 lb an hour at Bagdad, is not deposited in marshes to form alluvium, as in the case of the Euphrates, but although in flood time the river becomes at places an inland sea, rendering navigation extremely difficult and uncertain, the bulk of the mud is deposited in banks, shoals and islands in the bed of the river, and is finally carried out into the Persian Gulf.
The steam is passed through the valve and emerges at the pressure required generally from 3 lb upwards.

The wood is variable in quality and, though hard in texture, is less durable than the best oak of British growth; the heart-wood is of a light reddish brown varying to an olive tint; a Canadian specimen weighs 524 lb the cubic foot.
The wood is very heavy and hard, weighing 70 lb the cubic foot; the colour is dark brown; it is used in Spain and Italy for furniture, and in the former country for firewood and charcoal.
Cotton growing under European direction began about 1900, with the result that in 1901-1902 over 100,000 lb of cotton grown from native, American and Egyptian seed were shipped to Bremen.
Has not been shown by them, and instances exceeding 20 lb are extremely rare.
If we raise i lb of matter through a foot we do a certain amount of work against the earth's attraction; if we raise 2 lb through the same height we do twice this amount of work, and so on.
Also, the work done in raising i lb through 2 ft.
Rumford then turned up a hollow cylinder which was cast in one piece with a brass six-pounder, and having reduced the connexion between the cylinder and cannon to a narrow neck of metal, he caused a blunt borer to press against the hollow of the cylinder with a force equal to the weight of about ro,000 lb, while the casting was made to rotate in a lathe.
Taking into account the heat absorbed by the box and the metal, Rumford calculated that the heat developed was sufficient to raise 26.58 lb of water from the freezing to the boiling point, and in this calculation the heat lost by radiation and conduction was neglected.
From these experiments Joule obtained 72.692 foot-pounds in the latitude of Manchester as equivalent to the amount of heat required to raise i lb of water through 1° Fahr, from the freezing point.
With an apparatus similar to the above, but smaller, made of iron and filled with mercury, Joule obtained results varying from 772.814 foot-pounds when driving weights of about 58 lb were employed to 775.352 foot-pounds when the driving weights were only about 192 lb.
The net effective work of lifting that can be performed by a man turning a handle may be taken, for intermittent work, as being on an average about 5000 foot-lb per minute; this is equivalent to 1 ton lifted about 24 ft.
The sizes of copper wire employed have weights of too, 150, 200 and 400 lb per statute mile, and have electrical resistances (at 60° F.) of 8.782, 5.8 55, 4.39 1 and 2.195 standard ohms respectively.
Copper wire weighing 600 and 800 lb per mile has also been used to some extent.
Gutta-percha-covered copper wires were formerly largely used for the purpose of underground lines, the copper conductor weighing 40 lb per statute mile, and the gutta-percha covering 50 lb (90 lb total).
Between London and Birmingham a paper cable 116 m long and consisting of 72 copper conductors, each weighing 150 lb per statute mile, was laid in 1900.
5-7), as usually manufactured, consists of a core a in the centre of which is a strand of copper wires varying in weight for different cables between 70 and 650 lb to the nautical mile.
As used by George Stephenson on the Stockton & Darlington and Whitstable & Canterbury lines they weighed 28 lb per yard.
Long and weighed 35 lb to the yard, and they were fastened by iron wedges to chairs weighing 15 or 17 lb each.
The fishbellied rails, however, were found to break near the chairs, and from 1834 they began to be replaced with parallel rails weighing 50 lb to the yard.
Long and weighed 36 lb to the yard, manufactured in England, since there were then no mills in America able to roll them.
The fare was is., and each passenger was allowed to take baggage not exceeding 14 lb weight.
Ft., or 114 gals., of water an hour, and the steam pressure was 50 lb per square inch.
No less than 96% of the world's supply of platinum comes from the Urals; but the total output only ranges between 10,000 and 16,000 lb annually.
In the deltas of shoal rivers, with a strong tide or current and no land visible, a 5 lb lead is substituted for the log-ship; the lead rests on the bottom, and the speed is obtained in a manner similar to that previously described.
The molten sulphur accumulates on the sole, whence it is from time to time run out into a square stone receptacle, from which it is ladled into damp poplar-wood moulds and so brought into the shape of truncated cones weighing 110 to 130 lb each.
Grain from 270 lb per head in 1884-1885 to 321 lb in 1901-1902 (maize reman~s almost stationary at 158 II,); wine from 73 to 125 litres per head; oil from 12 to 13 lb per head (sugar is almost stationary at 73/4 lb per head, and coffee at about I Ib); salt from 14 to 16 lb per head.
Tobacco slightly diminished in weight at a little over I lb per head, while the gross receipts are considerably increasedby over 23/4 millions sterling since 1884-1885---showing that the quality consumed is much better.
