The following were the data for a day of 24 hours, with an interval of half an hour: 8:55 P.M. one day to 8:55 P.M. the next, interval 8:30 to 9 A.M. Anthracite used, 18.4 cwt.; coke used, 3.42 cwt.; water used for steam injection, 217.3 gallons; water used in scrubber, 4,106 gallons; water used in cooling the cylinder, 20,000 gallons; oil used in cylinder, 14.84 pounds; grease, 1.8 pounds; revolutions of machine, 142,157, or 100.8 per minute; effective work, 75.86 French horse power, or 77.4 British; gas used, 6,742 cubic feet per hour, at 772 mm. pressure and 70.7° F., or 83.7 cubic feet per effective horse power; efficiency, 69 per cent.
Where before it required 3 tons of coke to melt 1 ton of steel, the same thing was now done with 35 cwt. of very poor slack. Though it was apparently easy to make crucible steel castings, it was not in reality easy to make a true steel, that was to say, to make a metal that contained only the correct proportions of carbon and silicon and manganese.
This core was served with hemp saturated in a preservative solution, and on the hemp as a padding were spirally wound eighteen single wires of soft steel, each covered with fine strands of Manilla yam steeped in the preservative. The weight of the new cable was 35.75 cwt. per knot, or nearly twice the weight of the old, and it was stronger in proportion. Ten years before, Mr.
As as preliminary experiment, I placed a spare 5/16 ball between the crushing faces of the new testing machine at South Kensington, and applied a gradually increasing force up to 7 tons 91/2 cwt., at which it showed no signs of distress. On removing it I found that it had buried itself over an angle of about 60 deg. in the hard steel faces, faces so hard that a file would not touch them.
N.B. Took out 5 cases Ap. 5, 1806, besides the boddies. Avging 3/4 cwt. 1 case jewels. We left the clothes, wh. were many. The second entry appeared to have been penned by the same hand as the original, but more neatly and some while later. The ink, at any rate, was blacker and fresher. It ran: S.W. ann. aetat. 37.
600 cwt. flour, first and second quality. 35 bushels rough barley. 10 half-firkins butter, 28 lbs. each. 10 bushels Indian corn. 200 cwt. best kiln-dried flour. 60 firkins butter, 56 lbs. each. 240 lbs. cheese. 60 hams. Thus it happens that the Red River farmer finds a "sure market" for six or eight bushels of wheat and no more.
Their provision was calculated to last them 4 months, and was distributed together with the tools, amunition, and camp necessaries on 18 packs, averaging at the start about 150 lbs. each. It consisted of 1200 lbs. flour, 3 cwt. sugar, 35 lbs. of tea, 40 lbs. currants and raisins, 20 lbs. peas, 20 lbs. jams, salt, etc.
Here, however, no land which is adapted to the cultivation of tobacco is allowed to be used for any other purpose of agriculture. By grafting new monopolies upon those already existing, he believes that the tobacco produce can be increased from 182,102 cwt.
In the case in question, the average crop for the last five years, has been 3-3/4 cwt. an acre. The expenses were 111-1/2 rupees an acre, and the average profit 111-1/10 rupees per acre per annum, or rather over £7 2s. 6d. an acre.
A species of silk cotton, or ether down, is produced on a large tree, called the pullam tree. The quantity which the usual size bears may be computed at about 4 cwt. in pods of 6 to 9 inches long, 4-1/2 in circumference, and about 1-1/2 inch in diameter, which, upon being exposed to the heat of the sun, is distended to an incredible bulk.
