It was in the spring of 1896 that Pilcher built his third glider, the 'Gull, with 300 square feet of area and a weight of 55 lbs.
Joyce left 729 lbs. at the Bluff depot on December 2, reached Hut Point on December 7, and, after allowing dogs and men a good rest, he moved southward again on December 13. This proved to be the worst journey the party had made. The men had much trouble with crevasses, and they were held up by blizzards on December 16, 18, 19, 22, 23, 26, and 27.
I am confident that they would be extremely serviceable in America, if once introduced. It costs but very little to keep them, and they will do all kinds of work up to the draught of 600 or 800 lbs. You frequently see here a span of them trotting off in a cart, with brisk and even step. Sometimes they are put on as leaders to a team of horses.
An approving murmur greeted this declaration. "We must not forget," resumed Barbicane, "to what point our yesterday's debate brought us; the problem is now the following: how to give an initial speed of 12,000 yards a second to a shot 108 inches in diameter weighing 20,000 lbs. "That is the problem indeed," answered Major Elphinstone.
Tent miner's tent, pole in front, balloon silk, weight 6 lbs., dimensions 6 1/2 x 7.
Assuming then, he tells us, that the small quantity of potash required could be supplied by the soil, and that the pulp is returned to it, the loss by the crops could be fully supplied by 100 lbs. of castor cake and 10 lbs. of bones per acre. What there is actually carried off it is really very small in quantity.
Bonedust should be mixed with fine top soil, and then applied to the land, or it may be mixed with cattle manure, or applied as a surface dressing, but either of the two first-named methods of application is to be preferred. In 500 lbs. of bones there are, in round numbers, about 250 lbs. of phosphate of lime, which consists of 125 lbs. of phosphoric acid and as many of lime.
But when, later on, Barbicane substituted simple howitzers of 600 lbs. for conical shots, the captain was obliged to go down in his own estimation. It fact, these projectiles, though of mediocre velocity, drilled with holes and broke to pieces armour-plate of the best metal.
Having had various altercations with the Indians, the party reached Red River, bringing about 900 lbs. of buffalo meat in each cart, making more than one million pounds in all. The Hudson's Bay Company took a considerable amount of this, and the remainder went to supply the wants of the Red River Settlement for another year.
Penaud estimated from 20 to 30 horse-power sufficient to drive this machine, weighing with pilot and passenger 2,600 lbs., through the air at a speed of 60 miles an hour, with the wings set at an angle of incidence of two degrees. So complete was the design that it even included instruments, consisting of an aneroid, pressure indicator, an anemometer, a compass, and a level.
