11 IX    |         we employ a quantity of powder equal to two-thirds of the
12 IX    |      and thirty-three pounds of powder, the quantity is reduced
13 IX    |        you will not require any powder at all.”~“Our friend Maston
14 IX    |         guns, the weight of the powder was reduced, as the result
15 IX    |        deciding the quantity of powder necessary to give the impulse,
16 IX    |       to employ a large-grained powder,” continued the major; “
17 IX    |        it is necessary that our powder should take fire instantaneously
18 IX    |        then to my large-grained powder, which removes those difficulties.
19 IX    |       charges Rodman employed a powder as large as chestnuts, made
20 IX    |         in cast-iron pans. This powder was hard and glittering,
21 IX    |       friends, what quantity of powder do you propose?”~The three
22 IX    |    double his 800,000 pounds of powder.”~“Sixteen hundred thousand
23 IX    |        hold to that quantity of powder. Now, 1,600,000 pounds of
24 IX    |        Now, 1,600,000 pounds of powder will create 6,000,000,000
25 IX    |       this enormous quantity of powder, while preserving to it
26 IX    |       for purposes of war. This powder, now called pyroxyle, or
27 IX    |         the top of the ordinary powder, without the latter having
28 IX    |    place of 1,600,000 pounds of powder, we shall have but 400,000
29 IX    |         projectile, cannon, and powder. Their plan was drawn up,

35 XXVIII|         quality and quantity of powder to be used. It was decided:
