"Certainly; but what would be bad for a gun destined for long service would not be so for our Columbiad. We run no danger of explosion, and the powder must immediately take fire to make its mechanical effect complete."
"We might make several touchholes," said J.T. Maston, "so as to set fire to it in several places at the same time."
"No doubt," answered Elphinstone, "but that would make the working of it more difficult. I therefore come back to my large-grained powder that removes these difficulties."
"So be it," answered the general.
"To load his Columbiad," resumed the major, "Rodman used a powder in grains as large as chestnuts, made of willow charcoal, simply rarefied in cast-iron pans. This powder was hard and shining, left no stain on the hands, contained a great proportion of hydrogen and oxygen, deflagrated instantaneously, and, though very brittle, did not much damage the mouthpiece."
"Well, it seems to me," answered J.T. Maston, "that we have nothing to hesitate about, and that our choice is made."
"Unless you prefer gold-powder," replied the major, laughing, which provoked a threatening gesture from the steel hook of his susceptible friend.

"Now, my friends, what quantity of powder do you propose?"
The three members of the Gun Club looked at one another for the space of a minute.
