"Only it is more expensive." "What matter?" cried J. T. Maston. "Finally, it imparts to projectiles a velocity four times superior to that of gunpowder. I will even add, that if we mix with it one-eighth of its own weight of nitrate of potass, its expansive force is again considerably augmented." "Will that be necessary?" asked the major. "I think not," replied Barbicane. "So, then, in place of 1,600,000 lbs. of powder, we shall have but 400,000 lbs. of fulminating cotton; and since we can, without danger, compress 500 lbs. of cotton into 27 cubic feet, the whole quantity will not occupy a height of more than 180 feet within the bore of the Columbiad. In this way the shot will have more than 700 feet of bore to traverse under a force of 6,000,000,000 litres of gas before taking its flight towards the moon." At this junction J. T. Maston could not repress his emotion; he flung himself into the arms of his friend with the violence of a projectile, and Barbicane would have been stove in if he had not been bomb-proof. This incident terminated the third meeting of the Committee. Barbicane and his bold colleagues, to whom nothing seemed impossible, had succeeded in solving the complex problems of projectile, cannon, and powder. Their plan was drawn up, and it only remained to put it in execution. "A mere matter of detail, a bagatelle," said J. T. Maston. Illustration: CAPTAIN NICHOLL CHAPTER X. ONE ENEMY _v._ TWENTY-FIVE MILLIONS OF FRIENDS. The American public took a lively interest in the smallest details of the enterprise of the Gun Club. It followed day by day the discussions of the committee. The most simple preparation for the great experiment, the questions of figures which it involved, the mechanical difficulties to be resolved—in one word, the entire plan of work—roused the popular excitement to the highest pitch. The purely scientific attraction was suddenly intensified by the following incident:— We have seen what legions of admirers and friends Barbicane's project had rallied round its author. There was, however, one single individual alone in all the States of the Union who protested against the attempt of the Gun Club. He attacked it furiously on every opportunity, and human nature is such that Barbicane felt more keenly the opposition of that one man than he did the applause of all the others. He was well aware of the motive of this antipathy, the origin of this solitary enmity, the cause of its personality and old standing, and in what rivalry of self-love it had its rise. This persevering enemy the President of the Gun Club had never seen. Fortunate that it was so, for a meeting between the two men would certainly have been attended with serious consequences. This rival was a man of science, like Barbicane himself, of a fiery, daring, and violent disposition; a pure Yankee. His name was Captain Nicholl; he lived at Philadelphia.
