On the completion of the Columbiad the public interest centered in the projectile¹ itself, the vehicle which was destined² to carry the three hardy³ adventurers into space.

The new plans had been sent to Breadwill and Co., of Albany, with the request for their speedy execution. The projectile was consequently cast on the 2nd of November, and immediately forwarded by the Eastern Railway to Stones Hill, which it reached without accident on the 10th of that month, where Michel Ardan, Barbicane, and Nicholl were waiting impatiently for it.

The projectile had now to be filled to the depth of three feet with a bed of water, intended to support a water-tight wooden disc, which worked easily within the walls of the projectile. It was upon this kind of raft that the travelers were to take their place. This body of water was divided by horizontal partitions, which the shock of the departure would have to break in succession. Then each sheet of the water, from the lowest to the highest, running off into escape tubes toward the top of the projectile, constituted a kind of spring; and the wooden disc, supplied with extremely powerful plugs, could not strike the lowest plate except after breaking successively the different partitions. Undoubtedly⁴ the travelers would still have to encounter a violent recoil⁵ after the complete escapement of the water; but the first shock would be almost entirely⁶ destroyed by this powerful spring. The upper parts of the walls were lined with a thick padding of leather, fastened upon springs of the best steel, behind which the escape tubes were completely concealed⁷; thus all imaginable precautions had been taken for averting⁸ the first shock; and if they did get crushed, they must, as Michel Ardan said, be made of very bad materials.
