than 28° north or south from the equator, so that it might be aimed
vertically at the Moon in the zenith. The bullet was to be animated with
an initial velocity of 12,000 yards to the second. It was to be fired
off on the night of December 1st, at thirteen minutes and twenty seconds
before eleven o'clock, precisely. Four days afterwards it was to hit the
Moon, at the very moment that she reached her _perigee_, that is to say,
her nearest point to the Earth, about 228,000 miles distant.

The leading members of the Club, namely President Barbican, Secretary
Marston, Major Elphinstone and General Morgan, forming the executive
committee, held several meetings to discuss the shape and material of
the bullet, the nature and position of the cannon, and the quantity and
quality of the powder. The decision soon arrived at was as follows:
1st--The bullet was to be a hollow aluminium shell, its diameter nine
feet, its walls a foot in thickness, and its weight 19,250 pounds;
2nd--The cannon was to be a columbiad 900 feet in length, a well of that
depth forming the vertical mould in which it was to be cast, and
3rd--The powder was to be 400 thousand pounds of gun cotton, which, by
developing more than 200 thousand millions of cubic feet of gas under
the projectile, would easily send it as far as our satellite.

These questions settled, Barbican, aided by Murphy, the Chief Engineer
of the Cold Spring Iron Works, selected a spot in Florida, near the 27th
degree north latitude, called Stony Hill, where after the performance of
many wonderful feats in mining engineering, the Columbiad was
successfully cast.

Things had reached this state when an incident occurred which excited
the general interest a hundred fold.
