All this time the gun pointer—Jim Cooper by name—alert, watchful as a mousing cat, was crouched on a little platform at the side of the gun, sighting an imaginary mark through a telescope affixed to the gun's side.

The lens of this sight was marked with tiny, hairlike crosslines, affording the pointer the means of determining with almost unerring accuracy, the exact second at which the target and the gun were in line.

The chief of the loading crew saluted.
