But, you will recall, they are told to "kape still" and "come down heavy on the cast-iron drill".

The only way I can interpret this is that the drill, itself similar to a tarrier-borer, or bung augur, would be turned and then braced by an assistant and pounded in by a sledge hammer to take out the next bit of the hole.

The tarrier was probably the drill holder, and he would have to be keeping it still when the hammer came down. Then he would crank it in a tiny bit for the next blow.

Fourteen of them drilling on the rock at once, all being hammered down and ordered about by a foreman must have been a bustling, noisy scene indeed --especially when the blasts went off. Man, the raw effort that went into a scene like that is mind boggling by todays standards, where Daisy-Ettas do all the work.
