Two men operating a steam drill They are drilling a hole, to a certain depth, in the stone wall. The man at right has a narrow stick that can be inserted into the hole to check the hole's depth. When the hole is deep enough, dynamite will be jammed into the hole until the crew is ready to blast away the rock wall, to make room for a new railroad or street or etc. To see my other vintage images, Search: Prestor vintage work
