"Art. 5. Ask him as many questions as you like. He is paid to answer

On the second day the scene of my operations was changed to the eighth
level, a hundred feet below that of the first. It was a long gallery
winding away through the mountain, and connecting a mile beyond with
another shaft opening on another hill, so that the heavy air was
tempered by a constant mild breeze.

Side shafts, just large enough for the ore-cars to pass, pierced far
back into the mountain at frequent intervals. Back in these it was
furnace hot. From them the day-gang took out 115 car-loads, though the
chute was blocked now and then by huge rocks that must be "shot" by a
small charge of dynamite stuck on them, a new way of "shooting the
chutes" that was like striking the ear-drums with a club.
