Farther on, the subaltern and a bayonet man carried on the good work with howls of joy, while a small party of bombers, having found a large sump pit covered by boards in a communication trench, removed the boards just in time to catch a relief party of six who came rushing up the trench.
There were falls in his course, and he clambered across rough hills of rock and squeezed through narrow openings; but every step brought him nearer to the slope, and this thought nerved him to still greater effort. Yet he could not wholly escape the water of the sump. He had still to pass through it. It was cold and black. It came to his ankles as he trudged along.
"Sump too uss ain't it?" asked the sober man with bated breath and obvious distrust of his tongue. "Mag nee feque! M. Louis Laplante, look you there," cried the Frenchman, catching sight of his full figure in the mirror and instantly striking a pose of admiration. Then he twirled fiercely at both ends of his mustache till it stood out with the wire finish of a Parisian dandy.
Against the sides build half-brick walls in cement, with glazed face, and lay the floor with glazed bricks flat. The general principles of this construction I show in the accompanying illustration. Where the bath is lower than the drain, all that can be done is to drain out as much as possible and pump the remaining water from a "sump" provided in a suitable position.
Fairchild had killed the engines and run forward to where Harry, one big hand behind the carbide flare, was peering down the shaft. "The sump it's a little 'ole at the bottom of the shaft to 'old any water that 'appens to seep in. That means the 'ole drift is unwatered." "Then the pumping job 's over?" "Yeh." Harry rose. "You stay 'ere and dismantle the pumps, so we can send 'em back.
After a few moments of rest, he started again, examining every inch of the ground as he went. This time he found where Ralph had turned off into the air-way. He traced his foot-prints up through an entrance into the chambers and there they were again lost. But he passed on through the open places, calling as he went, and came finally to the sump near the foot of the slope.
The problem of getting an engine on the ground was one that could be worked out later, but in the meanwhile the water was rising in the sump and the pumps would soon be submerged. There were two shifts of miners who would have to be discharged and yes, the engine crew, too.
We got to get help in a hurry. You ride to town and rustle men. Bring out plenty of dynamite and gunnysacks. Lucky we got the tools out here we brought to build the sump holes." "Betcha! We'll need a lot o' grub, too." The cattleman nodded agreement. "And coffee. Cayn't have too much coffee. It's food and drink and helps keep the men awake." "I'll remember."
For an instant it seemed that the great car would turn over into the sump, but the next instant it was past. It struck the bottom of the hollow a mighty wallop, and bounced and upended to the steep pitch of the climb.
The conditions were as follows: The mine produces 11,000 gallons of water every twenty-four hours. The sump holds 11,000 gallons. Two entries that can be dammed up give a storage of 16,500 gallons, making a total storage capacity of 27,500 gallons. It takes sixty hours for the mine to produce this quantity of water, which allows for days that the wind does not blow.
