"We're ready for the wiring," announced Josh at last.
"I'll do that myself," said Gage. "I want it well done. Each
of you hold a lantern here."
By the light thus provided Dolph attached the light wires so that
the electric spark would be communicated to each stick in this
"mine." This was done by looping a circuit wire around each separate
stick, and connecting the wire with each detonating cap. The
dynamite, frozen on the snow crust, had thawed again at this
subterranean level.
"Now, for the last tamping," ordered Gage.
While the others worked, Dolph carefully superintended their operations.
At last the tamping was done, and the connecting wires were carried
back to the bottom of the shaft.
Here the second mine was connected in the same manner, and the wires
joined so that the circuit should be complete.
"One spark from the magneto, now," chuckled Dolph, "and both blasts
will go on at once. Whew! This old ridge will rock for a few
seconds!"
For a few moments he stood surveying his work with huge satisfaction.
