CHAPTER XXIII
THE PEOPLE OF THE ABYSS
Suddenly a change came over the face of things. A tingle of excitement ran along the air. Automobiles fled past, two, three, a dozen, and from them warnings were shouted to us. One of the machines swerved wildly at high speed half a block down, and the next moment, already left well behind it, the pavement was torn into a great hole by a bursting bomb. We saw the police disappearing down the cross-streets on the run, and knew that something terrible was coming. We could hear the rising roar of it.
"Our brave comrades are coming," Hartman said.
We could see the front of their column filling the street from gutter to gutter, as the last war-automobile fled past. The machine stopped for a moment just abreast of us. A soldier leaped from it, carrying something carefully in his hands. This, with the same care, he deposited in the gutter. Then he leaped back to his seat and the machine dashed on, took the turn at the corner, and was gone from sight. Hartman ran to the gutter and stooped over the object.
"Keep back," he warned me.
