Temple had begun work at that point. He was extending an embankment thence toward the point where the county line must be crossed. On this he was laying a temporary track as fast as it was extended, in order that his earth cars might be pushed over it with their loads of filling material.
Duncan's first look at the progress of the work convinced him that it could not be completed within the time allowed, unless a much larger working force could be secured.
He instantly telegraphed to Hallam:
Must have more men immediately. If you can send two hundred at once there is a bare possibility of success, provided weather conditions do not grow worse. But without that many men failure is inevitable. Why not send all your miners here?
Hallam, in his habitual way, acted promptly and with vigor. Leaving Stafford to hire all the men who could be secured in Cairo, he himself hurried to the mines, and by promising double wages, induced most of the men there to go for the time being into the work of railroad construction. Within two or three days the total force at Duncan's command numbered somewhat more than two hundred men.
"We ought to have fifty or a hundred more," he said, "particularly as the miners are new to this sort of work; but, as we can't get them, we must do our best with the force we have."
After consultation with Temple, he divided the force into three shifts, and kept the work going night and day, without cessation. For a time the rapid progress made gave Duncan confidence in his ultimate success. In that confidence Temple shared, but with a reservation.
"I'm afraid we're in for a freshet," he said. "The rivers are all rising, and the rain is almost continuous now. All this region, except a hill here and there, lies lower than the flood levels of the Ohio River on one side, and the Mississippi on the other. If the rise continues, we shall have both rivers on us within a few days."
"Is there any way in which to meet that difficulty?" asked Duncan anxiously.
"Yes—possibly," Temple responded, slowly and hesitatingly. "We might build a crib across the space still to be filled in, and make it serve the purposes of a coffer dam in some degree. By doing that, we can keep the work going, even if the overflow from the rivers comes upon us. But the building of the crib will take time, and we've no time to waste, you know."
