THE MAN-KILLER CLAIMS A SACRIFICE.
In the days that followed Tom Reade and Harry Hazelton were more continuously and seriously busy than they had ever been before in their lives.
Sometimes it happens that engineers come upon a quicksand that apparently has no bottom.

It will be filled and apparently the earth on top is solid.

After a few days there will follow either a gradual shifting away or a sudden cave in, and the quicksand must once more be attacked.
This condition had been experienced more than a dozen times with the Man-killer before Tom and Harry had been called to solve the problem.
There is no definite way of attacking a quicksand.

Much must depend upon the local conditions.
