The discovery took place at about four o'clock, when Hart's attention was attracted by the sound of a motor outside his shelter. Investigating, he saw a large truck on the main drive several rods away; but could not reach it before the sound of his feet on the gravel had revealed his approach. The men hastily placed a large box in the truck and drove away toward the street before they could be overtaken; and since no known grave was disturbed, Hart believes that this box was an object which they wished to bury.
