Near the center of the clearing, and not far from the drum, or altar, he commenced to dig.This was harder work than turning up the freshly excavated earth at the grave, but Tarzan of the Apes was persevering and so he kept at his labor until he was rewarded by seeing a hole sufficiently deep to receive the chest and effectually hide it from view.
Why had he gone to all this labor without knowing the value of the contents of the chest?
Tarzan of the Apes had a man's figure and a man's brain, but he was an ape by training and environment.His brain told him that the chest contained something valuable, or the men would not have hidden it.His training had taught him to imitate whatever was new and unusual, and now the natural curiosity, which is as common to men as to apes, prompted him to open the chest and examine its contents.
But the heavy lock and massive iron bands baffled both his cunning and his immense strength, so that he was compelled to bury the chest without having his curiosity satisfied.
By the time Tarzan had hunted his way back to the vicinity of the cabin, feeding as he went, it was quite dark.
Within the little building a light was burning, for Clayton had found an unopened tin of oil which had stood intact for twenty years, a part of the supplies left with the Claytons by Black Michael.The lamps also were still useable, and thus the interior of the cabin appeared as bright as day to the astonished Tarzan.
He had often wondered at the exact purpose of the lamps.
His reading and the pictures had told him what they were, but he had no idea of how they could be made to produce the wondrous sunlight that some of his pictures had portrayed them as diffusing upon all surrounding objects.
As he approached the window nearest the door he saw that the cabin had been divided into two rooms by a rough partition of boughs and sailcloth.
In the front room were the three men; the two older deep in argument, while the younger, tilted back against the wall on an improvised stool, was deeply engrossed in reading one of Tarzan's books.
