As they stood here and looked at the scene before them, they saw, not very far away, a mound of earth. They had seen this from the boat as they approached, and had at once thought that it might be the very ground removed from the earth in forming one of the numerous pits. In digging these pits the earth would be raised, and thrown on one side. “Sure that’s what I towld ye,” said Pat. “Ye know there must be a deep hole from the height of it.” “Yes,” said Bart. “There must be a hole there. Come, let’s have a look at it.” With these words the two started forward, and walked towards the heap of earth. As they came up, they noticed that the soil consisted of clay of a dull bluish tinge, like pale slate, and they recognized at once the bluish clay of which the landlord had spoken. The heap of earth was of considerable dimensions. They both walked up it, and on reaching the top, they saw on the other side an opening in the ground. Hurrying down towards it, they recognized in it at once one of those pits made by some one of the companies digging here. The mouth of it was about six feet long and four feet wide. The sides were stayed up by planks. They could not see far down, however, for the pit contained water, which came to within a dozen feet of the surface. How deep the pit was they could not see; but they at once conjectured that this was one of those pits mentioned by the landlord, where the diggers in search of the “drain” had broken into it, and had thus been compelled to fly from the waters that poured in upon them. This pit was flooded (as the landlord had said) from “Kidd’s drain.” After examining this pit, they proceeded farther, and saw another mound not far away. It was just like this, of about the same dimensions, and consisting of the same bluish clay. To this they directed their steps, knowing now that another pit might be expected here, and in this expectation they were not disappointed. There was a pit here of precisely the same appearance as the one which they had just examined, stayed up in the same way around the sides by stout planks, and of about the same size. Like the other, it was also full of water. Here too, then, as they thought, the diggers had broken into the “drain,” and had flooded the pit. The occurrence of these two pits, both full of water, showed them, in a very striking and very significant manner, the difficulties that those encountered who sought to penetrate to the hidden treasure. But the boys were curious to see some pit that might not be full of water, so as to see with their own eyes the depth of these excavations. The landlord had mentioned a hundred feet. Such a depth as that, they knew, exceeded the height of an ordinary church spire, and they both wondered whether it would be possible for them to descend. They, therefore, turned away from this pit after a slight examination, and looked around for others.
