"We know that two cattle have lived and died on this field." "Undoubtedly," replied Bromley and Philip. "We have examined three sides of the field, and found that the cattle could not have come from either of those directions. Is not that so?" "It is absolutely certain," said the others. "Therefore," continued Lieutenant Coleman, "they must have come by the fourth side." This conclusion was admitted to be logical; but it provoked a storm of argument, in the course of which the soldiers got wild-eyed and red in the face. In the end, however, they consented to trim out the bushes which formed a thicket along the base of the ledge. It seemed to Lieutenant Coleman that they must find some passage here, and, sure enough, not far from the middle of this natural wall they came upon a low-browed opening, which presently narrowed down to a space not much more than five feet square. The farther end of this tunnel was closed by a pile of loose earth, which was spread out at the base, and had every appearance of having been thrown in from the other side of the ledge. The rusty shovel was brought from the fireplace of the house, and after a few minutes of vigorous digging, a ray of light broke through the roots and grass near the roof of the hole. The soldiers gave a wild cheer, and rushed out into the fresh air to cool off. "That settles it," said Lieutenant Coleman. "Hezekiah Wallstow was the old man of the mountain, and after Josiah Woodring buried him he filled up this passage. The treasure he was searching for was the very cask of gold we dug out of the fake grave--thanks to the sacrilegious behavior of the bear." "But how about the cattle?" said Bromley, still skeptical. "Easy enough," said Coleman, triumphantly. "They brought two young calves up the ladders." This hitherto unsuspected passage through the ledge made everything clear. It had evidently been wide open during all the years the old man had lived on the mountain. It might have been screened by bushes so that any chance visitors, like the hunters who came over the bridge, would be easily deceived, and not disposed to look farther than the ruined cabin and the non-committal gravestone.
