"But there are others," said Brooks, with an odd smile on his face. Meantime, Desmond followed the crevice until he came to the stone wall. He knew about the same wall, but he was working on a certain theory. He was like the Captain Kidd treasure-seekers--the discouragement of others did not in any way discourage him, and we will here say that a similar persistence in any walk of life, as a rule, leads to great results. Desmond, as stated, arrived opposite the stone wall, and he commenced a calm, steady, determined examination. First appearances would have discouraged any man, being faced as he was by a solid, smooth face of rock. He stood contemplating the mass before him, and then with the ray of light from his lantern he ran all over the rock. "By ginger!" he muttered at last, "I reckon it's true. There does not appear a hole big enough in that rock for a spider to crawl through; but, hang me! I've got an impression." There appeared to be a break in the rock just where it joined with the roof of the cave. Desmond rolled a bowlder over against the rock and mounted, and ran his finger over the crack. It was not a large crack and offered no encouragement, but the lad was determined not to be satisfied until he had established facts beyond all dispute. He ran his finger, as stated, along the crack, and his knuckle pressed against the roof, and to his surprise there appeared to be a loosening. He examined it and he saw that there was a uniform crack running along the roof inclosing a space about two feet square. The lad instinctively pressed on the center between the cracks, and lo, there appeared to be a piece of the roof that yielded. He pressed harder and satisfied himself that the piece of rock between the cracks in the roof was movable. The discovery caused his heart to stand still, and he muttered: "Great Scott! but I've found it." He flashed the light on the crack and thought he could discern where there had been some chiseling. He made every effort to shift the rock out of its place, but it was too much for him, owing to the fact that he could just about reach it. He did not have purchase enough to exert his full strength. He stepped down on the floor again and commenced to consider, and then he determined to return to the main cave and solicit Brooks and Creedon to go to his aid. When he re-entered the main cavern Creedon with a laugh said: "Well, lad, did you run up against a stone wall?" "I did." "I told you it was of no use to search these crevices. I've explored every inch." "You have?" "Yes." "I think not." Brooks knew Desmond so well he discerned that the lad had really made a discovery, but he said nothing. "You think not, eh?" "I do." "That would hint that you had found something." "I have." "What have you found?" "I don't know yet, but I am certain I have found a cranny or nook that you never explored." "You have?" "I have." "What have you found?" "Oh, it may be that it's 'tellings,' as the boys say."
