ADVENTURES OF CAPTAIN HORN
Then he turned squarely about, entered the passage, and walked along it until he came to the door of the room which had once been occupied by Captain Horn.
"I'll try it inside first," said Burke to himself, "and then I'll go outside."
He walked through the rooms, turning to the right about ten feet when he came to the middle apartment,—for the door here was not opposite to the others,—but coming back again to his line of march as soon as he was on the other side. He proceeded until he reached the large cave, open at the top, which was the last of these compartments. This was an extensive cavern, the back part being, however, so much impeded by rocks that had fallen from the roof that it was difficult for him to make any progress, and the numbering of his steps depended very much upon calculation. But when he reached the farthest wall, Burke believed that he had gone about as great a distance as he had stepped off in the cave of the lake.
"But how in the mischief," thought he, "am I to find anything here?" He held up his lantern and looked about. "I can't move these rocks to see what is under them."
As he gazed around, he noticed that the southeast corner seemed to be more regular than the rest of the wall of the cave. In fact, it was almost a right-angled corner, and seemed to have been roughly cut into that shape. Instantly Burke was in the corner. He found the eastern wall quite smooth for a space about a foot wide and extending about two yards from the floor. In this he perceived lines of crevice marking out a rectangular space some six inches wide and four feet in height.
