"It is about twenty feet to the opening," said Levi, as he measured the distance with his eye. "The roof is not more than five feet high half the way; and, if their skulls are not harder than the limestone, General and Dummy will be likely to stave a hole in them."

"The rest of the hands are not so tall," suggested Mr. Lyon.

"I brought this rope with me without knowing that it would be of any use to us; but I find that it is just the thing we want," continued the overseer as he uncoiled the line. "Now, boys, all we will ask you to do is to hold the lanterns; but you must not go to sleep and let them fall on the stone floor."

"No danger of that," laughed Deck. "But we can work in the low place without smashing our heads."

"I am glad there is no hard work for you, boys, for you must be tired after pulling a boat twenty miles this afternoon," added Mr. Lyon.

"I am not very tired, and I can do my share of the work," replied Artie.

"So can I," added Deck.

"But you can do the most good by holding the lights," replied Levi. "One of you stand down here; and the other, with two of the lanterns, near the opening."

The boys followed this direction, Deck placing himself at the entrance, where he could light a part of the cavern and the tunnel. The overseer uncoiled his rope, and with the help of the planter lifted one of the boxes down to the floor. He then made fast the rope to it with a slip-noose, the knot on the under side, so as to carry the case over any obstructions.

Walking up to the entrance, uncoiling the line as he proceeded, he passed out of the cavern into the tunnel. Calling General and Dummy from the place where they had been told to wait, he stationed them near the door, and then carried the line, which was not less than seventy-five feet in length, to the shore of the creek.
