The lumberman was willing, and lighting a fresh torch, they moved around the circular chamber. At one point they saw an opening leading into a second chamber. Here were a number of boxes and casks, all covered with dust and dirt, the accumulation of years. Prying open one of the boxes which was handy, they discovered that it contained canned vegetables. A second box contained dress goods, and a third some candles. A cask close at hand was marked "Cognac."
"This was a regular smugglers' hangout," said Peterson. "Those boxes must contain stuff of some value. Rover, we have made a haul by coming here."
"Yes, but I am forgetting all about my brothers," added Dick hastily.
"Let us leave this alone for the present. I guess it is safe enough."
"No doubt, since it has rested undisturbed so many years."
They left the storeroom, as it may properly be termed, and returned to the circular chamber.
At first they could find no further opening, but then Dick saw a thin shaft of light coming from a corner. Here there was a flat rock which was easily pulled aside. A broad opening led upward to the outer world.
"Safe, so far as getting out is concerned," remarked Peterson. "All told, I reckon we had quite a lucky tumble, after all."
"If Larry's ankle isn't too bad."
They hurried back to where Larry had been left, and found him still nursing his ankle, which had swollen to the size of his knee. He tried to stand upon it, but the pain was so great he was glad enough to sit down again.
He listened in open-mouthed wonder to what Dick had to tell. "A treasure cave!" he cried. "Who would have dreamed of such a thing on Lake Huron!"
