The old warrior rose, suddenly erect, and turned toward them, but the boys were hidden in the gloom. Then he hurried to the dead stub beside the chasm wall. Again he reached far up, rubbing his hand along its surface.
"I'm going to have a look at that tree!" whispered Wabi. "Something is puzzling Mukoki. Are you coming?"
He hurried across the rock-strewn opening, but Rod hung back. He could not understand his companions. For weeks and months they had planned to find this third waterfall. Visions of a great treasure had been constantly before their eyes, and now that they were here, with the gold perhaps under their very feet, both Mukoki and Wabigoon were more interested in a dead stub than in their search for it! His own heart was almost bursting with excitement. The very air which he breathed in the old cabin set his blood leaping with anticipation. Here those earlier adventurers had lived half a century or more ago. In it the life-blood of the murdered John Ball might have ebbed away. In this cabin the men whose skeletons he had found had slept, and planned, and measured their gold. And the gold! It was that and not the stub that interested Roderick Drew! Where was the lost treasure? Surely the old cabin must hold some clue for them, it would at least tell them more than the limbless white corpse of a tree!
From the door he looked back into the dank gloom, straining his eyes to see, and then glanced across the opening. Wabi had reached the stub, and both he and Mukoki were on their knees beside it. Probably they have found the marks of a lynx or a bear, thought Rod. A dozen paces away something else caught his eyes, a fallen red pine, dry and heavy with pitch, and in less than a minute he had gone to it and was back with a torch. Breathlessly he touched the tiny flame of a match to the stick. For a moment the pitch sputtered and hissed, then flared into light, and Rod held the burning wood above his head.
The young gold seeker's first look about him was disappointing. Nothing but the bare walls met his eyes. Then, in the farthest corner, he observed something that in the dancing torch-light was darker than the logs themselves, and he moved toward it. It was a tiny shelf, not more than a foot long, and upon it was a small tin box, black and rust-eaten by the passing of ages. With trembling fingers Rod took it in his hand. It was very light, probably empty. In it he might find the dust of John Ball's last tobacco. Then, suddenly, as he thought of this, he stopped in his search and a muffled exclamation of surprise fell from him. In the glow of the torch he looked at the tin box. It was crumbling with age and he might easily have crushed it in his hand—and yet it was still a tin box! If this box had remained why had not other things? Where were the pans and kettles, the pail and frying-pan, knives, cups and other articles which John Ball and the two Frenchmen must at one time have possessed in this cabin?
He returned to the door. Mukoki and Wabigoon were still at the dead stub. Even the flare of light in the old cabin had not attracted them. Tossing his torch away Rod tore off the top of the tin box. Something fell at his feet, and as he reached for it he saw that it was a little roll of paper, almost as discolored as the rust-eaten box itself. As gently as Mukoki had unrolled the precious birchbark map a few months before he smoothed out the paper. The edges of it broke and crumbled under his fingers, but the inner side of the roll was still quite white. Mukoki and Wabigoon, looking back, saw him suddenly turn toward them with a shrill cry on his lips, and the next instant he was racing in their direction, shouting wildly at every step.
"The gold!" he shrieked. "The gold! Hurrah!"
He was almost sobbing in his excitement when he stopped between them, holding out the bit of paper.
"I found it in the cabin—in a tin box! See, it's John Ball's writing—the writing that was on the old map! I found it—in a tin box—"
Wabi seized the paper. His own breath came more quickly when he saw what was upon it. There were a few lines of writing, dim but still legible, and a number of figures. Across the top of the paper was written,
