The man called Blaisdell stepped over to the middle of the room. Stooping, he seemed to dig his fingers under a certain rough plank of the floor. As a usual thing such border cabins have only the hard earth to serve as a floor; but the man who built this shack had gone to the trouble of cutting timber, splitting it, and even making rough planks with which to cover the earth.

When Blaisdell had pulled one of these up he bent over. Bob felt himself shivering with eagerness and anticipation. Of course there could be but one explanation of the actions of the two robbers. Having agreed to part company they were now about to divide the spoils.

Since he had figured it all out in this way, Bob was therefore not much surprised to see Blaisdell toss out what looked to be a small bag. After that he bent down again and secured a second. Mr. Riley had said there were three; but the man made no further movement looking to unearthing another sack.

Well, if they managed to recover two-thirds of the treasure, that was worth while, Bob thought, as he fixed his eyes on the bundles. It struck him that Blaisdell must be a much stronger man than his thin appearance would seem to indicate. Mr. Riley had said that each of the three sacks must have weighed in the neighborhood of sixty pounds; and here was a man who thought little of tossing such a package aside, as though it were next to nothing.

Bob expected to see each of the men pick up one of the bags, and start for the door. He even found himself wondering what Frank’s next move might be. Would he try to stop them from departing? Undoubtedly they must have horses somewhere close by, for they had come there mounted.

They sat down again, as if to talk matters over once more, with the two sacks of treasure close to their feet.

If only now Reddy and Blaisdell would go out of the shack for a short time, to saddle their horses, it might be that a fine chance would come up for the recovery of the treasure! Bob believed he could slip inside the cabin himself, and carry off one of the sacks.

Suddenly Bob saw something moving near the open door. At first he could not make out what it was that kept advancing so strangely.

Presently he managed to figure out what seemed to be a human head—no, there were two of them, belonging to men who had covered their bodies with an old blanket, and were thus creeping, inch by inch, toward the inmates of the shack.

Reddy and Blaisdell did not see what was coming, because they happened to have their backs toward the door. And Bob found himself strangely thrilled by the prospect of an encounter in which he and his companions would have no part.
