Cheechako continued to be puzzled and to grow more puzzled. Two or three times he cocked up his ears as if listening to a faint rumbling murmur far off in the wilds which might have been anything—even the mill of a forest god, grinding the grist of men’s destinies. But mostly he watched the two men.

Dugan produced a bottle, long hoarded, but Holliday would not touch it. He wanted to stay awake, he said, that no atom of his wonderful good luck should go untasted to the full. He would be starting downstream at daybreak. And Dugan grinned, and drank himself.

Holliday began to cook a festive meal. The smells were savory and delicious, but Cheechako’s nose suddenly attracted him to an unusual spot. He went tentatively toward Holliday’s bunk. Being a well-mannered dog, he knew he should never climb upon his master’s bed, but something drew him there irresistibly. He sniffed, and Dugan’s smell was suddenly that of a thing in deadly fear. Cheechako turned his head and regarded him puzzledly. Dugan’s scent was on his master’s blankets, too, and Dugan had no business to be there. Cheechako sniffed, bewildered. This other odor——

“There’s just one thing,” said Holliday with a sudden wistful gravity. “Old Sam’s dead. I told you how he was murdered. I wish—well, I wish he was going Outside with me.”

The faint rumbling outside that sounded like millstones grinding grew suddenly loud and harsh, as if the stones were crumbling up the last stray grains that had been fed to them. Cheechako cocked his ears, but that was only a noise. There was a queer smell on his master’s bunk. He heaved up his forepaws to sniff it more nearly.

“Cheechako!” snapped Dugan. Dugan had gone suddenly pale, and more than ever he had the smell of fear about him.

Holliday lifted his head and a curious expression came upon his face. Dugan went over and took Cheechako by the collar.

“Shedding fleas on your bunk,” he said to Holliday, grinning. “But he ought to share in the celebration, too. Got any molasses?”

He knew, of course. He reached up and took down the bottle of syrup Holliday had saved as a supreme luxury.

“Taught a dog to do this once,” grinned Dugan. “Here, you, Cheechako! Open your mouth!”
