More little boats going down, and still nothing going up. Men said gloomily:

"We're done for! The fellows who go by the Canadian route will get everything. The Dawson season will be half over before we're in the field—if we ever are!"

The 28th of May! Still no steamer had come, but the mosquitoes had—bloodthirsty beyond any the temperate climates know. It was clear that some catastrophe had befallen the Woodworth boats. And Nig had been lured away by his quondam master! No, they had not gone back to the gulch—that was too easy. The man had a mind to keep the dog, and, since he was not allowed to buy him, he would do the other thing.

He had not been gone an hour, rumour said—had taken a scow and provisions, and dropped down the river. Utterly desperate, the Boy seized his new Nulato gun and somebody else's canoe. Without so much as inquiring whose, he shot down the swift current after the dog-thief. He roared back to the remonstrating Colonel that he didn't care if an up-river steamer did come while he was gone—he was goin' gunnin'.

At the same time he shared the now general opinion that a Lower River boat would reach them first, and he was only going to meet her, meting justice by the way.

He had gone safely more than ten miles down, when suddenly, as he was passing an island, he stood up in his boat, balanced himself, and cocked his gun.

Down there, on the left, a man was standing knee-deep in the water, trying to free his boat from a fallen tree; a Siwash dog watched him from the bank.

The Boy whistled. The dog threw up his nose, yapped and whined. The man had turned sharply, saw his enemy and the levelled gun. He jumped into the boat, but she was filling while he bailed; the dog ran along the island, howling fit to raise the dead. When he was a little above the Boy's boat he plunged into the river. Nig was a good swimmer, but the current here would tax the best. The Boy found himself so occupied with saving Nig from a watery grave, while he kept the canoe from capsizing, that he forgot all about the thief till a turn in the river shut him out of sight.

The canoe was moored, and while trying to restrain Nig's dripping caresses, his master looked up, and saw something queer off there, above the tops of the cottonwoods. As he looked he forgot the dog—forgot everything in earth or heaven except that narrow cloud wavering along the sky. He sat immovable in the round-shouldered attitude learned in pulling a hand-sled against a gale from the Pole. If you are moderately excited you may start, but there is an excitement that "nails you."

Nig shook his wolf's coat and sprayed the water far and wide, made little joyful noises, and licked the face that was so still. But his master, like a man of stone, stared at that long gray pennon in the sky. If it isn't a steamer, what is it? Like an echo out of some lesson he had learned and long forgot, "Up-bound boats don't run the channel: they have to hunt for easy water." Suddenly he leaped up. The canoe tipped, and Nig went a second time into the water. Well for him that they were near the shore; he could jump in without help this time. No hand held out, no eye for him. His master had dragged the painter free, seized the oars, and, saying harshly, "Lie down, you black devil!" he pulled back against the current with every ounce he had in him. For the gray pennon was going round the other side of the island, and the Boy was losing the boat to Dawson.
