The trapper and his young companion belonged to an emigrant train which, a few weeks previous to the beginning of our story, had left St. Joseph for Sacramento, and they had ridden in advance of the wagons to select a camping ground for the night. This was a matter of no ordinary importance at that particular time, for during the last two days a band of Indians had been hovering upon the flanks of the train, and the guide knew that they were awaiting a favorable opportunity to swoop down upon it. Hitherto Silas had had an eye only to the comfort of the emigrants, and in picking out his camping grounds had selected places that were convenient to wood and water, and which afforded ample pasturage for the stock belonging to the train; but now he was called upon to provide for the safety of the people under his charge.

The road, at the point where the horsemen had halted, wound around the base of a rocky cliff, which arose for a hundred feet without a single break or crevice, and was barely wide enough to admit the passage of a single wagon. On the side opposite the cliff was a deep gorge, which seemed to extend down into the very bowels of the earth. It was here that the guide had decided to camp for the night. He carefully examined the ground, and a smile of satisfaction lighted up his face.

“This is the place we’ve been looking fur,” said he, dismounting from his horse and tying the animal to a neighboring tree. “Now I will go out an’ look around a little bit, an’ you can stay here till the wagons come up. You won’t be afeared if I leave you alone, will you?”

“Afraid?” repeated Julian. “Of course not. There’s nothing to be afraid of.”

“You may think differently afore you see the sun rise again,” replied the guide. “Now, when the train comes up tell the fellers to take half the wagons an’ block up the road, here at the end of the cliff, an’ to put the others at the lower end. Then we’ll be protected on all sides. The Injuns can’t come down the cliff to get at us, ’cause it’s too steep; an’ they can’t cross the gully nuther. They’ll have to come along the road; an’ when they try that we’ll get behind the wagons an’ fight ’em the best we know how. It’s risky business, too,” added Silas, pulling off his cap and digging his fingers into his head, “‘cause if they are too many fur us we won’t have no chance on airth to run. We’ll have to stay right here an’ die, the hul kit an’ bilin’ of us.”

Julian, who had never seen an Indian in war-paint or heard the whistle of a hostile bullet, was amazed at the trapper’s coolness and indifference. The bare thought of a fight with the savages was enough to cause him the most intense alarm, and yet here was Silas, who had more than once been a prisoner in the hands of the Indians, and who knew much better than Julian could imagine it, what the fate of the emigrants would be if their enemies proved too strong for them, apparently as much at his ease as though there had not been a hostile warrior within a thousand miles. The boy wondered at his courage and wished his friend could impart some of it to him, little dreaming how soon he would have need of it.

“Do you really think there is danger of an attack?” asked Julian, as soon as he could speak.

The trapper, who was in the act of untying a haunch of venison that was fastened behind his saddle, turned and looked curiously at his companion.

“Youngster,” said he, “if you should diskiver a cloud as black as midnight comin’ up over these mountains, an’ should see the lightnin’ a playin’ around the edges, an’ hear the thunder a grumblin’, what would you say?”

“That we were going to have a storm,” replied Julian.
