"Not a bit, for there was nothin' to fall on but snow. He picked himself up, looked carefully at his snow-shoes to see that they had not been damaged, an' resumed his place at the head of the dogs. What would have become of him if he had been plucked into the middle of the whirlwind is hard to say. I wouldn't have counted on seein' him again anyway."

"But you never really got caught by any?"

"Wouldn't be here talkin', if I had," was the reply. "But when we come to the track of that whirlwind column, it was a puzzle how to get across. The column, goin' like a railroad train, had cut a gully in the hard snow full ten feet deep,—the sides as clean cut as though done with a knife, or rather with a scoop, because the edge was slightly scolloped all the way along."

"How did you get across?"

"Axes," was the brief reply. "We cut through the snow crust and beat down a steep path on both sides of the gully an' made the dogs take it. Dog harness is strong, but I was afraid of the strain on it that time."

"How long did the blizzard last?"

"You mean the whirlwinds?"

"Yes, sir," the boy answered.

"Not very long,—quarter of an hour, perhaps. Then I felt a slight breeze, an' at the same moment the columns, bendin' their heads like grass before the wind, swept to the right of us, an' were out of sight in a moment. The Indian yelled and pointed to the left, throwin' himself on the ground as he did so."

"What was it?" cried Hamilton.
