"I can't tell—-I can't see yet," answered her husband, turning anxious eyes from the musket he was hastily loading toward the cloud of dust. "But whatever it is, it is coming this way. It might be a herd of elk or buffalo, but anyway, we must be prepared. Get inside, Hannah, and thee and the little ones keep well under cover."

In the other wagon two younger boys had joined the lad who was driving. On the seat beside him now sat a merry-faced, brown-eyed lad of fourteen, and leaning on their shoulders peering out between them was a boy of twelve, the twin of the twelve-year-old girl in the other wagon, with red hair, laughing blue eyes, and a round, freckled face.

Sam was the mischief of the family, and was generally larking and laughing, but now his face looked rather pale beneath its coat of tan and freckles, and the eyes which he fastened on the horizon had in them an expression of terror.

"Do you suppose it's Indians, Joe?" he whispered huskily. "Did you hear what that man told Father at Fort Dodge the other day? He said that Indians had set on an emigrant train near Fontanelle and murdered the whole party."

The boy on the driver's seat did not answer. With his wide grey eyes focused intently on the cloud of dust in the distance, his tanned face strained and set, he craned forward, every muscle of his body at rigid attention.

Presently he handed the lines to the brother who sat beside him and reaching up into the curving top of the wagon took down a heavy old muzzle-loading musket.

"Do you think it is Indians?" the boy asked, his hands a bit tremulous on the lines.

"I dunno. Can't tell yet. But we've got to be ready anyhow. Better load up your rifle, Lige."

The brown-eyed boy wound the lines around the whip-stock and took from a rack under the cover a long-barreled rifle.

They had seen many roving bands of Indians on their journey, but had never been molested by them, but at the last settlement they had passed through they had heard horrifying accounts of the scalping and massacre of settlers and emigrants by the red men. On the old Overland Trail between Fort Laramie and the South Fork of the Platte there had occurred an Indian uprising a few days before, the terrifying news of which had reached them at their last stopping place.
