"Better leave the blankets on," remarked the young officer. "They'll need 'em for warmth."
The sergeant saluted and continued his work, deft and silent, while Curtis threw up a little tent on a cleared spot and banked it snugly with snow. In a very short time a fire was blazing and some coffee boiling. The two men seemed not to regard the cold or the falling night, except in so far as the wind threatened the horses.
"It's hard luck on them," remarked Curtis, as they were finishing their coffee in the tent; "but it is unavoidable. I don't think it safe to try to go down that slide in the dusk. Do you?"
"It's dangerous at any time, sir, and with our horses weak as they are, it sure would be taking chances."
"We'll make Tom Skinner's by noon to-morrow, and be out of the snow, probably." The young soldier put down his tin cup and drew a map from his pocket. "Hold a light, sergeant; I want to make some notes before I forget them."
While the sergeant held a candle for him, Curtis rapidly traced with a soft pencil a few rough lines upon the map. "That settles that water-shed question;" he pointed with his pencil. "Here is the dividing wall, not over there where Lieutenant Crombie drew it. Nothing is more deceptive than the relative heights of ranges. Well, now take a last look at the horses," he said, putting away his pencil, "and I'll unroll our blankets."
As they crawled into their snug sleeping-bags Curtis said again, with a sigh, "I'm sorry for the ponies."
"They'll be all right now, Captain; they've got something in their stomachs. If a cayuse has any fuel in him he's like an engine—he'll keep warm," and so silence fell on them, and in the valley the cold deepened till the rocks and the trees cried out in the rigor of their resistance.
The sun was filling the sky with an all-pervading crimson-and-orange mist when the sergeant crawled out of his snug nest and started a fire. The air was perfectly still, but the frost gripped each limb with benumbing fury. The horses, with blankets awry, stood huddled close together in the shelter of the pines not far away. As the sergeant appeared they whinnied to express their dependence upon him, and when the sun rose they turned their broadsides to it gratefully.
The two men, with swift, unhesitating action, set to work to break camp. In half an hour the tent was folded and packed, the horses saddled, and then, lustily singing, Curtis led the way down upon the floor of the second basin, which narrowed towards the north into a deep and wooded valley leading to the plains. The grasp of winter weakened as they descended; December became October. The snow thinned, the streams sang clear, and considerably before noon the little train of worn and hungry horses came out upon the grassy shore of a small lake to bask in genial sunshine. From this point the road to Skinner's was smooth and easy, and quite untouched of snow.
