It was a wild, desolate scene, the dull gray sky overhead, the black and white shading below. Mile on mile the picture unrolled to the horizon, the vista widening slowly as the light increased, bringing forth the details of barren, wind-swept ridges and shallow valleys choked with snow. Not a tree, not a shrub, not even a rock broke the dead monotony. All was loneliness and silence. The snow lay gleaming and untrampled, except as here and there a dull brown patch of dead grass darkened the side of a hill. Hamlin shadowed his eyes with gloved hands, studying intently inch by inch the wide domain. Suddenly he arose in his stirrups, bending eagerly forward. "By heaven! There they are, Hughes," he exclaimed, feeling the hot blood course through his veins. "See, on the incline of that third ridge. There is a shadow there, and they are not moving. Here; draw in back of me; now you can see. It looks as though they had a horse down." Hughes stared long in the direction indicated, his eyes narrowed into mere slits. "Ah! that's it," he said at last. "Horse broke a leg; shot it jest then--I seen the flash. Now they 're goin' on. See! One fellow climbin' up behind 'nother, an' the horse left lyin' thar on the snow." "How many people do you make out?" and Hamlin's voice shook a little. "There's four, ain't there?" At that distance the fugitives looked like mere black dots. It could scarcely be determined that they moved, and yet their outlines were distinct against the background of white snow, while the two watchers possessed the trained vision of the plains. Hughes answered after a deliberate inspection, without so much as turning his head. "Thar's four; leastwise thar was four hosses, and two--the Injuns likely--are ridin' double. Thar animals are 'bout played, it looks ter me--just able ter crawl. Ain't had no fodder is 'bout the size o' it. We ought to be able ter head thet bunch off 'fore they git to the Canadian at thet rate o' travel--hey, Sergeant?" Hamlin's eyes followed the long sweep of the cross-ridge, studying its trend, and the direction of the intervening valleys. Once down on the other slope all this extensive view would be hidden; they would have to ride blindly, guessing at the particular swale along which those others were advancing. To come to the summit again would surely expose them to those keen Indian eyes. They would be searching the trail ahead ceaselessly, noting every object along the crests of the ridges. However, if the passage around was not blocked with snow, they ought to attain the junction in ample time. With twice as far to travel, their ponies were strong and fit, and should win out against Le Fevre's starved beasts. He waved his gloved hand. "We 'll try it," he said shortly; "come on, Hughes."
