He hastily helped his wife and little one on the back of the mare, mounted his own animal, and, with the pack-horse at the rear, moved along the timber on a rapid walk, continually peering off in the gloom, as though it was possible for him to see the Sioux, who certainly were at no great distance.
One fear troubled him: Suppose they should resort to the same artifice as he, and one of them appeal to the earth for evidence. He would be equally quick to discover the proximity of the fugitives, and with his sense of hearing trained to the finest point by many years' exercise, would locate the whites with unerring precision.
CHAPTER XV.
MISSING.
But there was no avoiding the risk. In silence the little party threaded their way along the margin of the prairie, listening for the sounds they dreaded to hear, and peering through the gloom for the forms they held in unspeakable fear. Not until they had progressed several hundred yards can it be said that the rancher breathed freely. Then he checked his pony, and those behind him did the same.
The next instant he was out of the saddle, with his ear once more against the cold earth.
Not the slightest sound reached him through this better conductor. If the Sioux horsemen were moving, they were too far off for the fact to be known. When first heard, they must have been close to the wood, on reaching which they undoubtedly dismounted and advanced on foot.
In that event, they must detect the footprints of the ponies in advance, and with their skill in trailing were certain to learn of the course taken by the whites. Then the pursuit would be resumed in earnest, and the perils would increase.
One possible remedy suggested itself, though there was no certainty of its success. The snow was now falling so fast that it promised to obliterate the footprints to that extent that they could not be followed in the dark. As it was, even the lynx eyes of the Sioux could avail them nothing. One of their number must be continually dismounting and using his hands to make sure they were not off the track. A half hour or more interval, and this resource would be taken from them by the descending snow.
