Only once during the late storm were wolves sighted. Near the evening of the second day, a band of three made its appearance, keeping in the distance, and following up the herd until it was corraled at the regular hour. While opening the ice, the boys had turned their horses loose among the cattle, and on leading them out of the corral, the trio of prowlers had crept up within a hundred yards. With a yell, the boys mounted and made a single dash at them, when the wolves turned, and in their hurried departure fairly threw up a cloud of snow. "That's what Mr. Quince means by that expression of his, 'running like a scared wolf,'" said Joel, as he reined in old Rowdy. "When will we put out the poison?" breathlessly inquired Dell, throwing his mount back on his haunches in halting. "Just as soon as they begin to hang around. Remind me, and we'll look for tracks around the corral in the morning. My, but they were beauties! How I would like to have one of their hides for a foot-rug!" "The first heavy snow that comes will bring them out of the sand hills," said Dell, as they rode home. "Mr. Paul said that hunger would make them attack cattle. Oh, if we could only poison all three!" Dell rambled on until they reached the stable. He treated his mind to visions of wealth, and robes, and furry overcoats. The wolves had located the corral, the winter had barely begun, but the boys were aware of the presence of an enemy. A complete circle of the corral was made the following morning. No tracks were visible, nor were any wolves sighted before thawing weather temporarily released the range from the present wintry grip. A fortnight of ideal winter followed, clear, crisp days and frosty nights, ushering in a general blizzard, which swept the plains from the British possessions to the Rio Grande, and left death and desolation in its pathway. Fortunately its harbingers threw its menace far in advance, affording the brothers ample time to reach the corral, which they did at a late evening hour. The day had been balmy and warm, the cattle came in, gorged from a wide circle over buffalo grass, the younger ones, as if instinctive of the coming storm and in gratitude of the shelter, even kicking up their heels on entering the gates. The boys had ample time to reach headquarters, much in doubt even then whether a storm would strike or pass away in blustering threats. It began at darkness, with a heavy fall of soft snow. Fully a foot had fallen by bedtime, and at midnight the blizzard struck, howling as if all the demons of night and storm were holding high carnival. Towards morning a creeping cold penetrated the shack, something unknown before, and awoke the boys, shivering in their blankets. It was near their hour for rising, and once a roaring fire warmed up the interior of the room, Joel took a peep without, but closed the door with a shudder.
