In a few seconds more Bob was again perched upon his companion's shoulders, and this time he was sure that his efforts would be crowned with success. The planks were fastened to the window casing, which, on one side, was too badly decayed to hold the spikes. He started some of them with the first pull he made at his lever, and, encouraged by his progress, was about to prepare for a greater effort, when Lester uttered an exclamation of alarm and jumped from under him.

“Great Moses!” exclaimed Bob, who came to the ground with fearful violence. “Do you want to kill a fellow?”

“No,” said Lester, whose voice trembled so that it was almost inaudible. “There's somebody coming!”

Before Bob could ask any more questions, a loud, shrill whistle, which sounded only a little distance away, rang through the quarters, followed almost immediately by the impatient yelp of a hound. The young prowlers were frightened almost out of their senses. Before they could make up their minds what ought to be done, a voice shouted:

“Here they be! Take 'em, fellers! Take 'em down!”

Another impatient yelp and the rush of feet on the hard road told the boys that Don Gordon's hounds were coming. This aroused them, and showed them the necessity of making an effort to escape. It was useless to run; the only place of safety was the roof of the cabin, and they made the most frantic efforts to reach it. They darted quickly around the corner of the building, sprang upon the porch and squirmed up the posts with the agility of monkeys. But with all their haste they did not have a second to spare. They had scarcely left the porch before the hounds bounded up the steps and a pair of gleaming jaws came together with a snap close to Lester's foot, which he drew out of the way just in time to escape being caught. Panting and almost breathless with terror the two boys crept cautiously up the roof—the moss-covered shingles were so slippery that it was all they could do to keep from sliding off among the hounds—and seating themselves on the ridge-pole looked at each other and at the savage brutes from which they had so narrowly escaped. Then they looked all around to find the person who had set the dogs upon them, but could see nothing of him.

“Where has he gone, I wonder?” said Lester, who was the first to speak.

“Haven't the least idea,” replied Bob.

“Who was it?”
