The hounds followed Godfrey’s trail through the camp, and diving into the cane on the opposite side were quickly out of sight.  The boys followed, and presently stood panting and almost breathless beside the drift-wood where the hounds were running about close to the water’s edge, now and then looking toward the opposite shore and baying loudly.  But Godfrey was safely out of their reach.  Seizing the opportunity when the hunters and dogs were hidden from view in the cane, he stepped into the water and struck out for the mainland.  He had hardly time to climb the bank and conceal himself in the bushes before Don’s hounds were running about on the very spot where he had been hidden but a few minutes before.  Why was it that the hounds followed his trail as they would have followed that of a bear or deer?  Simply because they scented him before they reached the island, and because Godfrey took so much pains to keep out of their way.  Had he stood out in plain view while the boat was approaching, the hounds would have paid no attention to him.

“Well, he’s gone,” said Bert, and the deep sigh that escaped his lips as he uttered the words would have led one to believe that he was glad of it, “and now comes the hard work.  It’s an all-day’s job to build that trap.”

“It would be if we had to cut down the trees and trim off the branches,” replied David; “but there is some timber in this drift-wood that will answer our purpose as well as any we could get ourselves.  Where are you going to build the trap, Don?”

“In there where his den is would be the best place, wouldn’t it?  Now let’s go after the axes; and while you and Bert are cutting the logs, I’ll unload the boat and open a road through the cane, so that we can haul our timber in without any difficulty.”

The work being thus divided rapid progress was made.  By the time Don had unloaded the boat and cut a path leading from Godfrey’s camp to the upper end of the island, Bert and David had selected and notched all the logs that were needed for the trap.  Then a stout rope, which Don had been thoughtful enough to put into the boat, was brought into requisition, and the work of hauling in the logs began.  As fast as they were placed in position, Don fastened them down with the pins he and his brother had made the night before, and when lunch time came, a neat log cabin about six feet square was standing in front of Godfrey’s lean-to.  With a little “chinking” and the addition of a door and perhaps a window, it would have made a much more comfortable place of abode than the miserable bark structure which Godfrey had so long occupied.

Their hard work had given the boys glorious appetites, and they did full justice to the good things Mrs. Gordon had put up for them.  Don said their lunch might have been much improved by the addition of one of the ducks Bert had shot that morning, but their time was much too precious to be wasted in cooking.  The hardest part of their task was yet to be done, and that was to build a movable roof for their cabin.  Don, who had received explicit instructions from his father the night before, superintended this work, and by the middle of the afternoon the trap was completed and set, ready for the bear’s reception.
