A light breeze sprang up while they were eating, and when they made their departure from Swile Island Skipper Zeb hoisted a leg-o'-mutton sail, and then sat and smoked his pipe and told stories of experiences and adventures on the trail, while Toby took the rudder.

It was nearly three o'clock when Skipper Zeb pointed out a little log hut near the mouth of a small river, and announced:

"There's Black River and there's Black River tilt where we bides to-night."

A few minutes later the prow of the boat grounded upon a gravelly beach, and while Skipper Zeb unloaded the cargo the boys carried it to the tilt, laying it upon spruce boughs broken by Toby to protect it from the snow.

The tilt was built of logs, with a roof thatched with bark. The door was not more than four feet in height, and when Skipper Zeb opened it the three were compelled to stoop low to enter. The interior was a room about eight by ten feet in size. Across the end opposite the door was a bunk, and, along the right side of the room as they entered, another bunk extended from that at the far end to the wall behind the door. On the left side of the room, and midway between the end bunk and the door was a sheet-iron tent stove, with a pipe dismantled and lying on top of it. An old pair of snowshoes, and steel traps, pieces of board shaped for stretching pelts of various sizes and some simple cooking utensils hung upon wooden pegs against the wall. The floor was of hard-packed earth.

"Well, now! Here we be safe and sound and ready for work!" boomed Skipper Zeb. "Everything snug and fine when we gets our beds made and the stove set up and a fire in she. Whilst you lads gets boughs for the beds, I'll be puttin' up the stove and stow the cargo inside."

Toby and Charley went to work with a will, and soon had deep springy beds laid upon the bunks. Upon the bunk at the farther end they spread Skipper Zeb's sleeping bag, and side by side, upon the other bunk, their own. Already Skipper Zeb had a crackling fire in the stove and the cargo carried in and stowed snugly under the berths.

"Now whilst Toby and I tidy up a bit, put over the kettle, Charley lad, and we'll have a bite to eat," suggested Skipper Zeb.

Charley took the tin pail that served as a kettle, to fill it at the river. Just as he had dipped it and was about to return, his eye fell upon a peculiar looking animal perched upon a branch high up in a spruce tree. With all speed he ran back to the tilt and called excitedly upon Toby to come and see it.

"'Tis a porcupine!" exclaimed Toby, grabbing his rifle and following Charley. "I'll shoot he, and we'll have he for supper!"
