When his wood was gathered, Bobby with much effort dragged the boat to the rock, and then working hard and fast cleared away the snow as best he could with the aid of sticks and feet from the smooth rock bed in front of the bowlder, and on which the bowlder rested. He now carried from the innumerable stones lying about upon the wind-swept rocks, sufficient to build at right angles to the bowlder two rough walls about two feet high and as long as the width of the boat. These walls were perhaps eight feet apart, and when they were finished he raised the boat, bottom up, upon them, the after part of the boat resting upon one, the prow extending over the other, and the side of the boat shoved back flush against the bowlder face.
