As the barrels were filled, we closed them carefully, and rolled them away to the cool vaults at the back of our cave. Our good fortune, however, was not to end here. A day after the herring fishery was over, and the shoal had left our bay, a great number of seals appeared, attracted by the refuse of the herrings which we had thrown into the sea. Though I feared they would not be suitable for our table, we yet secured a score or two for the sake of their skins and fat. The skins we drew carefully off for harness and clothing, and the fat we boiled down for oil, which we put aside in casks for tanning, soap making, and burning in lamps. These occupations interfered for some time with our work at Rock House; but as soon as possible we again returned to our labor with renewed vigor. I had noticed that the salt crystals had for their base a species of gypsum, which I knew might be made of great service to us in our building operations as plaster. As an experiment, I broke off some pieces, and, after subjecting them to great heat, reduced them to powder. The plaster this formed with water was smooth and white, and as I had then no particular use to which I might put it, I plastered over some of the herring casks, that I might be perfectly certain that all air was excluded. The remainder of the casks I left as they were, for I presently intended to preserve their contents by smoking. To do this, the boys and I built a small hut of reeds and branches, and then we strung our herrings on lines across the roof. On the floor we lit a great fire of brushwood and moss, which threw out a dense smoke, curling in volumes round the fish, and they in a few days seemed perfectly cured. About a month after the appearance of the herrings, we were favored by a visit from other shoals of fish. Jack espied them first, and called to us that a lot of young whales were off the coast. We ran down and discovered the bay apparently swarming with great sturgeon, salmon and trout, all making for the mouth of Jackal River, that they might ascend it and deposit their spawn among the stones. Jack was delighted at his discovery. "Here are proper fish!" he exclaimed; "none of your paltry fry. How do you preserve these sorts of fish? Potted, salted or smoked?" "Not so fast," said I, "not so fast; tell me how they are to be caught, and I will tell you how they are to be cooked." "Oh! I'll catch them fast enough," he replied, and darted off to Rock House. While I was still puzzling my brains as to how I should set to work, he returned with his fishing apparatus in hand; a bow and arrow, and a ball of twine. At the arrowhead he had fastened a barbed spike, and had secured the arrow to the end of the string. Armed with this weapon, he advanced to the river's edge. His arrow flew from the bow, and, to my surprise, struck one of the largest fish in the side.
