keel. This was a piece of tough wood, of the same length and width as the real keel, and about five inches deep. He made it of this depth because the boat would be thereby rendered not only much more safe, but more able to beat against the wind; which, in a sea where the trade-winds blow so long and so steadily in one direction, was a matter of great importance. This piece of wood was pegged very firmly to the keel; and we now launched our boat with the satisfaction of knowing that when the false keel should be scraped off we could easily put on another; whereas, should the real keel have been scraped away, we could not have renewed it without taking our boat to pieces, which Peterkin said made his "marrow quake to think upon."
The mast and sail answered excellently; and we now sailed about in the lagoon with great delight, and examined with much interest the appearance of our island from a distance. Also, we gazed into the depths of the water, and watched for hours the gambols of the curious and bright-colored fish among the corals and sea-weed. Peterkin also made a fishing line, and Jack constructed a number of hooks, some of which were very good, others remarkably bad. Some of these hooks were made of iron-wood, which did pretty well, the wood being extremely hard, and Jack made them very thick and large. Fish there are not particular. Some of the crooked bones in fish-heads also answered for this purpose pretty well. But that which formed our best and most serviceable hook was the brass finger-ring belonging to Jack. It gave him not a little trouble to manufacture it. First he cut it with the axe; then twisted it into the form of a hook. The barb took him several hours to cut. He did it by means of constant sawing with the broken penknife.
