As for the point, an hour's rubbing on a piece of sand-stone made an excellent one.
It would be a matter of much time and labor to describe the appearance of the multitudes of fish that were day after day drawn into our boat by means of the brass hook. Peterkin always caught them,—for we observed that he derived much pleasure from fishing,—while Jack and I found ample amusement in looking on, also in gazing down at the coral groves, and in baiting the hook, Among the fish that we saw, but did not catch, were porpoises and sword-fish, whales and sharks.

We often saw them darting after other fish, and no doubt they sometimes killed them with their ivory swords. Jack remembered having heard once of a sword-fish attacking a ship,—which seemed strange indeed; but, as they are often in the habit of attacking whales, perhaps it mistook the ship for one.

I shall never forget my surprise the first day I saw one of these huge monsters close
