which had been following the Spray which was less provided with that sort of food. Fishes will always follow a foul ship. A barnacle-grown log adrift has the same attraction for deep-sea fishes. One of this little school of deserters was a dolphin that had followed the Spray about a thousand miles, and had been content to eat scraps of food thrown overboard from my table; for, having been wounded, it could not dart through the sea to prey on other fishes. I had become accustomed to seeing the dolphin, which I knew by its scars, and missed it whenever it took occasional excursions away from the sloop. One day, after it had been off some hours, it returned in company with three yellowtails, a sort of cousin to the dolphin. This little school kept together, except when in danger and when foraging about the sea. Their lives were often threatened by hungry sharks that came round the vessel, and more than once they had narrow escapes. Their mode of escape interested me greatly, and I passed hours watching them. They would dart away, each in a different direction, so that the wolf of the sea, the shark, pursuing one, would be led away from the others; then after a while they would all return and rendezvous under one side or the other of the sloop.
