"Speaking of sharks," remarked the Pilot, as he and his companion glided easily through the water, "many unjust things have been said about me because I am sometimes seen with the White Shark. They say a fish is always known by the company he keeps, but I think it is very unfair to judge me in that way, particularly as I never stayed with the shark because I liked him. I knew him for a heartless and ferocious monster who would attack anything that came in his way, and I was a good deal afraid of him. I only went with him as a matter of convenience to myself. But it was commonly supposed that I accompanied him as a guide in order to show him the best feeding places, and tell him what dangers to avoid, and that was how I got my name of the Pilot-Fish. But the real reason was that I got better food when in company with the White Shark than any other way. "Our usual plan was to follow some ship, which we often did for weeks, or months at a time, for a great deal of nice fish food is always thrown overboard from vessels; and as the White Shark only cared for the big pieces, all the tender little morsels fell to my lot. I lived well in those days, but I had to give up the job after awhile, the nervous strain was too great. "You see the White Shark that I was with then was a very big fellow, (fully thirty feet long), and just as strong and ugly as he was big. Once, down in the tropics where he usually lives, I saw him break a man's leg with one stroke of his tail. His temper was awful, and he would stop at nothing when angry. He had enormous jaws, with six rows of flat teeth, and to see him turn on his side, and open those jaws was enough to give you cold chills for a week. "The good food that we got from our ship usually kept the White Shark in a fairly good humor, but, knowing him as I did, I was well aware that if the food should happen to run short, he would not hesitate to make a meal off of me; and although I am an excellent swimmer, and stood a good chance of being able to escape (else I should have never been there at all), still there was always a possibility of something unpleasant happening, and it got to be rather wearing. "So, one day when we were following a particularly promising vessel, I made an excuse to stay behind, while the White Shark went on alone, and when he and the ship were both out of sight, I took the opportunity to escape. Since then I have carefully avoided the society of all sharks, but what I have learned about them and their ways has been of great benefit to me, and will be a help to us now, since they prefer the warm waters of the tropics, and that is where we are bound. However, you may trust me to keep as far out of their course as possible. "We will need to keep a sharp lookout for the Blue Shark, whom you have already had the pleasure of meeting, and we may catch a glimpse of the Hammer-headed Shark, a terribly fierce monster with a head shaped like a hammer.
