"How far from the shore were the quarters?" asked Charley.
"I don't remember, if I ever knew; but why?"
"Well, it seems to me this island has grown up somewhat as the hair on your head does, in a shock. The large trees, as nearly as I can make out, think six feet or so to be a proper interval between themselves, and the small trees have disposed themselves to the best of their ability between the big ones; then all kinds of vines have grown up among the big and little trees, as if to make a sort of shrimp-net of the woods, and cane has grown up just to occupy any vacant spaces that might be left. It occurs to me that if we're to hunt anywhere except along shore for the old quarters, we'd best make up our minds to clear the island as we go."
"I say, Charley," said Jack, "if you were obliged to clear an acre of this growth with your own hands what would you do first?"
"I'd get a good axe, a grubbing hoe, some matches, and kindling wood; then I'd take a good look at the thicket; and then I'd take a long, long rest."
"Yes, I suppose you'd need it. But that isn't what I meant. Never mind that, however. Ned, I don't see why this isn't as good a place as any for our camp. There's a sort of bluff here, and we can clear away a place for our hut and get the hut built with less labor than it would take to find traces of negro quarters that were destroyed twelve or fifteen years ago."
"Yes, but how about water?"
"Well, I don't think it likely that we'd find any visible remains of a well in the other place, and if we did we'd have to dig it all out again. Why not dig here?"
After some discussion, and the examination of the shore for a short distance in each direction, this suggestion was adopted. The building of a shelter was easy work. It was necessary only to erect a framework of poles, to cut bushes and place them against the sides for walls, and to cover the whole with palmete leaves – that is to say, with the leaves of a species of dwarf palm which grows in that region in abundance. These leaves are known to persons at the North only in the form of palm-leaf fans. On the coast of South Carolina they grow in all the swamps and woodlands.
A little labor made a bunk for the boys to sleep upon, and while Ned and Charley filled it with long gray Spanish moss, Jack got dinner ready, first rowing out from shore and catching fish enough for that meal while his companions finished the house.
"Now," said Jack, when dinner was over and the boys had stretched themselves out for a rest, "it's nearly sunset, and we're all tired. We've got the best part of two kegs of water left, so I move that we don't begin digging our well till morning."
"Agreed," said the other boys, glad enough to be idle.
"Now, I've got something I want you to tell me about," said Jack. "Two things, in fact." With that, he went to the boat and looked about. Presently he came back and said:
"One of 'em's dried up. Here's the other."
He handed Ned a queer-looking fish, almost black, about eight inches long, very slender, and very singularly shaped.
"See," he said; "its jaw protrudes in so queer a way that I can't make out which side of the creature is top and which bottom. Turn either side you please up, and it looks as if you ought to turn the other up instead; and then the thing has a sort of match-lighter on top of his head, or on the bottom – I don't know which it is. Look."
He pointed to the creature's head. There was a flat, oval figure there, made by a ridge in the skin, and the flat space enclosed within this oval line was crossed diagonally by other ridges, arranged with perfect regularity. The whole looked something like the figure on the opposite page.
"Now, what I want to know," said Jack, "is what sort of fish this is, which side of him belongs on top, and what use he makes of this match-lighter."
"I'm afraid I can't help you much," said Ned. "A year ago I would have told you at once that the fish is a shark's pilot, so called because he follows ships as sharks do, and the sailors think he acts as a pilot for the sharks. But now I don't know what to call it."
"Why not?" asked Charley.
"Because I don't know. I've been reading up in the cyclopædias and natural histories and ichthyologies about our fishes down here, and have found out that whatever I know isn't so."
"Why, how's that?"
"Well, take the whiting, for example. When I began reading up to see if there was any sort of cousinship between him and the dolphin, I soon found that the whiting isn't a whiting at all, but I couldn't find out any thing else about him. The whiting described in the books is a sort of codfish's cousin, and he lives only at the North. Neither the pictures nor the descriptions of him at all resemble our whiting, so I don't know what sort of fish our whiting is. I only know that he isn't a whiting, and isn't the remotest relation to the dolphin, because he is a fish and has scales, while the dolphin is a cetacean."
"What's a cetacean?" asked Charley.
"A vertebrated, mammiferous marine animal."
"Well; go on; English all that."
"Well, whales, dolphins narwhals, and porpoises are the principal cetaceans. They are not fish, but marine animals, and they suckle their young."
"Well, that's news to me," said Charley.
"Now, then," said Jack, "if you two have finished your little side discussion, suppose we come back to the subject in hand. What do you know, Ned, about this fish that I have in my hand, and why don't you call him a shark's pilot now, as you say you did a year ago?"
"Why, because the books treat me the same way in his case that they do in the whiting's. They describe a shark's pilot which is as different from this as a whale is from a heifer calf, and so I don't know what to call this fellow. Did he make a fight when you caught him?"
"Indeed he did. I was sure I had a twenty-pound something or other on my hook, and when I pulled up this insignificant little creature, with the match box on his head, I was disgusted. I looked at him to see if he hadn't a steam-engine somewhere about him, because he pulled so hard, and that's what made me observe his match box and his curious up-side-down-itiveness."
"I say, Ned," said Charley, "why is it that our Southern fishes are so neglected in the books?"
"Well, I've asked myself that question, and the only answer I can think of is this: in the first place, there is no great commercial interest in fishing here as there is at the North; and then the natural history books and the cyclopædias are all written at the North or in Europe, and so there are thousands of curious fish down here which are not mentioned. There's the pin-cushion fish, for example. I can't find a trace of that curious creature in any of the books."
"What sort of thing is a pin-cushion fish?" asked Jack.
"He's simply a hollow sphere, a globular bag about twice the size of a walnut, and as round as a base ball."
"Half transparent, is he? Red, shaded off into white? with water inside of him, and pimples, like pin-heads, all over him, and eyes and mouth right on his fair rotundity, making him look like a picture of the full moon made into a human face?" asked Jack eagerly.
"Yes, that's the pin-cushion fish."
"I thought so. That's my other one," said Jack.
"What do you mean?" asked Ned.
"Why, that's the other thing I had to show you, but couldn't find. I caught him with the cast net."
"And kept him to show to me?" asked Ned.
"Yes, but he disappeared."
"Of course he did. He spat himself away."
"How's that?"
"Why, if you take a pin-cushion fish out of the water, and put him down on a board, he'll sit there looking like a judge for a little while; then he'll begin to spit, and when
