The yacht sailed on and Dick, walking up to Captain Wilson, who stood at the wheel, said, as he lifted his cap:

"I beg to report for duty, sir." The captain grinned, as he replied:

"I hope you'll always be as polite. You'll sure be a curiosity on this coast. I'll put you in with Pedro. He doesn't know much English, but you can talk enough for both. There he is, that black-mustached fellow, with little rings in his ears. He will let you know what your duties are."

A string of four dingies trailed behind the sponger and as many poles, each thirty feet long, with a sponge-hook at one end, lay upon the deck. Pedro was examining one of these poles when Billy went to him and said:

"Pedro, I am to go in your boat. What do I have to do?"

"You scull where I tell you—slow—I look in glass—see sponge—take up pole—you stop still—then you scull where pole go—you work good or I keek you."

"Pedro, if you ever keek me, you'll go overboard queek and don't you forget it."

The sponger lay at anchor on the sponging ground for nearly a week before the water was clear enough for work. Dick spent most of his time sculling his dingy and soon learned to throw his weight on the big sculling oar to the best advantage without going overboard very often. One day while Pedro sat in the bow, they saw a 400-pound loggerhead turtle lying asleep on the water. Pedro motioned to Dick to scull up to the turtle and when the dingy was within three feet of the creature he jumped on its back and seized the edge of its shell just behind the head, with both hands. Pedro's weight was so far aft on the turtle's deck that the bow pointed upward and the reptile's struggles only served to keep its head above water and thus carry the man comfortably on its back. Soon Pedro shifted his right hand to the tail-end of the turtle and thereafter navigated his living craft with ease. Dick sculled the dingy beside the turtle and, while trying to make fast the boat's painter around the creature, fell overboard. Pedro didn't know enough English to express his feelings fully, and so talked Spanish for a while. Dick thought he could get the rope around the turtle more easily if he stayed in the water, and he finally succeeded, though the reptile got one of the sleeves of his shirt while he was doing it. Then the boy and Pedro got into the boat and pulled the turtle beside it. In rolling the reptile aboard they shipped a lot of water and as the turtle dropped suddenly to the bottom of the dingy Dick fell backwards out of the boat. Pedro began to express himself in Spanish again, and, as the sponger was less than two hundred yards distant, Dick swam to it, leaving his companion to bail out the dingy and scull it to the big boat. The boat's tackle was required to hoist the turtle aboard, where it was turned over to the Cook, who butchered it on deck. The heart of the reptile continued to beat for hours after it had been removed from the body, so strongly that its throbbing could not be restrained by the grip of the most powerful hand. Pedro said that the heart would beat till the sun went down, and it did.

For days Dick hunted all the turtles he saw lying on the water. At last he got near enough to one to grab him before he dove. But he got hold too far back, the reptile's head was already turned downward and his flippers forced him rapidly forward. Dick hung on as well as he could, which wasn't for long, for the strong rush of the water and its great pressure as the reptile made for the bottom quickly compelled the boy to let go. Yet he was under water so long that when he came to the surface Captain Wilson was in a dingy sculling like mad to reach him. The captain gave the boy a kindly warning, which affected him so much that in ten minutes he was off after another turtle, which he saw asleep. The creature began his dive just as Dick jumped for him, and the boy got hold of his tail-end as it was lifted above the water, in time to get a sharp slap in the face from the heavy hind flipper of the turtle. Dick sculled for an hour without seeing another turtle, when, as he was returning to the boat and within a hundred yards of it, one rose beside the dingy so near that the boy was on its back before it could go under the surface. He soon had his charger in fair control, but the science of riding a big loggerhead turtle isn't picked up in a minute. One of the crew came out in a dingy to help, but Dick asked him to pick up his boat and oar and take them to the sponger and said that he would ride back on the turtle. Sometimes his steed was manageable, and once he got within a few yards of the big boat, when it broke loose and carried him fifty yards away. Then, as Dick tried to check the reptile, he pulled its head too far and tipped it over on its back on top of himself, with his own head so near the parrot-like jaws of the loggerhead that when they were snapped in his face they missed his nose by about an inch. The turtle was as anxious to turn over as the boy, and, by favoring his motions, Dick soon had the creature right side up, while he again rode triumphantly on his back. In another hour the halyards were fast to the turtle and Billy had made good his promise to ride it back to the boat.
