From the fields where they saw the natives at work, our friends proceeded on their ride. Sometimes they were in the open country, and then in the forest; and as they rode along, their guide called their attention to many things of interest. The forest was rich and luxuriant, and sometimes the vines and creepers were so numerous that it was difficult to proceed. There were pitcher-plants hanging from the trees, and two or three times the excursionists drank from them to slake their thirst. A wild boar was roused from his lair, but, as the party was unprovided with hunting weapons, he was not pursued, and the same was the case with a deer that came bounding across their path. In one part of the forest several wild monkeys chattered from the tops of the trees, and made grimaces at the intruders; but they were not otherwise disturbed than by the presence of the strangers.
They came at length to the shore of the lake, and dismounted. The boys suggested that a bath in the tepid water would be agreeable; but their guide shook his head very impressively, and remarked that their lives would not be worth much after they took their first plunge.
"Why so?" inquired one of the boys.
"Because," was the reply, "the lake swarms with crocodiles, and you would be in the jaws of one of them before you could swim a dozen yards."
As he spoke, he pointed to a dark object on the surface of the water a hundred yards or so from shore. At first glance it appeared like a log of wood, and so the strangers would have considered it but for the special direction they had received.
The boys regarded it a few moments with great attention, and then Fred cried out,
"I believe it's the head of a crocodile!"
"And I, too," said Frank. "Perhaps he'd like to have us take a bath here; but we won't do anything of the kind."
"It is quite unsafe to bathe here," said Mr. Segovia, "and after what you have seen you are not likely to venture; but we will mount our horses, and ride a few miles back from the lake to where there is a pretty cascade with a fine pool below it; there you may have a bath without the least danger."
