"Got a shock did you?" laughed his chum. "That's an electrical fish. Their mystery to me lies in where they get the electricity with which they are charged. Even a small one like that contains enough to give a powerful shock."

The morning had been advancing rapidly as they walked and talked and the sun was shining down hot on their bare heads. Charley, justifying Chris' confidence in him, was quick to recognize the danger from its torrid rays.

He cast a look up at the sun. "It is nearly noon," he declared. "We must get something to cover our heads with and then find something to eat. I am getting as hungry as a wolf."

There was nothing along the rocky, muddy beach that would do for hats and the two bent their steps in towards the mainland. There, they broke off small leafy branches and thrust the stems down the backs of their shirts so that the leaves would tower above, and shade their heads. These made only a poor substitute for hats, but shed off the fiercest rays of the sun.

Close to where they broke off the boughs was a small running stream and the boys drank thankfully of its cold sweet water.

"We have no time to waste in cooking and I fear our bill-o-fare for dinner will be rather scanty," Charley said. "Let's look around here and see if we cannot find fruit of some kind."

There were palmetto berries in plenty all along the high bank but the lads had no desire to partake of them except in a case of necessity. Seeing nothing promising along the edge of the jungle, they scrambled up the bank and made their way slowly and cautiously into the hammock, keeping a wary eye out for snakes. They found fruit of several kinds in abundance, but most of it Charley rejected as being poisonous, or not fit to eat. They gathered two kinds which he declared were both palatable and nourishing. One was a golden-red fruit about the size of a pear. It contained a large nut to which the meat clung closely. One bite into it and the boys' hands and faces were smeared with sticky juice. "I would recognize that smeary juice and strong turpentine flavor, anywhere," laughed Walter, "these are mangoes, the fruit, they say, you have got to get into a bath-tub to eat if you want to keep clean."

The second fruit was about the size of a large plum and snow white in color with a blotch of red on the sides. Its meat was sweet, milky and slightly puckering.

"They are cocoa-plums," Charley explained. "They are considered quite nutritious but I would be afraid to eat a great many of them at a time on account of their puckerishness. We can eat all we want to of the mangoes however, they will not hurt us."
