The cause of this excessive humidity was soon learned. In one corner of a second chamber was a boiling spring, which bubbled and hissed just below the surface of the floor.

He dipped his hand in, but immediately withdrew it as he gave vent to a cry of pain. The water was boiling hot!

This cavern also had an exit or outlet about forty feet long, which opened into a third, nearly twice as large as the first. From the roof hung hundreds of stalactites, some only a few feet in length and others which descended to the floor. Stalagmites glittered and glistened like immense diamonds in a strong phosphorescent light, until the radiations and reflections lent such an indescribable charm to the cave that it seemed as if one were living through a story from the “Arabian Nights.” This third room was evidently the end of the chain of caverns. In it there was no opening, yet the glow from the middle apartment filled it with light.

Wandering from one point to another without thought of weariness because of the many wondrous beauties, Philip soon began to realize the fact that he was hungry, and when on the point of retreating to the grotto where the bananas were, he bethought himself of the trout. To boil two or three in this kettle formed by nature would be comparatively an easy task, and at the same time give him a change of diet.

Passing rapidly on to the stream where he had seen the fish, he caught and dressed four, fastening them together with a strip torn from his handkerchief. Returning to the spring he lowered them, and in a few moments had sufficient and appetizing food for a hearty meal. Although eaten without salt, this change in his bill of fare was a welcome one, and Philip resolved to take with him a supply of cooked fish large enough to satisfy his wants during several days.

To this end he groped about once more on the bed of the stream until his hand came in contact with a very heavy round substance, which, simply through idle curiosity, he raised to the surface.

His astonishment can hardly be described when he discovered that the supposed rock was apparently a nugget of pure gold, weighing, as nearly as he could judge, from three to four pounds.

The sight of this wealth, which was also evidence that more might be found in the vicinity, so bewildered him that it was several moments before he could make further examinations, and then came the fever for riches which has been at the same time the destruction and delight of thousands.

Working with desperate energy, as if the unlimited time at his disposal was all too short for the purpose, he brought up nugget after nugget, ranging in size from an ounce to half a pound, until he had collected at least ten pounds’ weight of the precious metal.
