“How is it, Dave?” asked Hiram.

“I can’t tell exactly,” was the reply. “Some of the tubing is loose and the gear is out of center. With what tools we have and duplicate parts, we may be able to fix things up good enough to carry on to the South American coast.”

“Let’s do it, then,” suggested the eager Elmer. “Those other fellows may get the biggest kind of a lead on us while we are delaying here.”

“They are probably having troubles of their own,” remarked Dave. “It would be impossible to do anything in this fog. Besides, it will take us at least a day to repair the Comet. We might just as well take a resting spell and a bite to eat.”

The food supply aboard the biplane was abundant, but no attempt was made to cook a meal. The airship boys indulged in a lunch composed of crackers, cheese and some lemonade, in the manufacture of which beverage Hiram had become something of an expert.

“I say,” he suddenly exclaimed, ten minutes later, as he bolted a mouthful of cracker—“look there!”

The speaker pointed, and all hands arose to their feet. In the far distance a growing yellow glow began to diffuse itself over the western sky. As suddenly and completely as the dense fog had come down upon them earlier in the day, a grand clearing up transpired.

“Why, it’s just like the rolling up of a curtain,” cried Elmer.

The airship boys stood viewing a swift panorama. Vague shapes and outlines began to stand out before their vision. The blue sky showed to their left, the ocean at quite some distance. The sinking sun sent up its radiant beams and they made out that they were on an island.

Its rounding end was disclosed as they swept the scene with interested glances. Little patches of forest and grassy plain showed.
