palaces surpassing anything to be seen on the Rhine, and castles which had fallen into decay before civilization began at the mouth of the Nile.”

“Go to it!” laughed Carl. “Make it good and old while you’re about it!”

“On the island of Titicaca,” continued Glenn, “are marvels in architecture which make the wonders of Egypt look like thirty cents! There are massive fortifications perched on the sides of almost perpendicular cliffs, and even to-day there are large stones carefully balanced on the verge of precipices, ready to be pushed off at a moment’s notice and sent crashing down on the legions of an attacking foe.”

“Those old fellows must have been fighters!” commented Ben.

“They were fighters, all right!” Glenn went on. “They ruled all that part of the world until the Spaniards came. They were very superstitious, the sun being an object of worship. The Temple of the Sun, on the island of Titicaca, was one of the most magnificent structures ever erected. Outside and inside the walls were lined with gold and precious stones. The temple was the pride of the Incas, but it was stripped of its rich covering by the Spaniards. The walls were torn down and rifled, and the sacred sun was seized and gambled for by the covetous invaders. Nothing that could be converted into money was overlooked. And since that time the Incas have become one of the lowest races on the face of the earth.”

“I suppose we shall be able to inspect a lot of these old temples?” asked Carl.

“Undoubtedly!” Glenn answered. “Some of them are deserted; some are occupied by native Indians, and some are said to be frequented by the spirits of those who erected them.”

“Gee! That sounds good to me!” exclaimed Jimmie.

“A haunted temple might help some!” Carl exclaimed.

“There really is a temple down on Lake Titicaca!” declared Glenn, “which even Europeans declare to be inhabited by the Evil One.”

“That’s where I’m headed for!” declared Jimmie. “Any old time you show me a mystery you’ll see me on the job!”

“There’s a mystery there, all right!” Glenn insisted. “The temple stands on a winding arm of the lake, and is entirely surrounded by broken country. So difficult is it of access that for years no one attempted to visit it. Then, a few years ago, a party of Englishmen made their way to the ruins and found themselves in an atmosphere of mystery almost resembling magic.”

“What did they see?” asked Ben.

“I don’t remember exactly what they all saw,” Glenn answered. “Their stories do not agree! Some saw figures in white—the long flowing robes of priests—some saw strange lights suspended in the air; some heard the most mournful and terrifying sounds.”

“And these Englishmen were supposed to be people of average intelligence?” asked Ben.

“There were scientists in the party!” was the reply.

“There is no such word as ghost in the dictionary of the scientist!” laughed Carl.

“Following the stories told by the visitors,” Glenn went on, “a number of people visited the vicinity of the temple, and all came away with tales more vivid and more imaginative than those of the scientists. For two years now the place has been left entirely alone.”

“We might go there and camp!” suggested Carl.

“I move we take a look at it!” Jimmie cut in. “We can fly down on the roof and get away before the goblins get us.”

“I’m game for anything you boys decide on,” Glenn declared, “but my private opinion is
