“Yes, let’s put one of the dynamite signs here,” exclaimed Helen.

“I wouldn’t,” interposed clever Cleo. “Perhaps the dynamite people don’t know anything about the star clue. We might lead them to it.”

“But it’s only a stone star,” insisted Helen.

“And it didn’t grow there,” argued Cleo.

“Look!” exclaimed Corene, who was critically examining the tiny strip of stone she had pried loose. “There are some figures or something marked on this.”

Everyone now crowded around her to see the characters.

“That is not Indian,” declared Miss Mackin. “It looks as if it were burned in with acid.”

She was scrutinizing the little flat mosaic-like block. Yes, there seemed to be a mark there, but it might easily have been on the stone before the star idea originated.

“I’m going to keep this piece, at any rate,” declared Corene. “Maybe it’s a real carved beetle, like the Egyptian Scarabus,” she ventured.

“Hardly,” replied the director. “Yet it is interesting and yours, Corey, as you dug it up.”
