“Please pardon an old man’s fancy. I could not resist the temptation of polishing these up a bit. The very sight of them makes me envious. They are indeed a rare find. I have a guess as to what they are made of, but your friend the Curator will know.”

“So,” exclaimed Patsy, “they are the very dishes you found in the cave!”

“How very, very strange! We must have Mr. Cole come over at once,” said Marian, half beside herself with curiosity.

She raced to the telephone and a moment later had the Curator on the wire. If you have read our other book, “The Cruise of the O’Moo” you will remember that Marian, with her two friends, Lucile and Florence had once made a rare find for the Museum, so you will not wonder that so great a man should hurry right over in answer to their call.

When he arrived, Marian placed one of the bowls in his hand with the single comment: “From a cave in a mountain in Alaska.”

For three minutes he turned the bowl about before the light.

“What do you want me to tell you about it?” There was a strange light in his eye.

“Almost everything!” exclaimed Marian. “What it’s made of, who made it, how long ago, how—”

“Wait a bit. Not so fast!” the Curator held up a hand for silence.

“You should know what it’s made of,” he smiled. “What was the Blue God made of?”
