“Do you think I would take that man for a woman with a perfect figure, such as you described? What in the world do you fancy is the matter with my eyes?”

“By gum!” drawled Gallup. “This air business is gittin’ too thick fer me. I don’t like so much mystery a bit.”

“If that man was not the one you meant, Hodge,” said Merry, “then the mysterious woman is still on this train.”

“That’s so,” nodded Bart.

“Find her,” urged Frank. “I want to get my eyes on her more than ever. Surely you should be able to find her.”

“I’ll do it!” cried Bart, jumping up.

Away he went.

Frank remained with Havener and Gallup, talking over the exciting and thrilling adventure and the mystery of it all till Hodge returned. At a glance Merry saw that his college friend had not been successful.

“Well,” he said, “did you find her?”

“No,” confessed Bart, looking crestfallen. “I went through the entire train, and I looked every passenger over. The woman I meant is not on this train.”
