"That's so; how in the wide world could you know such a thing without ever seeing her?" demanded Toby.

"Nothing could be easier, fellows; see here!"

"Why, it's a comb," cried one.

"Only an old broken comb," echoed another, with a shade of uncertainty in his voice.

"What is there about that to tell you, Elmer?" queried Red, staring first at the article in question, and then at the smiling scout master.

"I know," burst out Matty just then.

"Tell us," pleaded several.

"Yes, throw some light on the dark mystery," added Lil Artha, "because to the untrained eye it's all as gloomy as the inside of my pocket. A comb, and how to tell a woman's age from that! Well, I own up beat."
