They discovered a rather strange thing when they arrived in Greenburg and entered the first store that dealt in ladies' apparel. Oh, yes, indeed! the proprietor had tam-o'-shanters of just the required shade, baby blue. The friends bought immediately for fear some of the other girls who had come to town would find these and buy the proprietor out.

And then, prone to the usual feminine frailty, they went "window shopping." And in every store seeking trade from the college girls they found the baby blue tam-o'-shanters.

"It's the most astonishing thing!" gasped Helen. "What do you suppose it means? Did you ever see so many caps of one kind and color in all your life?"

"It is amazing," agreed Ruth. Yet she was reflective.

Jennie began to laugh. "Wonder if the seniors are just helping out their friends among the tradespeople? It looks as though the storekeepers had bought a superabundance of baby blue caps and the seniors were putting it up to us to save the stores from bankruptcy."

Ruth, however, thought it must be something other than that. Was it that the storekeepers had been notified by the senior "powers that be" to be ready to supply a sudden large demand for tam-o'-shanters of that particular hue?

At least, one little Hebrew asked the three friends if they had already bought their tam-o'-shanters. "For vy, I haf a whole case of your class colors, ladies, that my poy iss opening."

"What class color?" demanded Helen, grumpily enough.

"Oh, Mees! A peau-ti-ful plue!"

"They're all doing it! They're all doing it!" murmured Jennie, staggering out of the "emporium." "This is going to affect my brain, girls. Did the seniors know the storekeepers had the tams in stock, or have the storekeepers been put wise by our elder sisters at Ardmore?"
