"I picked a rose in my garden fair—" sang Ada.

She sang without affectation. Her voice was a charming contralto, evidently partially trained, and promising with coming years to be worth consideration.

"But it withered in a day—" went on the lovely voice.

The girls were absolutely mute. When she had finished the song, and she gave it all, they burst into a spontaneous storm of applause.

Ada barely acknowledged the hand-clapping. Her face had instantly slipped back into the old sullen lines.

"When she can sing like that, shouldn't you think she would be perfectly happy?" sighed Betty. "I'd give anything if I had a voice!"

As a matter of fact Betty had a clear little contralto of her own and she sang as naturally as a bird. But there was no denying that Ada's voice was exceptional.

After the last girl had had her turn the veiled leader mounted the platform and threw back her swathing net.

"She's the president of the senior class, Mabel Waters," whispered a girl near Betty.

"I have the honor to welcome you all as members in good standing of the novice class, first-degree, Mysterious For," announced Miss Waters. "That's all there is to the name, girls—when we decided to form a new society here in school some one asked 'What's it for?' So our organization became the Mysterious F-O-R, and you'll find out as time goes on what the answer is. I might say, though, that happiness and good fellowship and a little spice of sisterliness are what we try to incorporate in the unwritten bylaws. And now I think Aunt Nancy has some cake and ice-cream for us."
