“We might have known it,” cried Nancy Brown savagely. “If Billie Campbell hadn’t owned a motor car, Belle Rogers would never have given herself the trouble even to speak to her.”

You perhaps know what a dangerous quality snobbishness is in a girl’s school. A very little of it is like a drop of strong poison in a pail of water. It pollutes the whole pail. So it was at West Haven High School. Belle Rogers, the prettiest and richest girl in town, had picked out six more or less wealthy and intimate friends in the sophomore class and constituted herself leader of what they called “The Mystic Seven.” These seven girls held themselves aloof from the poorer girls in the class and committed the unpardonable sin of snubbing every girl outside their charmed circle.

Very bitter were the feelings of the other ten sophomores against the “Mystic Seven,” who refused to mingle in the sports of the class and kept themselves apart at recess, talking in low, mysterious voices and laughing behind their pocket handkerchiefs when the other girls strolled by.

“They always make me feel shabbier than I really am,” Mary Price had once said.

And now the “Mystic Seven” had snatched up this nice, athletic-looking, new sophomore, whom many of them remembered as a bright, romping little girl years before.

“I suppose they’ll have to call themselves ‘The Mystic Eight’ now,” said one of the girls, a little bitterly.

“Can’t we ask her to join the ‘Blue Birds’?” put in Elinor Butler, who was eligible in point of wealth to enter the richer society, but had coldly declined the honor and had formed a society herself, called the “Blue Birds.”

“She couldn’t belong to both clubs,” said Nancy, “and you may be sure she has accepted the invitation of that little golden-haired, blue-eyed Belle Rogers, who put on an extra soft pedal even to call out her name.”

“Well, Billie Campbell will probably never have cause to know that Belle’s tongue is sharper than a serpent’s tooth, so what’s the odds,” observed Mary Price philosophically. “We got on perfectly well before she came and I suppose we can manage to support life pretty comfortably even if she is a member of the ‘Mystic Seven.’”

Her friends laughed, as they strolled by twos and threes into the broad, arched entrance leading into the corridor of the building. Mary Price often relieved their wounded feelings by ending discussions concerning the “Mystic Seven” with a joke, although not one of them had been cut more deeply than she herself by the cruel speeches of Belle Rogers and her friends; for, since the death of Captain Price, Mary Price and her mother, as you will see later, had had a hard struggle to make both ends meet.
