"Well, look here, if you're such sillies, you deserve——"

But at this most interesting point the loud clanging of the preparation-bell put a stop to any further argument. With one accord the girls jumped up, and fled back as fast as they could run in the direction of the school. Ulyth and Lizzie, at the risk of being late for evening call-over, gave the conspirators time to get well away before they ventured to follow.

"What's the meaning of all this?" queried Lizzie, as they scouted cautiously through the glade.

"I can't imagine. They're evidently doing something they oughtn't to, the young wretches! But they're keeping it very dark."

"We shall have to watch them."

"We must indeed," sighed Ulyth. "Lizzie, I loathe eavesdropping and anything that savours of underhand work, but what are we to do? Something is going wrong among the juniors, and for the sake of the school we've got to put it right if we possibly can. It's no use asking them their sweet secret, for they wouldn't tell us; and I'm afraid setting the monitresses on the track would only make things worse. If we can find out what they're doing, then we shall know our ground. I'm a Torch-bearer and you're a Fire-maker, and we must appeal to them to keep their Camp-fire vows. But we can't do that till we've some idea of which rule they're breaking. How can we say to them: 'I strongly suspect you're not being trustworthy'? We've got to prove our words."

"Prove them we will. We'll dodge about till we catch them in the act," agreed Lizzie.

To both the girls it was uncongenial though necessary work. As seniors and League officers they felt they owed a duty to the school, but that it would be far wiser to appeal privately to the juniors' sense of honour, and win them back to straight paths of their own free will, than to carry the matter to head-quarters. For the present, patience and tact must be their watchwords.

Several days went by, and nothing particular occurred. Either the younger girls were on their guard or they had suspended their activities. On Friday evening, however, as Ulyth was coming along the passage from practising, she accidentally cannonaded into half a dozen members of IV b who were standing near the boot cupboard. She evidently surprised them, for one and all they hastily popped their hands into their pockets. It was promptly done, but not so quickly as to prevent Ulyth from seeing that they were eating something.

"It's all right," gasped Bertha Halliwell, with apparent unconcern, in reply to Ulyth's apologies. "You nearly upset me, but I'm not fractured."
