the
back of the camp, and when she heard laughter and the sound of loud
talking coming from the boathouse, which was, of course, on the very
shore of the lake, Bessie breathed a sigh of relief, since it seemed to
her that the fact that the other girls were there would greatly
increase Dolly's chance of escaping detection.

But instead of taking advantage of what Bessie regarded as a great
piece of luck, Dolly paused to listen to the sounds from the boathouse,
and then turned calmly and walked in its direction.

For a moment an unworthy suspicion crossed Bessie's mind.

"I wonder if she can be going to see them--to make up with them?"
Bessie asked herself.

But she answered her own question with an emphatic no almost as soon as
she had asked it. Dolly's anger the night before and that afternoon
had not been feigned.

As she neared the boathouse, Dolly moved very cautiously. Even though
she could see her, Bessie could not hear her, and she even had
difficulty in following Dolly's movements, for she had put on a dark
coat, and was an inconspicuous object in the darkness.

From the boathouse there now came the sound of music; a phonograph had
been started, and it was plain from the shuffling of feet that the
girls inside were dancing. Dolly crept closer and closer, until she
reached one of the windows. Even as she did it a sharp, shrill voice
cried out, and Bessie saw someone rush toward her from the darkness of
a clump of trees near the boathouse. It was a trap, after all! Bessie
rushed forward, but before she had taken more than a couple of steps,
and before, indeed, her assailant could reach her, Dolly had
accomplished her purpose.

Still running, Bessie saw her lift the basket she carried, and throw it
point-blank through the window, first taking off the cover. And then
the noise of the phonograph, the shout of Dolly's assailant, and all
the noises about the place were drowned in a chorus of shrill screams
of terror from inside the boathouse.

Bessie had never heard such a din. For the life of her she could not
guess what Dolly had done to produce such an effect, and she did not
stop to try. For the girl who had seen Dolly and rushed toward her,
although too late to stop her, had caught hold of Dolly and was
struggling to hold her.

Bessie rushed at her, however, and, so unexpected was her coming, that
the other girl let go of Dolly and turned to grapple with the rescuer.
That was just what Bessie w
