The girls stood close together on the edge of the water when the pup suddenly decided to run down to them. He bounded over the grass by the pool and before any one could follow his antics, he jumped in the pool among them.

The girls gave little shrieks and the pup thought it was a signal for play. He immediately caught hold of Zan's suit where it ended about the knee. His teeth felt like tiny steel pins as he clenched the edge of the material, and Zan might have frightened him off had he not upset her into the water. This done, he paddled about and heard the girls clapping madly at the prank. He thought this meant that they wanted some fun too, so he raced to their side and jumped about in the shallow pool, making them squeal and hug each other. The puppy would not be balked of his fun, however, so he tried to get a hold on their fitted suits.

Wild screams and laughter resulted, and suddenly, while the Guide stood under the willow holding her side breathlessly, the entire group, victims and dog, rolled over into the pool.

Of course, there was a mad scene of splashing, sputtering and crying out for help, before either of the girls could rise. The puppy stood on the edge of the bank wagging his tail, his head on one side with black eyes winking at his prey, and his tongue lolling from one side of his wide-open mouth.

When the submerged four could recover a normal state of breathing again, the puppy bent down and began lapping water in as unconcerned a manner as a puppy can assume.

"I wonder if he can swim?" called Zan, who still stood at a safe distance where the dog had ducked her.

"Most likely; he ought to teach the girls the correct method," replied Miss Miller.

Zan whistled and threw a stick down stream to tempt the dog, but he merely watched it float away, and then laid down in the sun to dry.

All the coaxing and chirruping had no effect on the sleepy pup, so the girls ceased their wiles and tried to swim in good style.

During supper, the puppy cried for something to eat, and a bowl of oatmeal left from breakfast, and some warm milk was given him.
