They called it "sailing;" but it was merely rocking about in the pretty boat, called the "Trout-fly," which was moored on the bank of the brook. As the boys did not know how to swim, Dr. Gray never allowed them to unfasten the boat.

It was a lovely day. The hills were as blue as the sky, and the sky was as soft as a dream. What harm was there in having a little "sail" in that black and green "Trout-fly?" Preston thought they were doing a proper thing, and so they were; but the young passenger they took with them was soon to give them a world of trouble.

The boys had a pretty good time; but they could not make Flaxie talk: she said her "teef were tired." There was an anxious look on her face, and she never once smiled.

"What under the sun ails you?" said Preston, as she threw herself down in the bottom of the boat, with her head on his feet.

"I don' know," replied Flaxie; for she had no more remembrance of her dose of poison than a kitten has of its last saucer of cream.

"Are you sleepy?"

"No; but my eyes are."

"Let her go to sleep; don't bother her," said Jack Snow.

"Yes, I shall bother her too. She's real white; and I can't stand it," said Preston, stroking her cold cheeks in alarm.
