He sat in his nest picking the buds off the willow twigs, and bending and lacing them together, furtively glancing at grubby-looking Bob Dimsted, whose appearance was not attractive; but what were appearances to a boy who possessed such gifts of knowledge in fishing and managing a boat, and had learned so much about foreign lands?

Dexter sighed again, and Bob gave him a furtive look, as with evident enjoyment he took a red worm out of some moss and stuck his sharp hook into it, drew the writhing creature over the shank, and then passed the point through again and again.

So to speak, he had impaled Dexter on a moral hook as well, the barb had gone right in so that it could not be drawn out without tearing; and Dexter writhed and twined, and felt as if he would have given anything to get away.

Bob went on fishing, throwing the twisting worm just down among the roots of a willow-tree, and the float told directly after that the cast was not without avail, for there was a quick bobbing movement, then a sharp snatch, Bob struck, and, after a good deal of rushing about and splashing, a good-sized perch was landed, with its sharp back fin erect, and its gilded sides, with their black markings, glistening in the sunshine.

“What a beauty!” cried Dexter enthusiastically, as for the moment the wonders of the boating expedition were forgotten.

But they were brought back directly.

“Pooh!” exclaimed Bob contemptuously. “That’s nothing; only a little perch. Why, if we went off fishing in that boat, you’d chuck a fish like that in again.”

But Bob did not “chuck” that perch in again; he placed it in his basket, and directly after caught up his various articles of fishing-gear and ran off.

Dexter was about to speak, but just then he heard a harsh cough, and, glancing through the screen of willow twigs which surrounded him, he saw old Dan’l coming hastily down over the grass path towards the tree.

“Yes, I can see yer,” he shouted, as he reached the water’s edge; and, to Dexter’s surprise, he found that it was not he the old gardener was addressing. “You come over there fishing again, I’ll send the police arter yer.”
