"Oh, it's a bit of a contrivance to stand over a hole in the ice where I propose to place a 'set' line for fish—that is, you know, a line that I bait and leave set for a while, trusting to luck to catch something. The minute a fish gets the hook through his lips and begins to flop around, he will set this flag a-fluttering and so let me know it. I might make him ring a little bell if I had one."

"I should say," Katy remarked laughingly, "that to make a captured and dying fish ring his own funeral knell was adding insult to injury."

At length Tug pulled on his overcoat and announced that he was going to look for a good fishing-place.

He was gone nearly an hour, during which Katy busied herself in mending her sadly torn dress, and in thinking. But the latter was by no means a pleasant occupation, and she was glad to see Tug come back, rubbing his ears, for the day was a cold one.

"I think I have found a real likely place for fishing," he told her. "There is a little cove the other side of this thicket, with a marsh around it, and a pretty narrow entrance. I reckon the water's deep enough in there for fish to be skulking, and I dropped my line right in the middle. I set the traps near here, but didn't see any birds."

"Do you think—" Katy stopped suddenly, laying one hand on Tug's arm, and holding up the other warningly, while her face grew pale. Rex, who had been lying by the stove quietly licking his injured paw, rose up and growled deeply.

"There! Did you not hear it?"

"I did. It's them pesky dogs," cried Tug, and hurried to the window, while Rex began to bark furiously. "There are the boys on the hill backing down, and two—no, three—dogs following them. Where's that axe? I'll fix 'em!"

And before Katy could quite understand what was the matter, the boy had burst out, and was tearing up the hill to the support of his friends. Rex wanted to go too, but Katy held him fast, as she stood watching the boys flourishing their weapons, and frightening the dogs back, while they slowly retreated. As they came nearer to the house the animals ceased pursuing, and relieved their disappointment by savage barks and prolonged howls.

"Well," exclaimed Tug, in the country speech he always used when excited, "I allow them curs are the most or'nary critters I ever see!"
