It happened that the tall backwoodsman had a fancy for good fowls. He had several times sent away for settings of thoroughbred eggs; and having had good luck with them, he had now a very handsome and unusual flock to brag of. To be sure, Buff Cochins and Plymouth Rocks and White Leghorns and Black Minorcas all ran together, and the free mixture of breeds wrought strangely diversified results. But it was a great flock, for all its commingling, and accomplished wonders of egg-laying; and Jabe Smith took pride in having it well housed. The fowl-house was simple, but quite up to date in its pattern, which had been carefully copied from cuts in the Colonial Farmer. At each end of the long sunny front was a little entrance cut for the use of the “biddies,” and closed at night by a sliding drop door.

“Here, Jabe,” said the Boy, kicking one of these little doors with his toe, “is your trap!”

A gleam of instant comprehension flashed into the woodsman’s eyes, but he maintained a strategic silence.

“And yonder,” continued the speaker, with a wave of his hand toward the scattered flock, feeding, or scratching, or dusting feathers in the sun,—“is your bait.”

“How’s the bait goin’ to like it?” asked Jabe.

“Oh, the bait’s not going to mind!” said the Boy, cheerfully. “You just wait and see!”

The problem now was a simple one. The Boy knew that Red Fox had explored the premises thoroughly by night, outside, and would undoubtedly have explored them inside as well but for the fact that nightfall found the doors all closed. He argued that the shrewd animal was expecting to sometime find a door left open by mistake. Now was the time for that mistake to occur. In its simplicity and effectiveness the Boy’s plan commanded the backwoodsman’s instant acceptance.

Knocking together a little platform of light boards about three feet square, the Boy laid it on the floor just inside one of the small doors. From it he ran a cord up each side of the door, over two nails at the top, and joined them in the centre. Here he rigged a sensitive trigger catch connecting with the loop that held up the sliding door. The edge of the platform he raised about an inch from the floor, attaching it to the trigger in such a way that the slightest additional weight would spring the catch and let the door drop down. This accomplished, with the skilful aid of Jabe Smith and his tools, the Boy placed some tiny blocks under the platform to brace it up and prevent it being sprung prematurely by the hens as they passed out and in.

“Now, Jabe,” said the proud strategist as the two stood off and eyed their handiwork, “all you’ve got to do is wait till all the hens have gone to roost. Then shut the other door, and take out the props from under the platform. When Red Fox comes, as he’s likely to do just about moonrise, he’ll be much pleased to find that for once his enemy has forgotten and left a door open. He’ll slip right in to see what the hen-house is like inside. The door will drop,—and then you have him!”

“But what about the hens?” queried their owner, doubtfully.
