He had leaped from his bunk with a bound and made for his brother’s, Tom being the accepted leader of the Bungalow Boys.

“Close the shutters!” were the first orders Tom gave.

“What for?” Jack could not refrain from asking.

“So that no light can get outside” was Tom’s reply, “while we jump into some clothes and see what’s up.”

The shutters he referred to were used when an unusually heavy wind came up. They were felt lined and excluded every bitter draft. At such times ventilation was obtained from a device in the roof of the cabin. Jack soon had the solid blinds closed and fastened, and then he struck a match and lit the hanging lamp. The next task was to arouse Sandy while they hastily dressed. The Scotch lad was hard to awaken, but at length he sat up blinking and drowsy, and Tom rapidly informed him of what Jack had heard.

“Huh! I’ll bet it was nothing but just a wolverine,” spoke Sandy scornfully.

Wolverines, the gluttons of the northland, had assailed the fox pens quite frequently, being attracted by the odor of fish. In one instance the black fox’s pen had been almost demolished by the steel-clawed, truculent robber of the northern woods.

“Maybe that’s what it was,” said Jack anxiously, inwardly much relieved. As a matter of fact he had not much relished the notion of creeping out into the night upon possible human intruders.

“Well, if it is wolverines, we’ll have a chance to nail them red-handed,” said Tom, “so get a move on and jump into your ‘parkee’.”

Sandy saw from Tom’s face that there was no use delaying any longer and he lost no time in obeying. Then, armed with rifles, having carefully extinguished the light, the boys crept softly out into the night.
