The boys' eyes followed his pointing finger. Not far offshore were the vague outlines of a schooner.

"All black!" said Jim. "Not a light of any sort! That looks bad. Besides being against the law, it shows there's some reason why they don't want to be recognized. I don't know what kind of scalawags we're up against, but we've got to be mighty careful."

Percy felt a strange sinking at the pit of his stomach. To be plunged into an encounter with a gang of unknown ruffians on his first night offshore was more than he had bargained for. For a minute Jim stood thinking.

"I'm almost sorry we didn't take that shot-gun!" he muttered. "No, I'm not, either! We might be tempted to use it, and that'd be worse than losing every sheep on the island. Hold on! I've got an idea."

The boys gathered closely round him.

"Listen!" he whispered. "Budge and I will go ahead through the woods to the pasture. You three follow close behind. If there's any shooting, throw yourselves flat. No use taking chances with such fellows as those!"

Crouching low, sometimes actually creeping, the party, Jim and Lane in the lead, made their way under the close boughs toward the open. Suddenly Jim sank to the ground. Warned by his whisper, the others did the same.

Footsteps were approaching. Then voices in heated argument reached their ears.

"Aw, come on, Cap!" expostulated one unseen speaker. "What's the use chasin' round over this pasture all night? Here we've wasted an hour already. I've fired away all my cartridges, and we haven't nailed a single bleater. We've got 'em so wild we can't sneak up within half a mile of 'em. Let's quit it for a bad job, go aboard, and turn in!"

"Cut it out, Dolph!" impatiently retorted another voice. "You've got a backbone like a rope! Guess if you were footing the grub bill aboard the Silicon you wouldn't be so fussy about being broken of your beauty sleep. I've paid out all the good dollars for stores that I intend to on this trip. You know we've plenty of ice aboard, and a couple of these sheep'll furnish enough fresh meat to last us to the Bay of Fundy and back. That ought to hit you in a tender spot. You're always the first man down at the table and the last to leave it."
