In order to advance with the least danger of being seen Tom had made a wide detour to gain the shelter of a stack of lobster-pots, with no idea in mind that there was any necessity for moving rapidly. But suddenly he heard the voice of Captain Doak, raised high as if in anger.

"Now there will be a row, an' if we don't take a hand Uncle Ben is bound to get the worst of it!" Sam cried, as he urged Tom forward by gripping his arm firmly. "Come on! We've got to help Uncle Ben!"

His own fears were forgotten in the desire to aid the old man who had been so kind to him.

The boys arrived on the scene at the exact moment when their services were most needed by Uncle Ben, for the master of the "Sally D.," apparently half crazed by anger, was rushing toward the lobster catcher with clenched fists.

"I reckon here's where we get our work in!" Tom cried, as if delighted by the evidences of trouble, and catching up the first missile that came to his hand, which proved to be a lobster-pot buoy, with a half-inch rope made fast to one end, he ran between the two men, swinging the heavy weapon in a threatening manner.

So blinded by his rage was Captain Doak that he apparently did not see the newcomers until Sam, armed with a heavy stake, pressed close by the side of his friend, and then, suddenly recognizing the truant cook, the commander of the "Sally D." sprang forward to seize him.

"None of that, or I'll let this 'ere buoy come agin your head!" Tom cried threateningly. He swung his improvised weapon yet more vigorously, and Captain Doak fell back a few paces, for a single blow from the heavy missile would have inflicted a serious wound.

"Why didn't you stay in the bushes?" Uncle Ben asked sharply of Sam, and before the latter could reply Captain Doak shouted:

"Get aboard the schooner, you young idler, an' when I've settled with this Ben Johnson I'll 'tend to your case in sich a way that you won't try to give me the slip ag'in!"

"He'll stay where he is! An' if you raise your hand against him we'll see what the law can do toward makin' you pay over to the lad the money what belongs to him from the sellin' of his mother's house!" Uncle Ben cried, as he pulled Sam toward him, at the same time looking in bewilderment at Tom, as if wondering where he had dropped from.
