Casting his eyes about the cabin, he suddenly became aware of a small door in the bulkhead at the forward end of it. Curious by nature, Tubby opened it, and peered into a dark, cavernous space. A strong odor of gasoline saluted his nostrils, and presently--his eyes becoming used to the light--he could make out the occasional glint of metal. In a flash he realized that this was the engine-room of the sloop, and housed her auxiliary motor.
A button-switch being made out by the boy at this moment, he turned it. Instantly two incandescent lights shone out, illuminating the place. By their light Tubby made out another door beyond the motor. Determined to investigate the sloop thoroughly--come what might--he thrust it open, and found himself in what seemed to be the hold. But it was too dark to perceive much. Besides, the sloop was pitching and rolling so terribly that the lad had all he could do to hold on.
Returning to the engine-room, he almost stumbled across an electric torch secured to a bracket on the bulkhead. It was evidently used for examining the motor without exposing an open light to the fumes of the gasoline. Armed with this, Tubby once more investigated the hold. It was a capacious place. Stanchions, like a forest of bare trees, supported the deck above. So far as the boy could make out, the place was empty. Far forward was a ladder leading up to a hatchway. Tubby, following out his naturally inquiring bent of mind, was about to examine this, when his heart gave a great bound and then stood still.
He had not thought to cast a glance behind him in his eagerness to examine the hold.
This had proved to be a fatal bit of oversight on his part, for Stonington Hunt and his son, descending to the cabin for some purpose, had observed his absence. A brief investigation showed them the open door into the engine-room and thence they had glimpsed the flash of Tubby's torch.
The boy turned, warned by some instinct, just as they tiptoed up behind him. Freeman Hunt, with a grin on his face, rushed straight at the Boy Scout. But Tubby was prepared this time, at any rate. He dashed the torch, end down, on the floor of the hold, extinguishing it instantly. At almost the same instant, he rushed straight at the place where he had last seen Freeman Hunt.
