Cardon drew in his breath.

He saw at once their object. Instead of going down to kill the man they imagined to be below, they were bottling him up. No man, however strong, could force his way on deck through that hatch once closed.

Again he felt Floyd's toe, as if it were inquiring if all was right, and, again reaching back, he signaled an answer. His eyes were glued to the malefactors, who were now at the main hatch removing the tarpaulin.

It did not take long. Then they worked the locking bars loose and removed the hatch with scarcely a sound. He saw Schumer produce something. It was a lantern. They lit it, and Schumer, with it in his hand, vanished down the main hatch into the hold. He was there a full minute that seemed a full hour to the man at the scuttle; then he reappeared. The hatch was closed, but the tarpaulin was not replaced, and, leaving it, they came forward, Schumer carrying the light and Luckman following him. They passed the caboose, and were lost to sight.

"Now is our time," whispered Cardon, turning from the scuttle. "We've got them forward in a close space. Cock your gun and follow me."

He opened the caboose door and found a vacant deck.

For a moment he thought that the two men had gone overboard; then he saw the truth. They had gone down into the fo'c'sle. Floyd saw the situation and the chance in the same flash with Cardon, and in a moment they had flung themselves on the fo'c'sle hatch cover and driven it to.

The men who fancied they had bottled Floyd were bottled in their turn.

They had imagined a vain thing, and the fact was evidently borne in on them now to judge from the sounds coming from below.

The cover of the fo'c'sle hatch was placed at such an angle with the fo'c'sle companionway that it was impossible to make much noise by striking upward from below, and its thickness was well demonstrated by the feebleness of the noise of the men who were now shouting at the top of their voices.
