A head appeared in the opening of the hatchway, while a second later a cloud of smoke shot upward, hiding the head and setting the owner coughing. But the derrick above swung over promptly, and the rope descended.

"You two men get to one side and rest," said the officer. "I and this friend here will see to the man. Now," he went on swiftly, "lend a hand while I pass the rope round this poor chap. That's the way. Now steady him while I go aloft. You'll get your men down as you want 'em."

He had already spoken to an officer on duty down below, and now went clambering upward. A moment later Joe was guiding the unconscious body of the sailor as he was hoisted upward. Then, cramming the towel close round his nose and mouth, he dived into the clouds of smoke till, aided by the electric light, he saw an officer.

"Shall I bring some of the men down now, sir?" he asked. "I've two dozen up above, all ready to lend a hand. I thought it would be best to employ them in two batches."

The officer, a young man of some twenty-five years of age, rose from the box he was helping to lift, coughed violently, and then accompanied Joe back to the part directly under the hatchway.

"My word," he gasped, when at length a violent attack of coughing had subsided and allowed him to speak, "we'll be glad to have you. That's hot work in there. You've two dozen, you say? Then bring along half of them; they'll be mighty useful."

Joe went swarming upward at once and, arriving on the deck, promptly told off twelve of the men. He was down again with them within a few seconds, at once leading them forward to where the work was in progress.

"That you?" asked the officer, peering at him through the smoke and coughing. "Then get to at these boxes. We're pulling them aside, and till we've got a heap more away we shan't be able to reach the spot where there's fire. When we do, things won't be so easy. There'll be a burst of smoke and flames, I should imagine."

"Then we'd better have the other half of this gang ready with sacks and blankets damped with water," cried Joe. "A hose wouldn't stop the fire, and the water would do a heap of damage. Eh?"

"You're the boy!" gasped the officer. "That's an idea; will you see to it?"
