"A collision," he told himself. "A bad one too—full tilt into one another. It's shaken the electric light out. Lucky they keep an emergency oil lamp going."

The temptation to dash up on deck was strong within him, and had he been alone on the vessel, with none to care for, no doubt he would have obeyed the inclination. But there was Sadie; Jim was her protector. He dashed at once towards her cabin, and came upon her at the doorway, looking frightened.

"There's been a collision, Sadie, dear," he said, endeavouring to keep his voice quiet. "Guess we may have to move; let me come in and fix you."

The child was not undressed, fortunately, and Jim at once pushed into the cabin, groped for one of the cork life preservers which are placed in overhead racks, and adjusted it to her body.

"Now," he said, "bring a warm coat, and leave the other things. Ah, here's Tom!"

"Sah; me here, right enough. You's not hurt, nor missie?"

"Not a scratch, Tom. Just take Sadie right up on deck and stand beside her. That Sam?"

In the dusk outside there was a second figure, and behind that another. The faithful negroes, and Ching Hu, the Chinaman, had rallied at once to their youthful master.

"Me, in course," cried the little Sam. "Guess this here's a collision. But we ain't got no cause to mind; not at all, not at all, missie."

"Get life belts, put them on, and then go on deck," said Jim shortly. "Sadie, take charge of this bag of dollars. I'm going up to see what's happened."
