“Better give it another turn, hadn't I, to make sure? If two turns fixes it so we don't hear for a couple of hours, another one ought to shut it up for a week. That's arithmetic, ain't it?”

The laugh that followed this was cut short by Hazeltine's throwing the door wide open.

Captain Eri, close at the electrician's heels, saw a long room, empty save for a few chairs and a table in the center. Upon this table stood the testing instruments, exactly like those in the receiving room downstairs. Three men lounged in the chairs, and standing beside the table, with his fingers upon the regulating screw at the centerpiece of the recorder, was another, a big fellow, with a round, smooth-shaven face.

The men in the chairs sprang to their feet as Hazeltine came in. The face of the individual by the table turned white and his fingers fell from the regulating screw, as though the latter were red hot. The Captain recognized the men; they were day operators whom he had met in the village many times. Incidentally, they were avowed friends of the former electrician, Parker. The name of the taller one was McLoughlin.

No one spoke. Ralph strode quickly to the table, pushed McLoughlin to one side and stooped over the instruments. When he straightened up, Captain Eri noticed that his face also was white, but evidently not from fear. He turned sharply and looked at the four operators, who were doing their best to appear at ease and not succeeding. The electrician looked them over, one by one. Then he gave a short laugh.

“You damned sneaks!” he said, and turned again to the testing apparatus.

He began slowly to turn the regulating screw on the recorder. He had given it but a few revolutions when the point of the little glass siphon, that had been tracing a straight black line on the sliding tape, moved up and down in curving zigzags. Hazeltine turned to the operator.

“Palmer,” he said curtly, “answer that call.”

The man addressed seated himself at the table, turned a switch, and clicked off a message. After a moment the line on the moving tape zigzagged again. Ralph glanced at the zigzags and bit his lip.

“Apologize to them,” he said to Palmer. “Tell them we regret exceedingly that the ship should have been kept waiting. Tell them our recorder was out of adjustment.”
