Jack jumped to his key. If the ship was sinking, he would show them that he could live up to best wireless traditions.

Out into the black, fog-bound night went thundering and volleying the stricken ship’s appeal for aid. But the boy did not send out the S.O.S.; that could only be done by the captain’s orders. His intent was to inform any ship within his zone of their plight, so that they might stand by to render assistance if it should be necessary.

But no answer came to the wireless appeal that the boy flung broadcast through space. Time and again he tried to summon help, but none answered his call.

The captain himself came aft, leaving things forward to the first officer. The second officer and the carpenters were sounding the ship to discover if her wound were mortal or if she could make port somehow.

Somewhere off in the fog Jack could hear the swells breaking as if on a rocky coast. He knew they were beating against the iceberg that the ship had crashed against!

Jack looked up as the captain entered the wireless room. Never had he admired the man as he did in that instant. Pale, but stern and resolute, Captain Braceworth looked the man of the minute, a fit person to cope with the dire emergency that had befallen them.

“Any ships in our zone, Ready?” he asked calmly.

“No, sir, I’ve been trying to raise some and——”

“Very well. Keep on. If you get into communication, report to me at once.”

“Yes, sir. Are—are we badly hurt, sir?”
