The count arrived quickly. He led off by abusing Leutter in front of several of the crew for having disturbed him; then, on being told of what had occurred, he changed completely round and complimented his subordinate on his sagacity.

"Z64's done, Herr kapitan," declared Hans Leutter. "She's sinking rapidly. Half an hour, perhaps, will find her falling into the sea. We must take steps to safeguard ourselves."

"Quite true," agreed the count. "Although there will be enough buoyancy in the envelope to keep it afloat for hours--days even. What do you propose to do?"

"Throw overboard everything of a weighty nature, Herr kapitan," replied the Unter-Leutnant. "We can empty the petrol tanks, since we have no further use for the motors. Meanwhile we must send out a general wireless call for assistance to all ships within a hundred or two hundred kilometres of us."

Count Karl von Sinzig thought this quite an excellent idea. At least, he said so. At the back of his mind he had a hazy notion that even now there was a chance of winning the Chauvasse Prize. There was nothing in the conditions forbidding a competitor----

His ruminations were interrupted by the appearance of the wireless operator, who reported that both the transmitter and the receiver were out of action, and that the wireless cabin bore signs of having been struck by lightning.

"Can't you effect repairs?" demanded von Sinzig.

"I am sorry I cannot, Herr kapitan," replied the operator.

"A useful wireless man you are!" commented the count, caustically.

The man saluted and backed away from his chief, congratulating himself that he had come off so lightly. But von Sinzig was rather pleased than otherwise that the wireless was out of action. It furnished him with a good excuse to put a certain little plan into execution.
