He lay down and closed his eyes; and in spite of the seriousness of his situation, and the hard floor upon which he lay, he was soon asleep.

Meanwhile, Hal and Uncle John made all haste toward the headquarters of the Italian general staff, which at the moment were in Venice. It took Hal some moments to convince several subordinate officers that it was essential he see the commander himself, but after some explanations the lad, accompanied by Uncle John, was ushered into the presence of the general.

Hal laid bare the details of the plot in a few words, and the Italian commander eyed him incredulously.

"How am I to know you are telling the truth?" he demanded.

"For one reason, because I don't lie," replied Hal. "Besides, if you doubt me, sir, it would be well to be on the safe side, anyhow. It can do no harm to take the necessary precautions."

"What you say is true," replied the general.

"A wire to General Ferrari might tell you we are to be relied upon," continued Hal. "We were so fortunate as to be of some slight service to him recently."

The Italian commander glanced at his watch.

"It is best to be on the safe side," he said. "I shall take the necessary precautions, meanwhile wiring to General Ferrari, as you suggest. In the meantime, I fear I shall have to detain you, at least, until I receive a reply to my wire."

"But, sir," Hal protested, "I would like to go back and find my friend."
