"Hum," said Dawson, between whom and his Chief was a very close friendship. "I suppose I must toddle round and see what the little man wants this time. Last month he had secret wireless installations on the brain."

Dawson found the First Lord striding up and down his big room. All round the walls were set great maps bristling with pins to which were attached numbered labels. Each pin represented a ship, and each ship was obedient to an order flashed from the big aerials overhead. Here was the Holy of Holies, the nerve ganglion of the English Navy, and here, striding up and down, the man who could jab the nerve-centre with his finger whenever he pleased. He often pleased. Then he would gloat over the pins as they skipped about the maps.

Chief Inspector Dawson was announced, and stood to attention.

"Ha!" cried the First Lord, "so you are Dawson, the Master of Spies. We need you, Dawson; the country needs you; I need you. You have a great chance this day to show your quality, Dawson. Those of whom I approve, I advance. They become great men. Am I to approve of you?"

Dawson observed that he could not well say until he learned what was wanted of him.

"Ha!" cried the First Lord again, "you are a man of few words. I like those with me who do not talk. When there is talking to be done—well, I can do a little in that line myself. Among my instruments I demand silence."

Dawson said nothing. The First Lord struck a bell; a servant in blue uniform appeared. "Will you please tell his lordship that Chief Inspector Dawson is here, and that I await his presence."

The man retired and presently returned. "His lordship is in his room making out the orders for the Fleet. He bids me say that he is quite at your service."

The First Lord flushed, and glanced hurriedly at Dawson, who stood at attention, stolid, silent, immovable. It would seem that he read nothing in the message.

"The Mountain is old and stiff in his joints," remarked the First Lord playfully. "When he settles into his chair, it would take a bomb to lift him out. We are young and active; we must consider the infirmities of age. Mahomet will go to the Mountain, and you will please to follow."
