"Where are you going, Captain?"

"To my cabin, sir, to take a nap."

"Nap?" echoed the owner, in great amazement.

"Yes, sir; I am afraid I shall be up about all night. Just now there's a chance for me to store up some sleep."

"But the chase?"

"Mr. Davis will have his orders to call me if we appear to be losing ground at all."

Mr. Baldwin looked his astonishment. He did not yet know the Motor Boat Club boys as well as he might have done. Dick Davis was up on the bridge, keen-eyed and alert. Dick knew well enough what to do, and he could call the young captain at need. Besides, Joe Dawson was up there with the second officer, watching the relative speeds of the two boats.

When Tom Halstead turned out again he had put two hours of sleep into his supply of reserve force.

"How do we stand, now, Mr. Davis?" asked the young skipper, reaching for the speaking tube.
