e faithful pilot.

"First I must use the glasses to see how it looks at closer range," Jack
continued. "Then I think we ought to have breakfast. This cold air makes
a fellow as hungry as a wolf. I think I must have lost myself for a bit."

Tom did not say anything, only smiled, but he knew that the other had
enjoyed at least a full hour of sleep.

"How far are we from land, Tom, would you say?" next asked the observer,
while he was adjusting the glasses to his eyes.

"Possibly a hundred and fifty miles, perhaps nearer two hundred," Tom
assured him, in a matter-of-fact tone, as though that was only what might
be expected.

"Hello! I can see a vessel already, and heading into the west!" declared
Jack. "Of course I can't make out what she's like, though I bet you her
hull and funnels are camouflaged to beat the band, so as to fool those
Hun submarine pirates with the stripes of black and white. You don't

"Not a chance in a hundred," Beverly assured him. "Besides, those aboard
the steamer are devoting all their efforts to watching for enemies in the
water, and not among the clouds."

They munched their breakfast and enjoyed it immensely. Indeed it seemed
as though they devoured twice as much as upon ordinary occasions.

"Lucky we laid in plenty of grub!" Jack declared, when finally all of
them announced that they were satisfied. "This Atlantic air makes one
keep hungry all the time. Now I can see that steamer plainly, for we've
dropped a little lower. Oh! What can that mean?"

His voice had a ring of sudden alarm about it that instantly aroused
Tom's curiosity. Even Lieutenant Beverly looked over his shoulder as
though he, too, felt a desire to learn more.

"They seem to be firing guns!" continued Jack presently. "Of course we're
far too high to hear the sou
