world with the powerful glasses. Paris was now far below, a blur of
white and gray. Above, the heavens were of the silkiest blue, beautiful
in their infinite depths, with tiny clouds floating here and there like
whitecaps on an ocean.
"What do you see now, John?"
"Nothing but one of the most beautiful days that ever was. It's a fine
sun, that you've got over here, Philip. I can see through these glasses
that it's made out of pure reddish gold."
"Never mind about that sun, John. America is a full partner in its
ownership and you're used to it. I've heard that you have more sunshine
than we do. Watch for our companions of the air, friend or foe."
"I see them flying; over Paris, but none is going in our direction. How
far is our port of entry, Lannes?"
"We should be there in two hours, if nothing happens. Do we still have
the course to ourselves or is anything coming our way now?"
"No company at all, unless you'd call a machine about three miles off
and much lower down, a comrade."
"What does it look like?"
"A French aeroplane, much resembling the _Arrow_."
"Is it following us?"
"Not exactly. Yes, it is coming our way now, although it keeps much

Lannes was silent for a little while, his eyes fixed on his pathway
through the blue. Then he said:
"What has become of that machine, John?"
"It has risen a little, but it's on our private course, that is, if we
can claim the right of way all down to the ground."
Lannes glanced backward and downward, as well as his position would
allow.
"A French plane, yes," he said thoughtfully. "There can be no doubt of
it, but why should it follow us in this manner? You do think it's
following us, don't you, John?"
"It begins to look like it, Phil. It's rising a little now, and is
directly in our wake."
"Take a long look through those glasses of yours."
John obeyed, and the following aeroplane at once increased in size
tenfold and came much nearer.
"It's French. There cannot be any doubt of it," he said, "and only one
man is in it. As he's hidden by his flying-suit I can't tell anything
about him."
"Watch him closely, John, and keep your hand on the butt of your
automatic. I don't like that fellow's actions. Still, he may be a
Frenchman on an errand like ours. We've no right to think we're the only
people carrying important messages today."
"He's gaining pretty fast. Although he keeps below us, it look
