y, when
the report reached him. "That's two in two days."

"No news of Leroy yet?" asked Tom and Jack, as they went out of
headquarters after reporting.

"None, I am sorry to say. It is barely possible that he landed in
some lonely spot and is still hiding out--if he is not killed. But I
understand you two young men had something to request of me. I can give
you some attention now," went on the commander of their squadron.

"We want to be transferred!" exclaimed Tom. "Now, that Pershing's men
are here--"

"I understand," was the answer. "You want to fight with your countrymen.
Well, I would do the same. I will see if I can get you transferred,
though I shall much regret losing you."

He was as good as his word, and a week later, following some strenuous
fights in the air, Tom and Jack received notice that they could report
to the first United States air squadron, which was then being formed on
that part of the front where the first of Pershing's men were brigaded
with, the French and British armies.

Du Boise, who had brought word back of the fate that had befallen Harry

to depend on you to give us some information regarding Leroy. If the

to bother to send us word. But I'll let you know as soon as I hear
anything."

"Is his sister here yet?" asked Jack, for Tom and he had been too busy
the last two days, getting ready to shift their quarters, to call on
Nellie Leroy.

"She has gone back to Paris," answered Du Boise. "There was no place for
her here. I can give you her address. I promised to let her know in case
I got word about her brother."

"I wish you would give me the address!" exclaimed Tom eagerly, and his

CHAPTER V. THE RESOLVE

"Well, to-morrow, if all goes well, we'll be with Pershing's boys,"
remarked Jack, as he and Tom were sitting in their quarters after
breakfast, the last day but one they were to spend in t
