"Oh!" he cried, "if only I could be with Captain Hardy when he sees the
Chief of the Radio Service, I'd _make_ the Chief understand that we can
help. We could be just as useful to the radio men as the Baker Street
Irregulars were to Sherlock Holmes. Oh! I just wish I could be with
him. I wonder when he will see the Chief."

Henry picked up the envelope and examined the postmark. "This was
mailed yesterday morning," he muttered, "and Captain Hardy said he was
going to Washington to-morrow. That's to-day. Maybe he's with him
this afternoon. Maybe he went this morning. I'm sure he knows by this
time what the result is. Oh! I wish I were with him. I'd just _make_
that Radio Chief take us."

As he spoke a telegraph messenger entered the yard. He caught sight of
Henry in the workshop door. "Hey!" he called. "Does Henry Harper live
here? Got a message for him."

Henry was almost too much amazed to answer. He had never received a
telegram in his life before.

"Hey!" called the messenger again. "Are you asleep?"

"No," was the answer, "and I'm Henry Harper."

"Then why didn't you say so?"

Henry ran forward and seized the yellow envelope. "Where's it from?"
he asked.

"Washington," said the messenger.

"Washington!" repeated Henry. "Washington! Then we're to go."

"If you'll sign here," said the messenger, "I'll go. I can't stand
here all day. Nothin' to pay."

Henry signed the messenger's book, then tore open the envelope and took
out the following telegram: "Want you, Roy, Lew, and Willie to meet me
Pennsylvania Station New York City Friday two P. M. for work suggested
in your letter."

CHAPTER II

HENRY OVERCOMES AN OBSTACLE

Could the messenger boy have seen Henry after the latter had read the
telegram, he would soon have changed his mind as to Henry's sleepiness.
For a very brief space--just long enough to reread the message once or
twice--Henry stood like one dazed, as motionless as a statue, and as
silent as a sign-post. Then he gave a loud whoop and began to dance
around the little shop. For a boy who was ordinarily so sober as
Henry, such conduct was scandalously riotous. He skipped about the
tiny wireless room, waving his hat in his hand, cheering for the Camp
Brady Wireless Patrol, and making loud declarations as to what that
organization would do to the enemies of the country.

Ordinarily Henry would have restrained himself. Not even the news that
the Camp Br
