"I am sorry about it, for I know how keenly you feel and how eager you are to help your country. The best way you can do that is to continue in school, learning all you can and making yourselves more and more efficient as wireless operators. In a very short time, I suspect, Uncle Sam will be in pressing need of good radio men. Then, although you are still young, your chance will come; for your ability is already known to the Chief of the Radio Service through your capture of the dynamiters last summer.

"As you know, our camp is just outside of Washington. I happen to be going into the city to-morrow. Of course, I shall take occasion to lay your suggestion before the Chief. But do not build any hopes on that statement. I have no idea anything will come of it. But it may help the Chief to bear you in mind later on. I am sorry to dash your hopes, but I cannot do otherwise than to tell you the truth. Of course if anything should come of it, I will let you know promptly. Remember me to all the other boys.

"Sincerely yours,
"JAMES HARDY."

Henry's face became longer and longer as he read. When he had finished the letter there was more than a suspicion of moisture in his eyes.

"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."
