"Then you're just the man the general wants to see," replied Wilson. "He sent a message to the colonel asking for the services of a man who was cool and plucky, and who could also ride a motorcycle. I don't know of any one else who can fill the bill better than you."

"I'll be glad to do whatever's wanted of me," replied Frank, and with a word of farewell to his comrades he accompanied the corporal to headquarters.

Here he was ushered into the presence of a group of officers who were poring over a large map spread out upon a table.

"Is this the young man you were telling me about, Colonel?" asked the general, a tall, powerfully built man, looking sharply at Frank from beneath a pair of bushy eyebrows.

"Yes, General," replied the colonel. "Captain Baker vouches for his coolness and courage and his quick thinking in an emergency. And I'm told he understands all about motorcycles."

"Just the man," commented the general. "I want you," he continued, addressing Frank, "to carry a message for me to the British commander on our right. Our division has lost touch with him and the field telephone is not working. Probably it has been cut by the enemy. The message is most important and I want you to make all the speed you can. Go and get ready now and report to your captain, who will hand you the papers. He will have a machine ready for you. That is all."

Frank hurried back and made his preparations, which were brief. While he worked he told his eager companions of the errand with which he had been entrusted.

"Wish I were going with you," remarked Bart.

"Same here," said Billy.

"That would be dandy," agreed Frank.
