His word was law in the field hospital, and hence Thad was not at all surprised when he saw him take possession of the best car in sight. The owner, an old though patriotic Frenchman, who had been urgent in trying to do all he could to assist in taking care of the wounded, even to risking his own life in the cause, upon hearing why his car was wanted, instantly handed it over to the good American surgeon, to whom all France would later give praise for his wonderful work during those dark days along the Marne.

“He’s beckoning to us, Thad!” called out Bumpus, who seemed to be intensely interested in the adventure, which appealed to that natural love for excitement such as dwells in the heart of the average boy.

When they hurried over to where the surgeon waited he gave them each his hand.

“Here you are, boys, a pretty decent car placed at your service by this gallant citizen of France. If you live to get through, let us hear from you. As for the car, turn it over to the military authorities to use as they see best. Its owner has already dedicated it to the service of his country and does not expect to ever see it again.”

“Get in, Bumpus, and hurry!” urged Allan, impatient to be off on the run which might mean so much for the French cause.

“Yes, get away quick as you can, boys,” said the surgeon, “before I have a chance to change my mind. Even now my heart misgives me, and I begin to feel doubts as to whether I am doing just the right thing in letting you go.”

Upon hearing him talk in that strain both the others scrambled aboard with all haste. They did not mean to give him a chance to go back on his word if it could possibly be avoided.

“Don’t fear for us, sir,” Thad told him, as he grasped the wheel and took a look so as to familiarize himself with the working of the car, which, of course, differed from any other which he had ever handled, being of French make. “We’re accustomed to getting whatever we go after, and this sort of thing doesn’t feaze us one whit. Good-bye, sir!”

“Good-bye, boys, and the best of luck go with you!”

Then they were off, for Thad had started the motor going while talking, and it required only a simple movement of his hand to complete the operation.
