"Who will run the launch?" he inquired.
"I'll give you the captain and one of the men," said the boy. "Carg's an old traveler and knows more than he appears to. Besides, he speaks German. We can't spare very many, you understand, and the ambulances will keep Maurie and me pretty busy. Patsy will be missed, too, from the hospital ward, so you must hurry back."
"Two days ought to accomplish our object," said Uncle John.
"Easily," agreed Gys. "I've arranged for a couple of girls from the town to come and help us to-day, for I must save the strength of my expert nurses as much as possible, and I'll keep them with us until you return. The French girls are not experienced in nursing, but I'll take Miss Patsy's watch myself, so we shall get along all right."
Mr. Merrick and Jones returned to the deck.
"Well?" demanded Patsy.
"Get ready," said Uncle John; "we leave in an hour."
"For Charleroi?"
"Of course; unless you've changed your mind."
