Ambulance work depends on the supply of gasoline, oil, carbide and spare parts, solid rations and sleep. Success rests in patching tires, scraping carbon and changing springs. Any idea of ambulance work is off the mark that thinks it a succession of San Juan charges. It is hard, unpicturesque work, with an occasional fifteen minutes of tension. "A stretcher makes a serviceable bed, and, warmly wrapped in blankets, one can sleep very comfortably in an ambulance." "A climb of 800 meters in less than 10 kilometers involves mechanical stress." "The unique spring suspension and light body construction make our cars the most comfortable for the wounded of all the types in service." A mechanical detail--but it is in these bits of ingenious mechanical adaptation to human needs that the American contribution has been made. It isn't half enough in a machine-made war to be dashing and picturesque. You must fight destructive machinery with still cleverer engines of relief. The inventive brain must operate as well as the kind heart and the spirit of fearlessness. It is in the combination of courage and mechanical versatility that the best of the American quality has been revealed. Flashes of the soldier life are given by the boys. Canned beef is called by the poilu "singe," or monkey meat. "All that is impossible is explained by a simple 'c'est la guerre.' Why else blindly scrape one's way past a creaking truck of shells, testing 20 horses, two abreast, steaming in their own cloud of sweaty vapor? Why else descend slopes with every brake afire, with three human bodies as cargo, where a broken drive shaft leaves but one instantaneous twist of the wheel for salvation, a thrust straight into the bank, smashing the car but saving its load? 'C'est la guerre.'" "'Chasseurs Alpines': a short, dark-blue jacket, gray trousers, spiral puttees, and the jaunty soft hat 'bérets.' These are the famous 'blue devils.'" "I, who came for four months and have been working eight, can assure any one who is considering joining the American Ambulance that he will go home with a feeling of great satisfaction at having been able to help out a little a nation that appreciates it, and that is bearing the brunt of the fighting on the Western Front." "Among the wounded that our cars carried, was the General of the Division--General Serret"--brought down from the height he had held to be amputated and to die. Another section of twenty-four cars started in at Esternay at the time of the spring freshets, when life was chilly and wet. Eleven received individually the Croix de Guerre. This section served two divisions of the second French Army and had a battle front of from seven to ten miles--the St. Mihiel sector, a region subject to artillery fire. It has been commanded by Oliver Hazard Perry, a descendant of Commodore Perry. They had 1,800 wounded a week, and a mileage of 5,000 kilometers. "Sudbury broke his arm cranking, this morning."
