“ We were at Bar-le-Duc, the terminus for Verdun. What an air of mystery there was about the station at "Bar." We could hear the distant roar of the cannon defending the banks of the Meuse. Everywhere men moved about with a sort of suppressed excitement. "Camions" rumbled by in hundreds. In the freight-yard troops filled every available space not already taken up by the newly arrived artillery. Nearly all my travelling companions left me here. For a moment I wished that I too had been ordered to the Verdun sector. It was after sundown when the train drew into the station at Toul. ”

“ My experience in the French Aviation Service early taught me what a difficult and scientific task it is to pilot an aeroplane. By piloting I mean flying understandingly, skilfully; not merely riding in a machine after a few weeks' training in the hope that a safe landing may be made. In America many aviators holding pilot's licenses are in reality only conductors. ”

“ Another danger, which I would never have thought of if an experienced pilot had not pointed it out, lies in the cables mooring the captive balloons. These are invisible to an approaching aviator and to collide with one means a fatal smash. When flying low enough to pass under the "saucisses," aviators must watch out for these "tethers." Nevertheless, you can always take advantage of one of their peculiarities. The cable always stretches to windward, and in a good breeze it stretches far. By keeping well to leeward you can always rest reasonably assured that you are on the safe side. ”

“ Four are mounted on each side of an aeroplane. At the head of each rocket is a large dart, resembling a salmon-gaff. The tails of the rockets are wound into spiral springs, which are held in sockets. All eight rockets are fired at once. They are ignited as they leave their sockets, and travel with lightning speed.
Swinging lazily above the field was a captive balloon. At one end of Le Bourget was a line of waiting aeroplanes. "This is the second. They have already brought down one balloon," remarked the man at my elbow. The hum of a motor caused me to look up. ”

“ For some reason my own machine was delayed "en route," and did not arrive for a week. This was time I could ill afford to lose, so the "chef pilote" took me as a passenger in his biplane to familiarize me with the ground in our sector.
We started late one afternoon. The atmosphere was extraordinarily clear. Every detail in the landscape stood out boldly, and as we rose the dozens of camps in the immediate vicinity spread out below us like models set in a painted scenery. The valleys, the tents, the guns, the troops, all were visible to the naked eye. ”

“ First we were taught how to read a map, how to judge the height of hills and the size of towns, so that when flying we would know at a glance just where we were. This, we later appreciated, is a very important matter. When passing through clouds or mist an aviator may become momentarily lost, and the instant he again sees the ground he must locate on his map the country he views or else land and ask where he is. Aerial navigation may not be as complicated as that employed by mariners upon the high seas, but it is not easily mastered by any means. ”

“ It was nearly two months before I was allowed to make my first flight. The French idea is that before a pupil commences his apprenticeship as a pilot he must understand thoroughly the machine he is going to handle and know just what he is trying to do in the air. Together with twenty-five other men, who began their studies at about the same time, I was ordered to attend the theoretical courses. When not in the classroom we were stationed on the aviation-field where we could watch the more advanced "élèves" fly, thus familiarizing ourselves by observation with all the details of our profession. ”

“ The French seem to have the same theory about aviation. No one who has not tried it can appreciate the tremendous strain of flying. After a few hours in the air I find that I am more exhausted than I used to be after a hard football match.
While the matter of personal habits is left to the aviator's judgment, he is usually cautioned about drinking, smoking, and even overeating. You need all the strength there is in you when in the air. The French, as every one knows, drink wine as we drink tea and coffee. ”

“ Unlike the conscript "poilu" of the army, every aviator is a volunteer. Aviation is far more dangerous than fighting in the trenches, yet there are many who have preferred the extra risk of being in the Aviation Corps to the tedium of remaining in the narrow-walled trenches. I believe there is at present a waiting list of over six thousand men who have applied for service in the Flying Corps, but for whom there are still no vacancies. A pilot may resign his commission at any time and return to his regiment at the front, but the majority of the "vacancies" are caused by casualties. ”

“ At the front a pilot always has two "mecaniciens" to take care of his machine, but if on account of a breakdown he should have to land in hostile territory he must be able to make the necessary repairs himself, and make them quickly, or else run the risk of being taken prisoner. When flying, the pilot can usually tell by the sound of his motor whether it is running perfectly or not. Many a life has been saved in this way—the pilot knowing in time what was out of order before being forced to land in a forest, on a mountain peak, or in some other equally impossible place. ”

“ A cloud is dangerous at any time because there may be an enemy—or, in fact, any machine—in it. If you enter the mist you may be going head on into another aeroplane without having the slightest warning of its presence. Your own motor makes so much noise that you never under any circumstances hear that of another machine until too late. You are in consequence deprived of both your eyesight and your hearing. At the front the risk of meeting an enemy aeroplane under such circumstances can never be overlooked, for often fighting machines use the mist to cover their presence. ”

“ Occurring near the ground a loss of speed is certain to result in a smash-up. If high in the air a "vrille," or tail spin, is generally the result. By this is meant coming down in a whirlpool, spinning like a match in the waste of a basin. The machine takes as a pivot the corner of one wing and revolves about it. The first turn is very slow, but the speed increases with each revolution. The only hope of escape is to dive into the centre of the whirlpool. Even then, if the motor is turned on, the planes will fold up like a book. ”

“ Even in France, where the Aviation Service is constantly working under the forced draught of war conditions, no less than from four to six months are devoted to the training of finished pilots.
Although I have just come from France, the progress of aviation is so rapid that much of my own knowledge may be out of date before I again return to the front. But interest in flying is becoming so general among Americans that the way the aviators of France are trained, and what they are accomplishing, should attract more than passing attention. ”

“ The modern aeroplane is so stable that when it is made to dive it always attempts to rise and resume its flight. In the "vrille," on the other hand, this resistance is overcome, and the machine spins down with incredible rapidity. The beginner usually commences by making one turn. He allows his machine to lose its speed and slip off on the wing. After engaging in a spiral, instead of continuing he then resumes his flight. The second time two turns have to be made. More and more are made until the pilot feels that he has mastered the trick to his satisfaction. ”

“ Faulty landings are also very common causes of accidents. It takes a beginner a long time to train his eye to make a perfect landing, and even experienced men now and then smash up on the "atterrissage." A few inches sometimes make a great difference. If the pilot does not check his speed in time he will crash into the ground and "capote," that is, turn over. If he pulls up too soon he will slip off on the wing or land so hard that the machine collapses. Not only the manner of landing but gaining the exact place of landing is difficult. ”

“ What surprised me most was to learn that night flying is really easier than day work. The reason given is that after sunset there are no "remoux," and that, when it comes to making landings, the aviation-fields are so well lighted that the pilots have no more difficulty making contact than in the daytime. It is another matter, of course, if an aviator meets with a mishap and is forced to alight elsewhere. ”

“ It seems almost impossible to keep track of all the artillery massed by your own side, especially in such a sector as Verdun, where the guns often were placed so close together that their wheels almost touched. On more than one occasion when flying quietly through the air my machine has given a sudden lurch, and I have heard the dull "tung" of a passing shell. There is none of the whistling we are accustomed to on the earth ”

“ In this branch of aviation the weight of the pilot does not matter so very much, whereas in the case of the little Nieuports, if the aviator exceeds the prescribed weight, he has to choose between not piloting the machine or starting on his flight with a supply of gasolene reduced by the amount of his excess weight.
Finally, there are the heavy-armored bombardment machines, with a carrying capacity of over one thousand pounds. They are the slowest machines of all, and their work is both tiring and tiresome, as their flights are made mostly by night. ”

“ The following morning was the day fixed for my ten-thousand-foot ascension. The atmosphere was remarkably clear, and I felt an extraordinary sense of freedom and power as I rose from the ground. The earth below me was bright with color. ”

“ The élève must follow every move of his pilot, until he appears perfectly at home in the machine, and then he is allowed to hold the controls alone. Each flight lasts only about five minutes, the French theory being that an aviator must take his instruction in small doses. In the interim, as in the preliminary courses, he remains on the field, observing and studying the mistakes of his comrades. If the progress of the instruction is too rapid, the pupil has not the time to grasp each step that has been passed and cannot, therefore, become an expert pilot. ”

“ A bad landing. My first trip was to the aviation school near Bourges, situated on the estates of the Count d'Avord, who has lent the ground to the government for the duration of the war. It is a much larger school than any I had attended, and its instruction covers every type of machine. The most important course given is that in night flying. All the aviators who have been selected for the bombarding-machines and for the work of guarding cities are sent here. Their life is the exact opposite of that led by the average pilot, for they sleep all day and work all night. ”

“ My first assignment was to a Penguin, so called because it is nothing more than a Blériot monoplane with its wings cut down so that it cannot fly. The Penguins, however, are just as difficult to manage as a full-fledged flying-machine, for on the ground your movements have to be more rough than when flying in the air. There are so many irregularities and air currents to affect your course that you have to be very quick with the controls. The Penguin, besides, does not answer the rudder as easily as the other types. ”

“ While in line of flight, the force of the motor will maintain the speed, but when the motor is shut off and the pilot commences to volplane the force of gravity produces the same result. There are two ways of knowing when you are approaching the danger-point—by closely watching the speed-indicator and by feeling your controls. The moment the controls become lifeless and have no resistance you must act instinctively and regain your momentum, or it is all up with you. While climbing you may lose speed by forcing the motor and climbing too rapidly. ”
