Telephone and telegraph wires also are a certain menace to aviators. They form a regular network behind the lines, while on every aviation-field there are in addition wireless aerials to avoid. Many a returning pilot has forgotten them in his haste to get back to camp, and fouled them, to his regret. One pilot I knew met his fate in this way. He had been wounded by a shrapnel-ball over the German lines, and had managed to return to his own field. He was so weak from the loss of blood that in his anxiety to land quickly he forgot the aerials. His machine caught the wires and fell to the ground. Both the pilot's legs were broken in the fall and he died, not so much from his wound as from this unfortunate accident.

Still another risk is encountered when flying in the clouds. 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.

Shells also have to be carefully avoided, for, though destined for some far-away target below you, they sometimes in their flight destroy aeroplanes unintentionally. As I have already explained, we devoted much time to this subject at Châteauroux, learning the trajectories of the different calibers. Still, at the front, the theory is not so easily put into practice. 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; merely the dulled sound caused by the sudden displacement of the air.

My own machine finally arrived, after delays that seemed interminable, and my two mechanics immediately set to work installing the various instruments, and painting it. These two men were personally responsible to me for the condition of the motor and planes, but, as pilot, I was the master of the machine, which was reserved for my own use. In fact, each aeroplane has painted on its body and rudder the name and distinguishing marks of its pilot and escadrille.

After a few short flights I became aware of the fact that my biplane, in spite of all my efforts to correct it, showed a strong tendency to lean to the right. At times I could hardly make a turn to the left. This was a serious matter at the front, as an enemy might at any moment appear on my "weak" side and I would be placed in a serious position. I therefore mentioned the matter to my captain. To my surprise, he immediately ordered a new machine for me and gave directions that the one I was using should be sent back to the factory. The defect in this particular case was one mechanics could not remedy, and it seems that it was nothing out of the ordinary to send a machine back to the shops. At the front a pilot must have a perfect machine to work with or none at all. The life of a good aeroplane seldom is more than fifty hours of actual flying.

During this time the organization of the escadrille was perfected. The pilots were divided into two "watches," one-half being on duty while the other was "standing by" ready for service in case of emergency. All the pilots except myself were "disponibles." I was exempt because I had no machine, and was therefore for the time being my own master, even when it came to rising in the morning. When the others on duty were awakened, at early dawn, I would be awakened with the rest. My turn had not yet come, however, and I could just turn over and sleep to my heart's content.

Our camp looked like a little tented city; there were seven enormous canvas hangars, and grouped about these six other tents, each serving a particular purpose: captain's office, wireless plant, telephone central, repair-shop, photographic division, and kitchen. At one end of the field were the living-quarters of the captain and the observers, while at the other were parked the thirty automobiles of our two escadrilles. On the opposite sides of the field were the quarters of the pilots of the two escadrilles. The mechanics slept in the hangars with their machines.

Considering everything, we were fairly comfortable. The pilots of each escadrille shared two large tents, and in addition each group had a large mess-tent. Inside each sleeping-tent each one of us had a little alcove. Our cots were raised on wooden platforms. At one end we fitted up a shower-bath, for which purpose a gasolene tank punctured with holes proved ideal. Of course, every time you wanted a bath some one had to empty pails of water into the "tank" above you. Our mess—"popotte" they call it in the French army—was very good. We had a regular daily allowance from the government, but this was not always enough to buy all the supplies we needed. We therefore instituted a system of fines, and our treasurer provided our table with a small tin box in lieu of a centrepiece.

Bad language or talking "shop" before coffee involved a ten-centime fine, which had to be dropped into the bank at once. This regulation proved a godsend to the mess—and to our conversation.

As I was not "disponible," I was sent on several trips with the staff automobile. Its most frequent runs were to the artillery headquarters to deliver photographs of the enemy's positions. These were situated in a near-by village, within sight of the German trenches. All the roads approaching this place were masked, and the town itself was in ruins. Everywhere sand-bags reinforced the stone walls. The telephone central was a veritable fortress, and continually within the zone of the German artillery "strafes." The life of the officers of the Etat-Major was certainly not an enviable or an easy one.
