We immediately put out No. 8 panels which mean that “the battery has fired.” Shrapnel is used during these trial shots as the observer in the airplane can easily see by the bursts just how far or close they come to the target and this is what he does. After having seen where the shots landed the observer flies back over our station and signals down to us the number of yards to the right or left of the target and _short_ or _over_ the shots landed. The telephone man sends this to his Battery Commander, who computes the necessary correction in aiming the gun, and the performance of signaling and firing is repeated until every shot becomes a _target_, that is, hits squarely on the mark. At intervals of half-an-hour the balloon station, that is, the captive balloon, sends out _meteorological data_, which means weather reports, chief of which are the barometer readings, by wireless and this we get and transmit to the B. C. station by telephone, At 4 P.M. the batteries cease firing, we take down and pack up our station and go back to camp. As I have said we repeated this performance for a month until we were letter perfect in cooperating with the airplanes. And then one morning almost without a word of warning we were told to pack up our personal equipment. We turned over the wireless apparatus to the supply officer of the company and by evening we were on our way to Camp Mead, Maryland, which was one of the ports of embarkation for overseas men. We spent ten glorious days at Camp Mead without a tap of work to do. On the morning of the eleventh day we boarded a big three stack troop-ship, weighed anchor and by noon we were off for France. To most of the men aboard, many of whom had never seen the ocean before, and some of them were never to see it after, the voyage was a great joy or a big sorrow according to the states of their stomachs, but to me it was a long and tiresome trip. The ship had been altered from a floating palace into a purveyance which would carry the greatest number of men it was possible to crowd into her. On the morning of the eighth day after we had embarked we landed at Liverpool and were given a royal reception by the enthusiastic Britons. The way they warmed up to us was a revelation to me for I had no more idea that an Englishman could change his attitude toward an American than that a jaguar could change his spots. The miracle had come to pass nevertheless. From Liverpool we went on to London riding in first class compartment coaches as if we owned the railroad. We were in Lunnon, old dear, for a week in which time we paraded, and were dined and petted as if each man-jack of the whole bloomin’ outfit was a Beau Brummel, a Count D’Orsay, a Lord Byron, or some other dandy of a century before. I forgot entirely that a world-war was going on across the Channel and that we were over there to fight monsters of the kind that bayoneted babies, instead of living like dukes.
