After four months of drill and riding, pistol and rifle practise on the target range, in fact just as we were beginning to consider ourselves old cavalrymen, we were given a sudden jolt by being told that no more cavalry would be sent overseas and that we would be changed to light field artillery. Now there are a couple of lines in an old army song that run like this: “The Infantry for bravery, The Artillery for slavery.” We were a badly disappointed crew, but a good soldier is one who obeys orders no matter how tough they are and we were good soldiers. In due course of time we were shipped to West Point, Kentucky, where we were to receive our artillery training in seventy-two days and then go overseas. Because I had been a wireless, or _radio_, operator as it is now more often called, and because wireless is an important part of artillery I was immediately picked to go to the radio-school. I laughed at the idea of my going to radio-school. What’s the use when I am already an expert operator and had been in the Navy? But I found out there were still a few things I could learn about wireless. In the artillery the _eyes_ of the army, which is the aviation section, provides the artillery with airplane and balloon service and in order to cooperate successfully with them the wireless operator must have a special training. For three weeks or so we did nothing but _buzzer_ practise; that is a buzzer, which is an electric bell without the bell, is connected in circuit with a battery, a telegraph key and some twenty head-phones. The beginners put on the receivers and an instructor worked the key. As I could easily take twenty words a minute I was made an instructor. Then there were lectures on the elements of electricity and magnetism and by the end of the first month the class was ready for the fundamentals of wireless telegraphy. All of that was old stuff for me and as they say in the army it was _pickin’s_. The time came when we were introduced to the real wireless apparatus and although the sets were portable and of shorter range than any I had handled since I was a kid operator they were certainly beauties. There were three different types or wireless sets; each one was designed to cover a certain distance, and each sending set had its special receiving set. The range of the smallest set was about a mile, while that of the largest was about twenty-five miles. These are very short ranges but enough for army purposes where messages are sent from the trenches through one operator after another or relayed until they reach headquarters. As I said before the purpose of the wireless stations is to cooperate with airplanes and balloons and aid in the control of artillery fire. So in the months that followed our work was to go out on the firing range with the batteries and to cooperate with the airplanes and balloons.
