These exercises proved to be a pretty severe test on his nerves, and at first affected his head and stomach in a truly distressing manner; but constant practice, combined with a determined will, finally enabled him to gain the mastery over them, and he began keenly to enjoy the great and thrilling swoops through space.

At length there came a time to which he had been looking forward most anxiously, and that was the beginning of his training in a big Caudron biplane, a rather slow but safe machine. This meant that Don Hale’s stay at the École Militaire de Beaumont was nearly at an end.

There were now but two tests before him, one known as the _petit voyage_ and the other the _grande voyage_. The first was a sixty mile trip and return; the second a triangular journey, each side being about seventy miles in length.

By the time Don had passed these successfully T. Singleton Albert and Victor Gilbert had gone to the great finishing school located at Pau, in the southern part of France.

It was indeed a happy moment to Don when he received his “_Brevet d’Aviateur Militaire_” from the War Department, which made him a corporal in the French army. This merely meant, however, that he had graduated from the school at Beaumont, and, like the two who had preceded him, was sent to take a course in “acrobatics” at Pau.

Pau, he found, was very delightfully situated, and within sight of the snow-capped Pyrenees.

With even added zest, Don Hale entered into the work before him. It was more dangerous than anything he had attempted in the school at Beaumont; but the tactics he learned were of extreme importance, being precisely those used in air fighting on the front.

About the middle of his course Don Hale was ordered to report to the Mitrailleuse school at Casso, on the shore of a lake, where soldiers in all branches of the army are trained in the use of machine guns. In a two-seater, piloted by another airman, Don Hale practiced firing at captive balloons and moving targets on the lake.

At first it proved very difficult, but constant work soon enabled him to meet the requirements of his instructors.

After the completion of this training he returned to Pau for a short period. Following this he went to Plessis Belleville to add a few final touches before being assigned to combat duty in one of the escadrilles.
