Owing to war conditions, it was difficult to find a font of type satisfactory for beginners and the compiler is aware of the deficiencies of some of the lettering herein used, His warmest thanks are due to Messrs. V. V. Kister and Clarence A. Manning for their assistance in reading the proof of the exercises, and to Mr. Bozo Rankovich for his patient labor under many difficulties in printing the work.
