THE principal camp of engineers preparing for service abroad is situated in Moore Park, but most of the active service work is done in Centennial Park. The men are commanded by Colonel Spain, V.D., with Captain A. J. Arnot as camp adjutant, Lieutenant Calder as chief instructor, and Lieutenant E. A. Cottee as quartermaster. The engineers' school of instruction is under Lieutenant (Professor) Nadsen, assistant professor of electrical engineering at Sydney University, whose staff includes many men prominent in the engineering world of Australia. None but proficient mechanics —artisans in the truest sense of the word— have a chance of being attached to the Australian Engineers. There are many skilled carpenters, as well as plumbers, builders, bricklayers, ironworkers, and last, but not least, electrical students. These men are more than soldiers— they are engineers. Included in their equipment is that of the infantryman— rifle, bayonet, etc. But there is also other equipment, of which too much must not be said. The Sydney camp is constantly receiving units from the other States, who come to Moore Park for the finishing course of their training.
