=Organization.= The use of bombs was adopted by the British War Office early in the summer of 1915. The organization put into effect in England was as follows: In each brigade was formed what was known as the Brigade Bombers’ Company. Men were detailed from each of the units forming the brigade for their initial training, which lasted over a period of six days. During the first of the training periods at least one subaltern per battalion should be attached to the Brigade Company for training, so that the battalion is provided with an officer qualified to superintend the training of the battalion bombers’ section. This officer and others should return to the brigade company for short periods of training from time to time as it has been found that new technical as well as tactical ideas are continually being introduced into this important branch of work. One sergeant, two corporals and 32 rank and file are detailed from each battalion. The company is commanded by a selected officer, who will be assisted by an additional N.C.O., who acts in the capacity of C.S.M. and C.Q.M.S. The Company is kept up to strength by a system of relays, so that at the end of each three days half the men of the Company are returned to their units for duty, their place being taken by others detailed for that purpose. It will be seen that by this method in a short time the entire brigade will have received their preliminary training in this subject. It must not be considered that their training in bombing is complete at the end of six days, further periods for practices being arranged for in their weekly training syllabus. The preliminary training having been completed, there is formed what was known as a permanent Brigade Bombers’ Company.
