=The Battalion Bombers’ Section.= The Battalion Bombers’ Section, when complete, should consist of about 40 trained men, including N.C.O.’s, but the training of all men should be proceeded with so that ultimately every man in the battalion is qualified. When trained a thrower should be able, when standing in a trench behind one traverse, to place 75 per cent. of his bombs in a bay on the farther side of a traverse 30 yards away. To be an expert bomber, one must be fit. It is therefore necessary to take a certain amount of physical exercise each day while in training and when on active service. In this respect the grenadiers are especially cared for. They are given special privileges, given the best of billets and shorter hours in the trenches, which gives them plenty of time for exercise, and their favorite games, which keeps them in good condition. Drinking is not prohibited, but if a man expects to be able to keep cool and think and act quickly it is better to be temperate. A bombers’ duties in the trenches are looked upon as most interesting and lack monotony. If he understands his work and the grenades, that is, when they are safe, he has nothing to fear, although he will find that some of his more ignorant pals may shun him when he goes about with his full complement, in fact, they will make way wherever he goes. When our First Canadian Division went into the trenches, as also have many other reinforcing battalions, without a sufficient knowledge of bombs, the result was that many accidents occurred through carelessness and ignorance and lack of training in this important branch of work. =Practice in Making and Throwing of Dummy Bombs.= In order that the men may become proficient in the matter of throwing live bombs it is necessary to have dummies which represent as nearly as possible in size, shape and weight the live manufactured types which are used in active service. The men are accordingly taught to make these by hand. There are four types of these, as follows:-- (a) =The Jam-Tin Dummy=, which is made with an empty jam tin, three-quarters filled with clay, the top being drawn together and sewn with wire. This type contains no explosives. (b) A jam-tin made in the same manner but in the centre of the tin is placed half a cartridge of monobel with fuse and cap. These two types of bombs are made to weigh from one to two and a quarter pounds, and may be thrown from thirty to fifty yards.
