The men must be taught to estimate distances both from themselves to a given point and between two points, both at some distance from them. The latter is necessary in their patrol work in estimating lengths of column and frontages occupied. If the estimating be conducted in this way the weather will make little difference; the men dress suitably for it and are out only a short time. The work to be of value must be done under varying conditions of light. There should be no week in the year in which this exercise is not conducted. In summer it should be done on the days when the company is away from the garrison on the weekly practice march; there is ample time for it during the long halt. This work can be conducted so as only to take about fifteen minutes of each man’s time per week. It is well worth it. I have seen the above plan carried out intelligently in two or three companies and the results were remarkably good; the ability of the men to estimate distance was better than that given for musketry school graduates in foreign services. On the other hand I have seen it indifferently carried out and, like most indifferent work, it was a waste of time. [Sidenote: Position and aiming drills, gallery practice] Position and aiming drills and gallery practice must be a weekly occurrence and holding them twice a week will be better. If the detachments are made small enough gallery practice requires but little time for each man. It is important in conducting this practice to see that no man ever fires a score in a careless or indifferent manner; if this is permitted the result obtained will be the opposite of that desired. I found one very effective means of preventing such careless work: a man found guilty of careless firing was required to repeat his score—but not at that time when it would delay the regular course. He had to remain near the gallery until I, or someone designated by me, came around to supervise his firing and it was usually some little time before I got around. [Sidenote: Bayonet fencing] Throughout the year careful attention should be given to bayonet fencing. I do not believe that there is much probability of a bayonet contest in war but, for psychological reasons, this training is necessary. Positions are carried by the bayonet, but past experience shows that in such charges the bayonets seldom crossed and when they did it was a “rough and tumble.” Our men may go in with the best intentions in the world to use the bayonet according to rule, yet the chances are that, in the excitement of the mélee, habit will assert itself and the gun become a bat. Nevertheless, troops are very seldom “shot out of a position”; the imminent threat of the bayonet is necessary; but, as the opposing bayonets get close, one side or the other weakens.
