 *mental, and attached to the brigade. Two guns under an officer form the subdivision of his command, and can be detached at will, but no machine gun is ever employed singly. The guns are usually kept at the disposal of the brigadier, and have been used more in defence than attack; they seldom open at long ranges unless on an exceptionally good target. It is rather the rule to reserve the machine-gun fire for decisive ranges. In many actions which cavalry officers described to me, the practice has been to allow the enemy to come within 600 yards before opening fire, and then suddenly to overwhelm him. The principle with such well-trained troops is sound, for the moral "knock-out" of a 10-per-cent. loss suffered in a few minutes is far greater than a similar loss spread over the advance from 1,000 to 600 yards, and the expenditure of ammunition is less. Concealment is an essential feature of the Japanese machine-gun tactics, and the officer told me he had not a single gun put out of action by opposing artillery. The guns have shields; the manipulators of the machine guns are very expert, and there is now seldom a jam. Like a good chauffeur, the Japanese machine gunner knows all the peculiarities of the weapon he fires, and can almost tell by instinct when anything is going wrong. Four thousand rounds is the most that has been fired in a day by three machine guns of the 1st Cavalry Brigade; the number is now increased to six. Throughout
