 *mal units must be broken up. In large battles the brigade is the largest force which may yet be employed as an intact unit, although the employment of infantry by regiments will continue to be the rule. Brigade commanders are necessary for decreasing units of command and desirable for relieving the division commanders of a part of their work. In time of peace brigade commanders are useful for directing recruitment and, moreover, as connecting links between regiments and the division. The unmistakable advantages of the three-battalion organization have induced the United States to form its brigades of three regiments, each of three battalions (of 400 men each). An English division consists of three brigades of four battalions each.

4. INTRENCHING TOOL EQUIPMENT.

Earth as a covering material and, incidental thereto, the adoption of the small spade after the Russo-Turkish war, have increased in importance owing to the greater penetrating power of the modern infantry bullets. The disadvantages of the spade lie in the danger of its being misused and in the consequent impairment of offensive spirit. There is, moreover, danger that the fire effect will be impaired and subordinated to considerations of cover. The spade should therefore not be employed on every occasion, but only when the tactical purpose in view requires it.

What the weight of the portable intrenching equipment of the Japanese, Russian, and British infantry will be, is still undecided, but experiments are being made with a uniform tool. When we consider, that for the purpose of intrenching, one man requires a space of 1.20 m., and for handling his rifle a space of 0.8 m., and that when intrenching under fire all the men cannot work, it is obvious that it would be im-*
