The Belgian helmet is khaki-colored, with the Belgian lion on the front; the Italian, greenish blue, with no insignia; the Serbian, khaki-colored, with the Serbian coat of arms; the Russian, khaki-colored, with the Russian coat of arms, and the Roumanian, blue-gray, with the Roumanian coat of arms. The French have made more than 12,000,000 helmets, using about 12,000 tons of steel. In other words, a ton of steel will make 1,000 helmets. The British also equipped their troops with a steel helmet, which has no ridge running from front to rear, as has the Adrian, no decorations, and a rather wide brim, which runs all the way round. It is of a khaki color. The Germans issued to a certain number of their men, generally those most exposed in trench fighting, a steel helmet considerably heavier than any of the allied helmets. It has a much higher crown, and comes down more over the eyes and the sides and back of the head. All these helmets are supported by means of a leather skull cap inside, which fitting closely to the head, distributes the weight over the whole of the skull, instead of simply around the edge of it, as is the case with ordinary headgear. Of course, these helmets will not protect against high velocity projectiles. However, as they do protect the wearer from low velocity projectiles, and as these are, because of infection, often as fatal as severe wounds, it can easily be seen how much good has been accomplished. A French writer in La Nature shows that 332 out of 479 abnormal wounds were caused by shrapnel and pieces of shell having a low velocity. In 13 out of 15 cases of lung wounds, the projectiles did not have velocity enough to completely traverse the body and come out. In 71 cases of joint wounds, 66 were due to low velocity shrapnel and only 5 to high velocity bullets. Practically every one of these wounds could have been prevented by breast and body pieces and knee and elbow caps of armor. LOW VELOCITY MOST EFFECTIVE. As for every man who afterward dies from a wound made by a high velocity bullet there are about ten who die from wounds made by the low velocity shrapnel and shell fragments, the importance is seen of protection against these low velocity wounds if it can be had. The wearing of armor means the lessening of the mobility of the soldier. In the open field lessening of mobility means a decrease in efficiency, which cannot be tolerated. However, in trench warfare the mobility of the individual does not count for so much, as even during an attack he does not have to go far, and generally does it at a walk in the rear of the barrage fire of his own artillery. Efficiency in warfare, as indicated by the keeping of such records, has set the brains of the world at work, and armor is used to a limited degree for the protection of men in greatly exposed fronts or open positions.
