The medical department of an army, like every other, is controlled by a _system_, and it is this which regulates its connections with the soldier more than the qualifications of individual surgeons. In the army the _system_ takes care of everything, even to the minutest details. Hygienic regulations for preserving the salubrity of camps and the cleanliness of the troops and their tents, are prescribed and enforced. Every day there is a 'sick call' at which men who find themselves ill present themselves to the surgeons for treatment. If slightly affected, they are taken care of in their own quarters; if more seriously, in the regimental hospitals; if still more so, in the large hospitals established by the chief medical officer of the corps; and if necessary, sent to the Government hospitals established at various places in the country. To the latter almost all the sick are transferred previous to a march. To be ill in the army, amid the constant noises of a camp, and with the non-luxurious appliances of a field hospital, is no very pleasant matter; but the sick soldier receives all the attention and accommodation possible under the circumstances. To every corps is attached a train of ambulances, in the proportion of two or three to a regiment. They are spring wagons with seats along the sides, like an omnibus, which can, when necessary, be made to form a bed for two or three persons. With each train is a number of wagons, carrying tents, beds, medicine chests, etc., required for the establishment of hospitals. On the march, the ambulances collect the sick and exhausted who fall out from the columns and have a surgeon's certificate as to their condition. When a battle is impending, and the field of conflict fixed, the chief medical officers of the corps take possession of houses and barns in the rear, collect hay and straw for bedding, or, if more convenient, pitch the tents at proper localities. A detail of surgeons is made to give the necessary attendance. While the battle proceeds, the lightly wounded fall to the rear, and are there temporarily treated by the surgeons who have accompanied the troops to the field, and then find their way to the hospitals. If the fighting has passed beyond the places where lie the more dangerously wounded, they are brought to the rear by the 'stretcher bearers' attached to the ambulance trains, and carried to the hospitals in the ambulances. Sometimes it happens that the strife will rage for hours on nearly the same spot, and it may be night before the 'stretcher bearers' can go out and collect the wounded. But the surgeons make indefatigable exertions, often exposed to great danger, to give their attention to those who require it. At the best, war is terrible--all its 'pomp, pride, and circumstance' disappear in the view of the wounded and dead on the field, and of the mangled remnants of humanity in the hospitals. But everything that can be devised and applied to mitigate its horrors is
