-- I am in the habit of going to all, and to Fairfax Seminary, Alexandria, and over Long Bridge to the great Convalescent Camp, &c. The journals publish a regular directory of them -- a long list. As a specimen of almost any one of the larger of these Hospitals, fancy to yourself a space of three to twenty acres of ground, on which are group'd ten or twelve very large wooden barracks, with, perhaps, a dozen or twenty, and sometimes more than that number, of small buildings, capable altogether of accommodating from five hundred to a thousand or fifteen hundred persons. Sometimes these wooden barracks or Wards, each of them, perhaps, from a hundred to a hundred and fifty feet long, are ranged in a straight row, evenly fronting the street; others are plann'd so as to form an immense V; and others again are ranged around a hollow square. They make altogether a huge cluster, with the additional tents, extra wards for contagious diseases, guard-houses, sutler's stores, chaplain's house, &c. In the middle will probably be an edifice devoted to the offices of the Surgeon in Charge, and the Ward Surgeons, principal attaches, clerks, &c. Then around this centre radiate or are gather'd the Wards for the wounded and sick. The Wards are either letter'd alphabetically, Ward G, Ward K, or else numerically, 1, 2, 3, &c. Each has its Ward Surgeon and corps of nurses. Of course, there is, in the aggregate, quite a muster of employes, and over all the Surgeon in Charge.
The newspaper reader off through the agricultural regions, East or West, sees frequent allusions to these Hospitals, but has probably no clear idea of them. Here in Washington, when they are all fill'd, (as they have been already several times,) they contain a population more numerous in itself than the whole of the Washington of ten or fifteen years ago. Within sight of the Capitol, as I write, are some fifty or sixty such collections or camps, at times holding from fifty to seventy thousand men. Looking from any eminence and studying the topography in my rambles, I use
