But we need not go so far. What is that monument in Greenwood? It is to the doctors who fell in the Southern epidemics. Why go? Were there not enough sick to be attended in these Northern latitudes? Oh, yes; but the doctor puts a few medical books in his valise, and some vials of medicine, and leaves his patients here in the hands of other physicians, and takes the rail-train. Before he gets to the infected regions he passes crowded rail-trains, regular and extra, taking the flying and affrighted populations. He arrives in a city over which a great horror is brooding. He goes from couch to couch, feeling of pulse and studying symptoms, and prescribing day after day, night after night, until a fellow-physician says: "Doctor, you had better go home and rest; you look miserable." But he can not rest while so many are suffering. On and on, until some morning finds him in a delirium, in which he talks of home, and then rises and says he must go and look after those patients. He is told to lie down; but he fights his attendants until he falls back, and is weaker and weaker, and dies for people with whom he had no kinship, and far away from his own family, and is hastily put away in a stranger's tomb, and only the fifth part of a newspaper line tells us of his sacrifice--his name just mentioned among five. Yet he has touched the furthest height of sublimity in that three weeks of humanitarian service. He goes straight as an arrow to the bosom of Him who said: "I was sick and ye visited Me." Life for life. Blood for blood. Substitution! In the legal profession I see the same principle of self-sacrifice. In 1846, William Freeman, a pauperized and idiotic negro, was at Auburn, N.Y., on trial for murder. He had slain the entire Van Nest family. The foaming wrath of the community could be kept off him only by armed constables. Who would volunteer to be his counsel? No attorney wanted to sacrifice his popularity by such an ungrateful task. All were silent save one, a young lawyer with feeble voice, that could hardly be heard outside the bar, pale and thin and awkward. It was William H. Seward, who saw that the prisoner was idiotic and irresponsible, and ought to be put in an asylum rather than put to death, the heroic counsel uttering these beautiful words:
