When Robert Louis Stevenson and Edward Livingston Trudeau spent days together at Dr. Trudeau's Adirondack sanitarium--the one as patient, the other as physician--they proved that true comradeship is possible even when men's tastes are most unlike. It was possible because they knew how to ignore differences and to find common ground in the worth-while things. "My life interests were bound up in the study of facts, and in the laboratory I bowed duly to the majesty of fact, wherever it might lead," Dr. Trudeau wrote. "Mr. Stevenson's view was to ignore or avoid as much as possible unpleasant facts, and live in a beautiful, extraneous and ideal world of fancy. I got him one day into the laboratory, from which he escaped at the first opportunity.... On the other hand, I knew well I could not discuss intelligently with him the things he lived among and the masterly work he produced, because I was incompetent to appreciate to the full the wonderful situations his brilliant mind evolved and the high literary merit of the work in which he described the flights of his great genius." Yet these two men were great companions, for in spite of differences as to details, their hopes and ambitions and ideals all pointed to the best things in life. After the author's departure, he sent to the doctor a splendidly bound set of his works, first writing in each volume a whimsical bit of rhyme, composed for the occasion. Though all of these men were real comrades, there is a higher manifestation of comradeship than this. This was shown in the relation of Daniel Coit Gilman, later President of Johns Hopkins University, when he wrote to a fellow student of the deepest things in his life: "I don't wish merely to thank you in a general way for writing as you did an expression of sympathy, but more especially to respond to the sentiments on Christian acquaintance which you there bring out. I agree with you most fully and only regret that I did not know at an earlier time upon our journey what were your feelings upon a few such topics. I tell you, Brace, that I hate cant and all that sort of thing as much as you or anyone else can do. It is not with everyone that I would enjoy a talk upon religious subjects. I hardly ever wrote a letter on them to those I know best. But when anyone believes in an inner life of faith and joy, and is willing to talk about it in an earnest, everyday style and tone, I do enjoy it most exceedingly."
