negligent he is about writing or how long delayed his replies are, I am always quite sure when I receive his letter that when he wrote it he had my last communication before him. He catches my subtlest joke, he responds to my mood, whatever it may have been, as surely as he would have done were we together, and my slightest inquiry never goes unnoticed or unanswered. His letters seem to me almost as satisfying as if we were talking face to face. The difference between these two men was very little in temperament or in training; they were about the same age, they were educated similarly; it was largely a matter of knowing how to write a letter, of appreciating what will interest and hold the attention of one's friends. One kept his readers in mind when he was writing; the other thought very largely of his own personal feelings.
First of all it is well to remember that when people of approximately the same age are writing to each other, unless their main interests are technical or professional, the thing they want most to hear about is each other's movements. Protestations of love and undying friendship are all right
