And nightly Reardon sits on his cot and writes in the dim light careful answers to every message. Lucy and Corder are putting themselves to bed most systematically, Corder because of his middle-aged habit, Lucy on account of that aristocratic cleanliness in which he has been scrupulously bred. They have their system and their order, the toilet, the costume, the making of the bed, all very careful and precise. Knudsen, still dressed, is lolling on his cot and jollying; this is the time of day when he most comes out of himself, and I know that presently when I approach the tent it will be his ringing tenor that I shall hear. He is poking fun at the others, cursing that last shot on the range, interrupting Reardon and Clay in their writing, philosophizing on his favorite subject, baseball. Yet if you get a little closer to him you find that he has interests that it takes a little coaxing to disclose: religious convictions that he has changed with his growth, curious hard business experiences that make him declare that he is a self-seeker, while you have only to watch him with Lucy to know that he is not. Yet he sedulously knocks and batters at every feminine quality that the boy discloses, and will exaggerate any statement if he thinks you suspect him of tenderness. I shall presently make a dash, for the tent, snatch my tooth-brush and make for the spigot, and bring back a basin of water for my feet. Then Knudsen will bestir himself and race me for bed, at the same time that Reardon lays by his pen and accepts our warning. We crawl between the blankets, nine over us tonight. I shall put my poncho over me next, and my overcoat on that, and with the tent-wall looped up shall be practically outdoors. Last of all Pickle will come slipping in from some rendezvous with friends. He sleeps in his clothes, minus shoes and leggings, and he is likely to be curled up before I am. And then float to us the notes of Taps. "Love, good night. Must thou go...?" It is the signal. The last one of us puts out the lantern, and it is soon "Good night, boys," and silence. Usually I go to sleep at once; if not I soon hear the feet of two of the sergeants in the street and see the gleam of their lantern. They come from tent to tent, enter ours and throw the light on each cot, and pass on. Often I hear from the neighboring tents a sleepy "Good night, sergeant," but never yet the question "Who sleeps in that cot?" A high average, then, of obedience to the rules. The men are here for business. I have lingered almost too long. Good night! DICK. THE SAME TO THE SAME Plattsburg, 20th Sept., 1916. DEAR MOTHER:--
