Mars laughed. "Why," said he, "I'm more than half Southern; born in North Carolina, and spending much of my boyhood there at mother's old home. They used to call me 'reb' the whole time I was a cadet. It is a wonder I wasn't an out-and-out 'reb' too. All mother's people were, and they never have been reconciled to her for sticking to father and his side of the question. Poor little mother," he added, while the tears gathered in his eyes, "she _is_ alone in the world if ever woman was, and I sometimes wonder if I ought not to yield to her wishes and go and be a clerk of some kind." All the glow, all the life that possessed him as he came in fresh from the exercise of his drill seemed to have left Mars by this time. He was profoundly sad and depressed. That was plainly to be seen. Hoping to find something as a distraction to his gloomy reflections, I called his attention to the mail that had arrived during his absence. He moved negligently towards the desk, raised the handkerchief with weary indifference, and glanced at the packet underneath. Instantly his whole manner changed; the color sprang to his face; his eyes flamed, and a nervous thrill seemed to shoot through his frame. Paying no attention to the others, he had seized the dainty missive that so excited my curiosity, and with a hand that plainly shook tore it open, turned his back to me with the briefest "Excuse me one minute," and was speedily so absorbed in the letter that he never noticed me as I rose and strolled out to the front of the tent and the bright wintry sunshine beyond. The boy needed to be alone. Fully fifteen minutes passed by before he rejoined me, coming out with a quick, nervous step, and a face that had grown white and almost old in that time. What _could_ be wrong with him? "Mr. Brandon, I beg your pardon for being so inhospitable. My letters were important, and--and rather a surprise, one of them. It is just about noon. May I offer you a toddy? It's the best I can do." Mr. Brandon, to the scandal of his principles, decided that on this occasion he would accept the proffered refreshment. It seemed to be a relief to Mars. He bustled about, getting sugar and glasses and some fresh spring water; then speedily tendering me a goblet, produced a black bottle from his trunk. "Shall I pour for you?" said he. "Say when." And in a moment the juice of the rye and other less harmful ingredients were mingled with the sweetened water. "You will excuse me," said he. "I never touch it, except--well, that drink I took the night on the train after our tussle with Smith is the only one I've taken since I joined the troop. I promised mother, Mr. Brandon."
