But there were calculations to be made, which I set about with the eagerness which the occasion required, watching my Sergeant very closely as my head ran over its prospectus. And, first, if he stood by my side, I revolved, I could not by any chance whisper my tale to the silent bushes; although, if, at the favorable moment, when the squad was ordered to march, he but stepped a feather's-throw in advance of me, the confession could be readily made. His presence would frustrate my plans. There was one expedient at my beck, but quite hazardous, by the adoption of which against odds I might compass his death and my freedom,--a thought which I dismissed on the instant, as it savored of murder and ingratitude. I must trust that he would give me his back, in spite of his sense of responsibility, for a breathing-space ere we "fell in." With his fellow watch-dogs my ruminations had nothing to do. The nearest of them, owing to their scarcity, (and they had grown trebly valuable this campaign, as they had grown rarer,) was not within twenty yards of me. My new world was scarce that distance in the rear. The moment of all moments, the crisis, the vision of a life-time, eddying through the brain in the flash of a powder-pan, and stamping red-hot impressions there, (which in some cases bleach men's hair-roots,) was finally upon me. My Sergeant turned from me, and I glided with tiger-tread to the bushes, and laid myself down. I was, of course, between him and my new friends, and I pretended to sleep, so that, if he found me, he could scarce suppose that I meditated leaving him in so loose a manner; and, moreover, my being asleep would follow naturally upon my reiterated statement that I was sleepy. It would have been madness to have taken the other side, since, if there found, the case against me would have been clear. I depended, as is ever man's wont, upon mere shadows to do much for me where I was.
