Nashville, Friday, Feb. 10. Last night I had another visit from that evil genius that seems to hover over my very existence, the ague: I shook briskly for about an hour and a half, but it was not followed by a very heavy fever. Got up to breakfast. Found that Keeler had called my name for supernumerary guard. I did not feel able for duty, but as the boys have such heavy duty on every other day, I could not refuse to do all I could, so I went and drew me a musket and turned out to guard-mount. Oh! how ferocious I did look with my brass plates and fixed bayonet. Griff gone to town on guard. The mail has just brought me a letter from John which says Mother is improving, but yet suffering severely.
