We arrived in Knoxville shortly after noon, and marched through the hot, dusty streets, directly to the old jail. This is now a historical edifice. It will forever remain associated with the extreme sufferings of the loyal East Tennesseeans, during the progress of the great rebellion. The building itself is a noble one, and resembles some old baronial hall. It is of a peculiar style of architecture--solid, square and massive, with lofty projecting towers and sharp angles--altogether presenting an imposing appearance. It was used as a military prison, and was filled from top to bottom with ragged, dirty-looking prisoners. Some were Union men, and others were deserters from their own rebel ranks. These constituted the _lower_ class of prisoners, and were permitted to range over most of the building, which was completely encircled outside by a strong guard. The higher class, or those who were charged with more desperate offences, were shut up in cages. There were five of these. Two of them were at once cleared for our reception. The smaller one was about seven feet by nine, and four of us were put into it. The larger, in which the remainder of the party were placed, was perhaps ten by twelve. The latter was the cage in which Parson Brownlow had been confined, and we felt honored by being in the same cell that this noble champion of the Union had once occupied. While in this cage, we read an article in a copy of the _Knoxville Register_, stating that Brownlow was in the North, humbugging the Yankees by telling them that he had been kept in an iron cage, and fired at by his guards, when everybody in that vicinity knew that the whole thing was a falsity. Even while we read this, we looked at the shot-marks which were still visible on the cage, and which the guards and prisoners assured us had been made in the way Brownlow stated. This may serve as a specimen of the manner in which Southern papers are accustomed to deal with facts. It was in the latter part of May when we arrived in Knoxville, and _outside_, the weather was intensely warm, but _inside_, from the enormous masses of stone and iron around, it was quite cool. Indeed the nights, which are always cool, even in midsummer, in the warmest parts of the South, were here very cold, and as we had no beds or blankets, but had to lie on the partly iron floor, we suffered greatly.
