Tramp steamers are numerous, on these lower reaches. We have seen perhaps a dozen such to-day, stopping at the farm landings as well as at the crude and infrequent hamlets,--mere notches of settlement in the wooded lines of shore,--doing a small business in chance cargoes and in passengers who flag them from the bank. A sultry atmosphere has been with us through the day. The glassy surface of the river has, when not lashed into foam by passing boats, dazzled the eyes most painfully. The hills, from below Stewart's Island, have receded on either side, generally leaving either low, broad, heavily-timbered bottoms, or high clay banks which stretch back wide plains of yellow and gray corn-land--frequently inundated, but highly productive. Now and then the encroaching river has remained too long in some belt of forest, and we have great clumps of dead trees, which spring aloft in stately picturesqueness, thickly-clad to the limb-tips with Virginia creeper. A bit of shaly hillside occasionally abuts upon the river, though less frequently than above; and often such a spur has lying at its feet a row of half-immersed boulders, delicately carpeted with mosses and with clinging vines.
The Tennessee River (918 miles), the largest of the Ohio's tributaries, is, where it enters, about half the width of the latter. Coming down through a broad, forested bottom, with several pretty islands off its mouth, it presents a pleasing picture. Here again the government has been obliged to put in costly works to stop the ravages of the mingling torrents in the soft alluvial banks. The Ohio, with the united waters of the Cumberland and the Tennessee, henceforth flows majestically to the Mississippi, a full mile wide between her shores.
Paducah (13,000 inhabitants), next to Louisville Kentucky's most important river port, lies on a high plain just below the Tennessee. It is a stirring little city, with the usual large proportion of negroes, and the out-door business life everywhere met with in the South. Saw-mills, iron plants, and ship-yards line the bank; at the wharf are large steamers doing a considerable business up the Cumberland and Tennessee, and between Paducah and Cairo and St. Louis; and there is a considerable ferry business to and from the Illinois suburb of Brooklyn.
