We had now passed over a long tract of river navigation since we embarked at Pittsburgh. Our eyes had become almost wearied with tracing first the endless sylvan beauties that clustered around the banks of the smooth-flowing Ohio; and then the vast, unpenetrated, boundless forest scenes that spread away on either side of us from the abrupt, muddy banks of the Mississippi. Our ear had become wearied with the monotony of the sharp, rough sound of the high-pressure engine, that was heard ceaselessly day and night. Books scarcely any longer could interest us. The character and conversation of most of those around us seemed exceedingly dull and common-place. There was however one exception. This was found in the person of one of our passengers--a man of almost herculean stature, who, we soon learned, possessed great versatility and vigour of mind. His manners, however, at first appeared so coarse, and his conversation so blunt, that there seemed something exceedingly repulsive connected with his character. But this impression soon wore away, and in a few days he became the centre of almost universal attraction. He was a true Kentuckian of the old school; he was born and brought up amid the stirring scenes connected with the early settlement of his native state, and was perfectly familiar with all the war legends, and every bloody fray from the first movement of Col. Boone to the final expulsion of all the savage tribes from this their ancient hunting ground. To use his own language, he was "born in an Indian fort, and through childhood fed upon bear's meat, and clothed in buffalo skins." His physical strength seemed enormous, and he bore evident marks of being one of those brave, reckless characters that find pleasurable excitement in facing danger and death in every form. Yet he was not destitute of the softer and more kindly feelings of our nature, and withal seemed to have a high and reverential regard for religion. It was now just at the close of a long summer's day. Our steamer for many a long weary hour had been pushing her slow course up the broad current of the Mississippi, when there suddenly opened upon us a vast, far-extending prairie. To me this was an object of thrilling interest, and the more so because hitherto we had seen scarcely nothing upon either side of the river but unbroken and boundless forests, stretching away as far as the eye could reach to the distant horizon. But here was a vast expanse in which no tree, nor stump, nor stone was visible. Naught met the eye but the tall grass, waving in the breeze, bending, rising, and rolling to and fro like the waves of the ocean after a tempest; and this grassy surface interspersed with wild flowers of every colour, hue and form.
