We left Beaufort, S. C., on the afternoon of July 9th, 1863. In former narrations I have sufficiently described the charm of a moonlight ascent into a hostile country, upon an unknown stream, the dark and silent banks, the rippling water, the wail of the reed-birds, the anxious watch, the breathless listening, the veiled lights, the whispered orders. To this was now to be added the vexation of an insufficient pilotage, for our negro guide knew only the upper river, and, as it finally proved, not even that, while, to take us over the bar which obstructed the main stream, we must borrow a pilot from Captain Dutch, whose gunboat blockaded that point. This active naval officer, however, whose boat expeditions had penetrated all the lower branches of those rivers, could supply our want, and we borrowed from him not only a pilot, but a surgeon, to replace our own, who had been prevented by an accident from coming with us. Thus accompanied, we steamed over the bar in safety, had a peaceful ascent, passed the island of Jehossee,--the fine estate of Governor Aiken, then left undisturbed by both sides,--and fired our first shell into the camp at Wiltown Bluff at four o'clock in the morning. The battery--whether fixed or movable we knew not--met us with a promptness that proved very short-lived. After three shots it was silent, but we could not tell why. The bluff was wooded and we could see but little. The only course was to land, under cover of the guns. As the firing ceased and the smoke cleared away, I looked across the rice-fields which lay beneath the bluff. The first sunbeams glowed upon their emerald levels, and on the blossoming hedges along the rectangular dikes. What were those black dots which everywhere appeared? Those moist meadows had become alive with human heads, and along each narrow path came a straggling file of men and women, all on a run for the river-side. I went ashore with a boat-load of troops at once. The landing was difficult and marshy. The astonished negroes tugged us up the bank, and gazed on us as if we had been Cortez and Columbus. They kept arriving by land much faster than we could come by water; every moment increased the crowd, the jostling, the mutual clinging, on that miry foothold. What a scene it was! With the wild faces, eager figures, strange garments, it seemed, as one of the poor things reverently suggested, "like notin' but de judgment day." Presently they began to come from the houses also, with their little bundles on their heads; then with larger bundles. Old women, trotting on the narrow paths, would kneel to pray a little prayer, still balancing the bundle; and then would suddenly spring up, urged by the accumulating procession behind, and would move on till irresistibly compelled by thankfulness to dip down for another invocation. Reaching us, every human being must grasp our hands, amid exclamations of "Bress you, mas'r," and "Bress de Lord,"
