_My Success._--I judge that there are not many tracts more difficult to drain than mine was, considering all the circumstances, except those which are frequently flowed by tides or the waters of some lake, or river. Had I owned the entire swamp, or had there been a fall in the brook just below me, had I had any prior experience in draining, or had others equally interested cooperated in the good work, my task would have been comparatively light. As it was, I made mistakes which increased the cost and postponed the success of my efforts; but this is at length complete. I had seven acres of Indian Corn, one of Corn Fodder, two of Oats, and seven or eight acres of Grass, on my lowland in 1869; and, though the Spring months were quite rainy, and the latter part of Summer rather dry, my crops were all good. I did not see better in Westchester County; and I shall be quite content with as good hereafter. Of my seven hundred bushels of Corn (ears,) I judge that two-thirds would be accounted fit for seed anywhere; my Grass was cut twice, and yielded one large crop and another heavier than the average first crop throughout our State. My drainage will require some care henceforth; but the fifteen acres I have reclaimed from utter uselessness and obstructions are decidedly the best part of my farm, Uplands may be exhausted; these never can be. The experience of another season (1870) of protracted drouth has fully justified my most sanguine expectations. I had this year four acres of Corn, and as many of Oats, on my swamp, with the residue in Grass; and they were all good. I estimate my first Hay-crop at over two and a half tuns per acre, while the rowen or aftermath barely exceeded half a tun per acre, because of the severity of the drouth, which began in July and lasted till October. My Oats were good, but not remarkably so; and I had 810 bushels of ears of sound, ripe Corn from four acres of drained swamp and two and a half of upland. I estimate my upland Corn at seventy (shelled) bushels, and my lowland at fifty-five (shelled) bushels per acre. Others, doubtless, had more, despite the unpropitious season; but my crop was a fair one, and I am content with it. My upland Corn was heavily manured; my lowland but moderately. There are many to tell you how much I lose by my farming; I only say that, as yet, no one else has lost a farthing by it, and I do not complain. XI. DRAINING GENERALLY. Having narrated my own experience in draining with entire unreserve, I here submit the general conclusions to which it has led me:
