_My Difficulties._--This marsh or bog consisted, when I first grappled with it, of some thirty acres, whereof I then owned less than a third. To drain it to advantage, one person should own it all, or the different owners should cooperate; but I had to go it alone, with no other aid than a freely accorded privilege of straightening as well as deepening the brook which wound its way through the dryer meadow just below me, forming here the boundary of two adjacent farms. I spent $100 on this job, which is still imperfect; but the first decided fall in the stream occurs nearly a mile below me; and you tire easily of doing at your own cost work which benefits several others as much as yourself. My drainage will never be perfect till this brook, with that far larger one in which it is merged sixty rods below me, shall have been sunk three or four feet, at a further expense of at least $500. This bog or swamp, when I first bought into it, was mainly dedicated to the use of frogs, muskrats and snapping-turtles. A few small water-elms and soft maples grew upon it, with swamp alder partly fringing the western base of the hill east of it, where the rocks which had, through thousands of years, rolled from the hill, thickly covered the surface, with springs bubbling up around and among them. Decaying stumps and imbedded fragments of trees argued that timber formerly covered this marsh as well as the encircling hills. A tall, dense growth of blackberry briers, thoroughwort, and all manner of marsh-weeds and grasses, covered the center of the swamp each Summer; but my original portion of it, being too wet for these, was mainly addicted to hassocks or tussocks of wiry, worthless grass; their matted roots rising in hard bunches a few inches above the soft, bare, encircling mud. The bog ranged in depth from a few inches to five or six feet, and was composed of black, peaty, vegetable mold, diversified by occasional streaks of clay or sand, all resting on a substratum of hard, coarse gravel, out of which two or three springs bubbled up, in addition to the half a dozen which poured in from the east, and a tiny rivulet which (except in a very dry, hot time) added the tribute of three or four more, which sprang from the base of a higher shelf of the hill near the middle of what is now my farm. Add to these that the brook which brawled and foamed down my hill-side near my south line as aforesaid, had brought along an immensity of pebbles and gravel of which it had mainly formed my five acres of dryer lowland, had thus built up a pretty swale, whereon it had the bad habit of filling up one channel, and then cutting another, more devious and eccentric, if possible, than any of its predecessors--and you have some idea of the obstacles I encountered and resolved to overcome. One of my first substantial improvements was the cutting of a straight channel for this current and, by walling it with large stones, compelling the brook to respect necessary limitations. It
