The process of drainage is expensive, as compared with the price of land in our new settlements; but its cost will not alarm those who have been accustomed to see the improvements made in New England upon well cultivated farms. Compared with the labor and cost of building and maintaining FENCES upon the highways, and in the subdivisions of lots, common in the Eastern States, the drainage of land is a small matter. We see in many places long stretches of faced walls, on the line of our roads near towns and villages, which cost from two to five dollars per rod. Our common "stone walls" in these States cost about one dollar per rod to build originally; and almost any kind of wooden fence costs as much. Upon fences, there is occasion for annual repairs, while drains properly laid, are permanent. These suggestions are thrown out, that farmers may not be alarmed without cause, at the high cash estimates of the cost of drainage operations. Money comes slowly to farmers, and a cash estimate looks larger to them than an estimate in labor. The cost of fencing seems no great burden; though, estimated in cash, it would seem, as in fact it is, a severe charge. Drainage can be performed principally by the same kind of labor as fencing, the cost of the tiles being a small item in the whole expense. The estimates of labor will be made at one dollar per day, in investigating this matter. This would be the fair cash value of work by the day, perhaps; but it is far more than farmers, who have work in hand on their own farms, which may be executed in the leisure season after haying, and even into the Winter, when convenient, will really expend for such labor. Few farm operations would pay expenses, if every hour of superintendence, and every hour of labor by man and boy and beast, were set down at this high rate. The cost of the tiles will, ordinarily, be a cash item, and the labor may be performed like that of planting, hoeing, haying, and harvesting, by such "help" hired by the mouth or day, or rendered by the family, as may be found convenient. The cost of drainage may be considered conveniently, to borrow a clerical phrase, "under the following heads." 1. _Laying out, or Engineering._--In arranging our Spring's work, we devote time and attention to laying it out, though this hardly forms an item in the expense of the crop. Most farmers may think themselves competent to lay out their drainage-works, without paying for the scientific skill of an engineer, or even of a surveyor.
