This is doing half the work,—a very different thing from half-doing the work. In such cases, the lines should be laid out as though they were to be all done at once, and, finally, when the omitted drains are made, it should be in pursuance of the original plan. Probably the drains which are laid will produce more than one-half of the benefit that would result if they were all laid, but they will rarely be satisfactory, except as a temporary expedient, and the saving will be less than would at first seem likely, for when the second drains are laid; the cultivation of the land must be again interrupted; the draining force must be again brought together; the levels of the new lines must be taken, and connected with those of the old ones; and great care must be taken, selecting the dryest weather for the work,—to admit very little, if any, muddy water into the old mains. This practice of draining by installments is not recommended; it is only suggested as an allowable expedient, when the cost of the complete work could not be borne with out inconvenience. If any staid and economical farmer is disposed to be alarmed at the cost of draining, he is respectfully reminded of the miles of expensive stone walls and other fences, in New England and many other parts of the country, which often are a real detriment to the farms, occupying, with their accompanying bramble bushes and head lands, acres of valuable land, and causing great waste of time in turning at the ends of short furrows in plowing;—while they produce no benefit at all adequate to their cost and annoyance. It should also be considered that, just as the cost of fences is scarcely felt by the farmer, being made when his teams and hands could not be profitably employed in ordinary farming operations, so the cost of draining will be reduced in proportion to the amount of the work which he can "do within himself,"—without hiring men expressly for it. The estimate herein given is based on the supposition that men are hired for the work, at wages equal to $1.50 per day,—while draining would often furnish a great advantage to the farmer in giving employment to farm hands who are paid and subsisted by the year. CHAPTER VII. - "WILL IT PAY?" Starting with the basis of $60, as the cost of draining an acre of ordinary farm land;—what is the prospect that the work will prove remunerative? In all of the older States, farmers are glad to lend their surplus funds, on bond and mortgage on their neighbors’ farms, with interest at the rate of 7, and often 6 per cent. In view of the fact that a little attention must be given each year to the outlets, and, to the silt-basins, as well, for the first few years, it will be just to charge for the use of the capital 8-1/3 per cent. This will make a yearly charge on the land, for the benefits resulting from such a system of draining as has been described, OF FIVE DOLLARS PER ACRE.
