Leave no places open for surface-water to run in; that would soon fill up and ruin a drain. Drains made to carry off spring-water are often useless by being in a wrong location. Springs come out near the foot of rising ground. Just where they come out should be the location of the drain, which would then carry off the water and prevent it from saturating and chilling the soil in the field below. Many persons locate their ditch down in the centre of the wet level below the rise of ground; this is of no use to the surface above, to the point where the water springs. Locate the drain just at the point where the land begins to be unduly wet. On very wet, level land, a small drain may also be needed below the first and main one. The cost of a covered drain as described above will be from fifty to seventy-five cents per rod, and an uncovered one will cost from twenty to thirty cents. When you have low swamps to drain, you can realize more than the cost of draining, by carting the excavations upon other land, or into the barnyard as material for compost. Perhaps no expenditure, on land needing it, pays so well as thorough draining. It is important, for all fruit-orchards on low land, to put a drain through under each row of trees: it is indispensable to cherries, and highly favorable to all other fruits. DUCKS. There are a number of varieties, the wild Black Spanish, the Canvass-Back, and the ordinary little duck of the farmyard, are all good. The common duck is the only one we recommend for the American poultry-yard. A close pasture, including a rivulet, or a small stream of water, affords facilities for raising ducks at a cheap rate. From one hundred to one thousand ducks may be raised in such an enclosure of an acre or two, quite profitably. If there is plenty of grass, they will still need a little grain. In the winter the cheapest feed is beets or potatoes cut fine, with a very little grain. Each duck, well kept, will lay from fifty to one hundred eggs, larger than hen's eggs, and about as good for cooking purposes. They may be picked as geese, for live feathers, though not quite so frequently. The feathers will nearly pay for keeping, leaving the eggs and increase as profit. DWARFING.
