Formerly I built stone foundations on which were placed the buildings, cementing the stone work to the sill carefully inside and out. This proved in the end not only an expensive but a very unsatisfactory arrangement, for cement it as one would the action of the frost would always part the sill from the foundation and admit the cold air from all around just where it should be kept warm. I have since hit upon a plan which has not only met the case but is comparatively inexpensive. Place posts, with one square side to them, about four feet apart, on which place the 2x4 inch sill. Set these posts in the ground so that the tops rise but one inch above the surface, with the flat side exactly horizontal and perpendicular to the inside of the sill. Then sink a hemlock board twelve or fourteen inches wide into the ground inside of the building, and immediately in front of the two-inch sill, until the upper edge is flush with the upper side of the sill, nailing it firmly thereto, filling up inside nearly to a level of the top of the sill. This gives a warm, cheap foundation on which the frost does not act. Hemlock, too, seems to have an affinity for moisture and will last in that condition from eight to ten years, when it can be easily renewed. This arrangement is also comparatively rat-proof, as a hemlock board is a rat's aversion. It does not agree with their teeth. They cannot possibly dig under during the frozen months of the year, and as it affords them no concealment they do not care to, during the warm season. The Outside Plan of a Breeding and Brooding House with the exception of a little more glass in the latter, should be precisely the same both for ducks and ducklings. The internal arrangements can be made to suit. As I shall give a full description with cuts of this building later, I will now merely give the manner in which it should be arranged as a good breeding-house for ducks. This building should be fifteen feet wide and any length required. It should have an uneven double roof, five-foot posts in the rear and four foot in front. About one-quarter of this front should be glass. There should be a walk the entire length of the building three and one-half feet wide. The main body of the building should be divided into pens twenty feet long, by either lath or wire two feet high.
