. Artificial incubation and incubators ... pto the twenty-fifth day. The next experiment I give was virtually a continuation of thefirst. The same Leghorn pullet, after having been with a Brahmacockerel three days, was penned with a cockerel of her own kind.

Six eggs after this, to the fourteenth, wereset, the twelfth and thirteenth only hatching, and both were with-out any apparent cross of Brahma blood. A second experiment ofthe same kind with a Houdan hen, crossed with a Leghorn cock-erel, and then put with a Houdan cock, showed distinct marks ofthe Leghorn comb to the sixth, and slight indication in seventh DURATION OF IMPREGNATION. 27 and eighth egg hatched after removal of the Leghorn cock. Iconclude from this that the average influence of a mes-alliancebetween birds of different breeds may be considered as commen-cing with the third, and terminating with the seventh or A Non-Freezing Water Fount. CHAPTER of the Eggs. Properly, this should commence with the laying of the eggs?and I will start from as near that point as possible. Many beginners in the poultry fancy seem to think that eggs in-tended for sitting need a particular kind of treatment and manipu-lation. While there is no doubt that careful handling and protec-tion frequently greatly add to a successful result, still it by nomeans follows that eggs will not hatch if subjected to rough treat-ment and exposure to cold. So far as the latter is concerned, I would much rather the eggsbe kept in a room where the temperature ranged from freezingpoint to forty degrees Fah., than in a place where the heat reachedas high a point as eighty degrees. Of the two extremes, I wouldalso prefer to trust the eggs to the lower; by which I mean, that Iam convinced that any ordinary degree of cold—say ten degreesbelow the freezing point—does not necessarily ki
