I disinfect my duck yards with rye about Sept. 1. When, in this climate, frost has destroyed all green vegetable life, then rye is in its prime. If sowed September 1, in duck yards, it will attain a height of eighteen inches, and if sowed thickly will crop many tons to the acre. When corn-fodder is gone, we use green clover, then turnip, cabbage and green rye in turn and then just before a snow storm we cut a large quantity of the frozen rye and pile it up in the shade, where, of course, it will neither heat or thaw. Should we get out before the snow is gone, we always have surplus of clover-rowen cured for the purpose. This, together with refuse cabbage and boiled turnips, small potatoes, etc., makes a fine winter diet on which breeding ducks will always thrive if the other ingredients are properly mixed,--a diet upon which, combined with housing and plenty of exercise, the birds are bound to contribute a good quota of strong fertile eggs. I mention this particularly here, because the mortality among young birds will depend largely upon the strength and vitality of the eggs from which they come. Natural Duck-Culture. Doubtless some of my readers are getting impatient and saying to themselves, "Why do you not give us some ideas how to do this business in the natural way? Many of us wish to begin small. Every one has not the conveniences to use or the means to command incubators." I am coming to that. I have a vivid recollection of using hens to incubate with some twenty years ago; and the persistent obstinacy of the perverse birds, the large proportion of valuable eggs spoiled and broken, as well as the time consumed in caring for them, are still fresh in my memory. It was wholesome discipline for me. It will be the same to the reader, and enable him to appreciate a good incubator later on. A good, quiet hen, who attends closely to her business, will always hatch as large a proportion of her eggs as a good incubator; but there are so many with dispositions quite the opposite of this that it leaves the odds largely in favor of the machine. Success with hens depends quite as much with the operator as with machines. He must begin right and hold out to the end. As ducks seldom make good incubators, he will have to rely upon hens to do that business for him. The best breeds for that purpose I have found to be the Brahma or Plymouth Rock. A cross of these birds makes a good quiet sitter.
