The bottom of the pens should consist of sand which, when it becomes wet, and before it becomes offensive, should be covered with fine sawdust. This is a good absorbent and disinfectant as well. The inside of the four brooders next the heater should be filled up with hay chaff to within four inches of the pipes, the distance being gradually increased as you near the other end of the building, until the whole eight inches in height will be required, using simply sawdust enough to disinfect the bottom of brooder. This is my present brooding arrangement, with the exception of a common door handle screwed on each brooder cover to facilitate handling. It may not suit every one; some may want it more ornamental, more expensive; others may wish to simplify it still more. But such as it is, it is now all ready for use, with heat applied. But those little ducklings, who have been waiting all this time in the machine, are getting both hungry and impatient, and require immediate attention. The food which has already been prepared consists of a formula composed of four parts wheat-bran, one part corn-meal with enough of low grade flour to connect the mass without making it sticky or pasty, in fact, it should be crumbly so that the little birds can eat it readily. About five per cent. of fine, sharp grit should be mixed into their first feed, after that, one or two per cent. is all sufficient. This grit should be increased in size as the birds grow older. About the third day, a little fine beef-scrap should be introduced, soaking it a little before mixing. When a few days old, a little green rye, if obtainable, should be given them, or as a substitute, finely chopped cabbage or lettuce. When the birds are two weeks old, one part corn-meal to three parts bran should be used. This food should be scattered upon the feeding-troughs, which are simply one-half inch boards, nine or ten inches wide, by three or four feet long, with laths nailed on the sides and ends. Small water-cans, inverted in tin saucers, so that the ducklings can drink readily without getting wet, should stand convenient to the food. How to Remove the Ducklings Without Injury. To facilitate the removal of ducklings from the machine, I have a square basket some two and one-half feet long, by fifteen inches wide and one foot high, with close covers, hinged in the centre. In order to secure the ducklings, usually all that is necessary is to open one door of machine, hold this basket under it and make a little chuckling noise, and strange to say, the little fellows will run out over the pipes, over the glass door, down into the basket in dozens as fast as their little legs and wings can carry them. This basket will hold 100 ducklings conveniently. When full, it should be carried to the brooding-house and carefully inverted over the feeding-boards.
