I have seen their machines drop one de-gree of heat by simply opening the door and letting ina draft of air for an instant; the fact is they fluctuatewith the weather, and their makers say they must beplaced in a room that will not get cooler than 50°, andthat the temperature of the room must not vary morethan ten to fifteen degrees. Besides they are notdurable, they will rust out in two years and becomevalueless. The lower chamber of our Hatcher can be used as anursery for a few days if desired. I have kept chicksthere for six PERFECT BROODER. Our Brooder is as perfect as our Hatcher, and theonly one that can be used to advantage on a largescale. It is the only one that imitates the hen inbrooding her chicks, viz., the chick presses its back 26 Artificial Incubation. close against the hens body and is comforted by thewarmth. In onr Brooder, the chick presses its backclose up against warm water pipes and is just as com-fortable as when under the hen. In other brooders atank is used and is placed eight or ten inches abovethe chicks; the chicks cannot come in contact with theheat which they crave doing; they consequently huddletogether and on top of each other, and the result is, theweaker ones are always crushed, and you will findthem dead every morning regularly until more thanhalf the chicks are gone. In our Brooder we use 1 1-4inch gas pipe covered with tarred paper a
