The Cornell book on artificial incubation and brooding . tems of heating and ventilating. Webster tells us that diffusion is an extensioti, dispersion, or circula-tion that spreads widely, or even 2inA proper spreading. Our systemamounts simply to a perfect method of ventilation, and unless yourincubator has this system it will never give the best results. Our advice is : Start vour machine with the outlet or ventilating slide partly open, say one-fourth. Then by using the egg tester everytwo or three evenings, and comparing the size of the air cell with thelines and dates on the drawings

Our advice is : Start vour machine with the outlet or ventilating slide partly open, say one-fourth. Then by using the egg tester everytwo or three evenings, and comparing the size of the air cell with thelines and dates on the drawings which show approximately the propersize of air cell in hen or duck eggs at various dates, during period ofincubation, you can tell whether you need more or less ventilation. Never put water in the moisture pans until \ou find the eggs needit. If you find the air cell is too small, in other words that the egg isnot drying away fast enough as compared with the following drawingsyou should open the ventilator wider. On the other hand if you find ducks egg. HENS EGG 1cornellbookonart00huff
