Dubois lengthens the cords which suspend thebaskets, so as to bring them nearer the floor of thechamber, where it is not so hot. He also moves theeggs daily so as to regulate their heat. It is not saidwhether this method has been much tried. 32S INCUBATION. Instead of the dry heat of a stove or oven, M. Co-pineau makes use of hot water carried in a pipe alongthe floor of a chamber constructed for hatching. Healso has pipes or flues for the purpose of ventilationand regulating the heat; while he places vessels ofwater in the chamber to render the air equally moistwith that under a sitting hen. Fig. 66. The incubation of chickens by hot water is said tobe the invention of M. Bonnemain of Paris. Theabove is a section of his apparatus, consisting of aboiler (a); a box or building (b) for hatching eggs; acage or coop (c) for rearing the chickens; tubes (d)for circulating the hot water ; a supply tube (h) andfunnel (e), and safety tube (/).
