Four drawers or trays (one at the left hand out of position)eighteen inches by ten inches, each perforated with a number ofsmall holes half an inch from the bottom for the exit of the foulair engendered in the tray during incubation, and another row ofholes near the top for the inlet of fresh air, thus causing a contin-uous change in the air of the drawers for the successful oxygena-tion of the blood. Underneath a perforated zinc bottom in each. HBaagaBagaPBagaasaBggsasjsg—BssaanggEag—nam—h^ Fig. 78. drawer is placed a layer of finely sifted garden soil, to the depthof about half an inch, to be constantly kept damp (not wet), andwhich diffuses a genial moisture to the air and eggs during thewhole period of incubation. Each drawer is capable of holdingbetween forty and fifty eggs of the smaller breeds of poultry, orabout forty duck eggs; thus this Incubator can contain at onetime from one hundred and fifty to two hundred eggs, and canhatch any size of eggs from a swans to a sparrows. 7. Four pipes to convey the warm water from the cistern aboveto the Artificial Mother below, which is seen in Figs. 76 and 78,No. 10. 8. Nursery for chickens, the front containing glass, and theback wire netting or wood (No. 9, Fig. 76). When more room isrequired for chickens, an extension equivalent to half the lengthof the Incubator can be attached to each end, thus doubling thearea of the run. 10
