Theinlet pipe is at the right hand top corner, and the only outlet is atthe bottom. In the centre of the front is a pipe to supply air, but 10? cashmores incubator. the latter is always warmed, before being admitted into the Incu-bator, by having a considerable length of pipe running alongsideof the cistern. The air has no direct contact, either, with theeggs, inasmuch as the pipe rises nine inches inside, and a currentis secured at the top by the aid of a very small piece of piping,through which it is supposed the steam from the hot water escapes,and so dampens the eggs sufficiently. The cistern holds twenty gallons of water. The nest is preparedby placing an inch of sand in the bottom, which is kept damp,over which is put straw or fine hay on which to lay the eggs .. Fig. 80.—cashmores incubator. The same remarks apply to this as to the two previously men-tioned. It requires some experience and also knack in deter-mining just how much boiling water is daily necessary to keep upthe temperature, and especially in variable weather. cashmores incubator, illustrated at Fig. 80, is the last of the foreign inventions we shallnotice. The machine is two feet square and one and a half high. Theegg drawer is shown in front, partly open; the bottom of thisdrawer is of perforated zinc or wire cloth, over which is laid apiece of flannel or felting, on which the eggs are placed.
