the tank 1 3 isfilled with water to the proper height, as is the pipe system 1 L extending thereform. Inasmuch; as the water pipe ll is inclined upward, it will be obvious that the upper end of the pipe, that is, theend which is entered into the incubator, and the" coilsiof pipe. disposed within the incubator will be only half-filled with water.

cubator. At the same time fresh air is drawn inthroughthe perforations 20 and into'the space 21 where it rises around the Wall'of thecasing 10 their around the tank,-

and around the pipe 14, and thus; passes intothe incubator, QThus all the fresh air entera. ingllth'e incubator is warmed prior to itsr entrance'lih The fumes from the lamp pass off througlfithepipe section 26, into the space 25' -and circulate around" the wall of the casing 15 and eventually pass-out through the bottoinof. the heater between the walls'l'e andza It will be' seen that no heat is wasted in this heater an drfurtherthat the airjwhich generally 3% I do notiwish to be limited,

and operate in connection with an incubatoror brooder than it i s to operate aheater using hotair alone for the heating agency.

The advantages of using a hot water heat-'3 ing system'infplace of a hot air heating system is that should the fire go out in a hot air machine thetemperatureof the ini i 7 cubator or. brooder will drop instantaneously with disastrous results. With hot water as the heatingimedium, when the lamp goes out, thajtris,- if it sliould go out, it willrequire hours "for the machine to; becomev chilled sufliciently' to endanger the eggsin theincub'ator, Ihave found in practice that it is onlyfnecessary' to fill the ,tank 13 7 once for a hatch. Afurther advantage of this heater is that the air used'for ventila-,

tionis heated before it enters the incubator. This warm fresh air is carried into the top of the lncubator by the naturalcurrent set then: the heatedfresh, air works its way down through the incubator into the egg The lamp is then heated, Which heats the water injthe tank and in the pipe system leadingh; therefromand into the incubator, This hot water ci'rculates through the coil'in thein- 1 and nursery, taking ofi' the 6111" air with *it as it passes off at the outlet ducts usually found in ea'chcorner of incubators.

a casing surrounding the fresh air chamber but spaced therefrom and closed at its top Y but open at its bottom, said casing having parallel extensions or parallel walls extending on each side of and in proximity to the.

side of the air conduit, thespace inclosed by said walls being closed at the top and openat the bottom, a pipe leading from the interior of the lamp chamber into 'the lower portion of said extended part of the outer casing, a filling pipe extending from the tank upward through both of said casings, a cap detachably closing the filling pipe, a tap extending "from the tank outward through both'of said casings, and a vent pipe connected to the Water pipe and extending upward through the outer casing.

4.
