 PRAIRIESTATE INCUBATORS TOR 1908. 



To get a high per cent, of "liv- 

 ablf" chicks is where the value 

 comes in the Prairie State. Some 

 incubators may bring out nearly 

 as many chicks, but wait ten days 

 or tv.-o weeks and tlien count 

 your chicks. That's the test. It's 

 tlie number of chicks that live 

 that tells the story of efficiency, 

 owing- to the fact that it hatclies 

 as near like the old hen as human 

 ingenuity can copy nature. Every 

 chick liatched in a Prairie State 

 Sand Tray Incubator is bubbling 

 over with vitality the minute it 

 pops out of the shell and you can 

 rest as.sured it will thrive and 

 grow rapidly. 



All Prairie State Incubators are 

 of the hot-air type, insuring long 

 life and durability; no tanks to 

 rust out or spring a leak in the 

 middle of the hatch. Tlie outside 

 case.'etc, Is nicely finislied in nat- 

 ural wood, unstained. The space 

 between the inner and outer case 

 is insulated with 2'i inches of 

 cotton batting, 3 inclies on top. 

 •The heating system is a combina- 

 tion of radiant heat on the top of

 tem of ventilation. In this "re- „ „ ,

Did you ever notice the hen that steals her nest on the 

 ground? That's natural incubation. And she usually 

 hatches every egg. don't she? We've copied her. We use 

 a wet sand tray, covering the entire bottom of the machine 

 in close proximity to the eggs, thus furnishing the proper

It may be attached to any form of outdoor brooder two feet or more in height, 

 to any size or form of colony house, shed, coop, piano, dry goods or organ box. It 

 also enables those who wish to liulld their own brooders to get the best brooding 

 device possible in an economical manner. It fills tliat want, felt by everyone who 

 raises poultry, for something they can use anywhere, any time, and do the work 

 well. 



The hover is twenty-two inches in diameter, the top of which is wood, lined 

 with strawboard, a 4-lncli rim extending downward, to which is attached six 

 inches of felt curtains. The hover stands on three iron feet, but Is not stationary, 

 and may be raised and moved instantly, if desired. 



A thermometer is provided, which may be read from the outside without dis- 

 turbing any part of the brooder. The lamp used is made of metal, using a No. 2 

 Sun Hinge Burner and a metallic chimney seven inches in length, thus assuring a 

 steady, bright, clear flame; the lamp being on the outside of the brooder in view 

 at all times. Surrounding the hot-air flue or cliimney is a fresh-air pipe through 

 which fresh air, slightly warmed, is injected into the upper part of the brooder. 

 This diffuses downward and through the curtains, thus furnishing a perfect system 

 of ventilation. At an additional cost of $1 to the regular price a standard wafer 

 regulator may be attached to the hover, by the use of which a uniform temperature 

 can be maintained without close attention. It is not essential, but a great con- 

 venience during the cold, changeable weather, and greatly aids the operator in 

 supplying the desired conditions for newly hatched, chicks, relieving him of any 

 cause of worry concerning the brood.
