To get a high per cent, of "liv- 

 able" chicks is where the value 

 comes in the Prairie State. Some 

 incubators may bring out nearly 

 as many chicks, but wait ten days 

 or two weeks and tlien count your 

 chicks. Tliat's the test. It's the 

 number of chicks tliat live tliat 

 tells the story of efficiency, owing 

 to the fact that it liatches as near 

 like the old lien as liuman ingenu- 

 ity can copy nature. Every chick 

 hatched in a Prairie State Sand 

 Tray Incubator is bubbling over 

 with vitality tlie minute it pops 

 out of tlie sliell, and you can rest 

 assured it will thrive and grow 

 rapidl3^ 



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. The oi^tside 

 case, etc., is nicely finished in nat- 

 ural wood, unstained. The space 

 between the inner and outer case 

 is insulated with 2^4 inches of 

 cotton batting, 3 inciies on top. 

 The heating system is a combina- 

 tion of radiant heat on the top of 

 machine with the diffusive sys- 

 tem of ventilation. In this re- 

 spect our machine differs from No. — 100 hen eggs; 135 lbs. crated 

 all others upon the market. No No. 1 — 150 hen eggs; 160 lbs. crated 

 diffusion screens, with their faulty No. 2 — 240 hen eggs; 240 lbs. crated 

 distribution, are used. No. 3 — 390 hen eggs; 275. lbs. crated

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 maciiine in close proxi- 



Prices include all attachments, such as e 



mity to the eggs, thus furnishing the proper amount of 

 moisture and reducing the evaporation from tlie eggs to the 

 same per cent. (9 to 11 per cent.) as under a hen. This insure.s. 

 chicks full of vitality — cliicks that live — just like hen-hatched.

Universal Hover. 



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 build their own brooders to get the best brooding" 

 device possible in an economical manner. It fills that 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-inch rim extending downward, to which is attached six inches ol: 

 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 disturb- 

 ing any part of th-e 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 chimney is a fresh-air pipe through which 

 fresh air, slightly warmed, is injected into the upper part of the brooder. This dif- 

 fuses downward and through the curtains, thus furnishing a perfect system of 

 ventilation. At an additional cost of $1 to the regular price a standard water regu- 

 lator 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 convenience 

 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.
