STATE INCUBATORS 



Have Many EXCLUSIVE PATENTED FEATURES 



For this new season we will offer a full line of incubators meeting every existing condition, all embodying the well- 

 known Prairie State principle, all equipped with the sand-tray method of supplying humidity, and with the Prairie State 



Patented Eddy-cur- 

 rent Heat Distrib- 

 utor, giving uni- 

 form heat distri- 

 bution even in a 

 two - thousand - egg 

 machine — a feat 

 never before ac- 

 complished with- 

 out tray-raising or 

 lowering devices. 



Prairie State In- 

 cubators contain 

 many exclusive 

 patented features 

 found in no other 

 machine. The Sand 

 Tray models have 

 the best reputation 

 ever made by any 

 i incubator for high 

 hatching results — 

 for large chicks of 

 extreme hardiness. 

 Remember, your 

 profit comes from 

 the "Chicks That 

 Live." 



KEYSTONE INCUBATOR 



is small, compact, efficient, moderate in price. Designed for 

 fanciers, for beginners, or for those who wish to hatch only 

 a few chicks each year. Given to the trade only last season, 

 somewhat as an experiment, it instantly made a record for 

 high hatching efficiency, which has prompted us to offer it 

 again in a perfected condition, with every weak point removed. 

 Price, $12.00. 



The Prairie State Sand Tray Incubator 



■offered now in a further im- 

 proved condition, fitted with 

 our latest-type fool-proof heater, and provided with a wire chick 

 tray substituted for the burlap formerly used, which, resting 

 just above the sand tray, permits this tray to remain through- 

 out the hatch, thereby retaining uniform humidity until com- 

 pletion. Series A. Price 



No. 1 — 150 hen eggs; 160 lbs. crated $22.50 



No. 2 — 240 hen eggs; 240 lbs. crated 32.00 



No. 3 — 390 hen eggs; 275 lbs. crated 38.00 



without nursery — a new model this year — 

 designed to meet a new and increasing de- 

 mand for a machine of this type. It is pro- 

 vided with a new and exclusive device, by 

 means of which the chicks may be hardened 

 upon the hatching tray. The machine is 

 built in 200, 300 and 400-egg sizes, and is 

 regularly fitted with egg-turning trays, 90- 

 egg capacity, which overcomes the objection which 

 is sometimes made against handling heavy trays in 

 the other large machines. The thermostat is hung 

 upon the egg level, which enables the incubator to 

 regulate the temperature more closely under wide 

 variations than any incubator ever built. Prom the 

 fact that egg-turning trays are used, and a Begulator that very seldom needs 

 adjusting, cuts down the time of operation to the lowest possible amount.
