GENUINE PRAIRIE STATE INCUBATORS AND BROODERS. 
To those who desire to rear as well as to hatch chicks and ducks, 
the selection of an incubator is of vital importance. The high death- 
rate experienced with chicks the first ten days is more frequently due 
to imperfect incubation than to any other cause. Too many incubators 
of to-day are constructed with reference solely to hatching the desired 
numbers without considering the manner in which they are brought 
into existence. 
Weak, anaemic chicks, lacking in strength and vitality, are of no 
value, if you hatch thousands; hence the importance of carefully 
considering the merits of an incubator in this direction before making 
a selection. 
The Prairie State Sand Tray Incubators have proven themselves 
by thousands of tests, both in the hands of the novice, as well as in 
comparative results obtained by the large poultry plants using differ¬ 
ent makes of incubators. 
The perfect construction and automatic heat regulation of these 
machines makes them easily operated and results doubly certain.

Prairie State Incubator Co.: Bellingham, Mass., Nov. 8, 1907. 
Prairie State Incubators have always had a reputatio7i of being equal to any made, but in this 
new style you have certainly forged ahead. The large egg chamber appealed to my jtidgment as of 
great practical use, that wet sa?id tray took from my mind any anxiety as to proper moisture, a?id the 
close fitting egg tray allowed me to dry off my chicks zvithout dropping into the lozver part of the 
machine. That your Incubators hatch chicks of show quality is plain to me. as I have sold more Buff 
Wyandottes this fall that have won the blue ribbon than ever before. The chicks came out. of the 
machine big, fluffy and sprightly, and grew right along into shozv-room condition. I see nothing to 
improve in this 1907 incubator. Truly yours, N. IV. SANBORN, M. D. {Farm-Poultry Doctor). 
The PRAIRIE STATE UNIVERSAL PIOVER has completely 
revolutionized the rearing of chicks. No device ever offered to the 
poultry-raiser has received such endorsement. In cold weather and hot 
weather it has been an overwhelming success. As its name implies, our 
Universal Hover has a universal sphere of usefulness. There is practi¬ 
cally no limit to its adaptability. As an individual brooder, in brood 
houses alone or in combination with a hot-water pipe system, or may be 
used as an indoor brooder in almost any kind of building. 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 at¬ 
tached 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 disturbing 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 full 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 diffuses downward and through the curtains, thus furnishing a perfect system of ventilation.

THE UNIVERSITY OF MAINE, 
Prairie State Incubator CoHomer City, Pa. Orozio, Aug. 28, 1907. 
Gentlemen : Last Spring I bought fourteen Colony Brooders of you for use at Go- Well Farm. 
I have used them during the season and am more than pleased with them. I expect to build some 
more portable brooder houses — 7 12 ft. in size—next Spring, and shall get your Universal Hovers 
a7id attach one at each e 7 id of these double houses or brooders. I like them. 
Most truly, G. M. GO WELL.
