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 
considerng 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.

GEA TLEMEN:—Yours of the 16th received, and we are glad to let you know what results we have had 
with the incubators that we purchased of you. Previous to the time that we purchased these machines , we had 
four 360 egg machines oj a no-moisture style and run them for six seasons , and sold them Jor almost nothing as we 
could not raise one half of the chicks hatched from them , and those we did raise were practically "worthless. From 
these results we decided to hatch by old hens , and did so for two seasons and got good results. 
The spring of 1908 we purchased of you a 240 egg machine which we have run three seasons and have raised 
not less than 83 per cent.of all chicks from it and the 390 machine purchased this season; we have hatched 900 
with two machines and 300 with hens this season and the chicks from the machines have lived as well and grow 
faster then those with hens because one thing they are free from lice; and then another reason, when they feel 
chilled they have the Universal Hover to run to which is ready at all times to hover them. 
This combination of machines cannot be beat for hatching and raising chickens. Aow that we have found 
a machine that will hatch chicks that live, we are going to raise broilers this winter and shall order three or four 
of the 390 egg machines this fall. If at any time we can speak a good word for the Prane State Incubators or 
Universal Hovers , we shall be more than pleased to do it because they are the best machines on the market today in 
our opinion. Yours truly,

The PRAIRIE STATE UNIVERSAL HOVER 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 cnimney is a fresh-air pipe, through which fresh air, slightly warmed, is injected into the upper 
part ot the brooder. This diffuses downward and through the curtains, thus furnishing a perfect system of ventilation.
