WHY YOU SHOULD USE PETALUMA ELECTRIC INCUBATORS 
The regulation of Petaluma Electrics is positive and 
accurate. The temperature never varies. 
Pure, warm, fresh vitalized air surrounds the eggs at 
all times, making healthier and stronger chicks. 
They are the simplest machines in the world to run. 
There is only one adjustment. No lamps to fill, clean or 
trim. Labor reduced to the minimum. All the old 
drudgery is done away with by these wonderful machines. 
They can be attached to any ordinary electric light 
socket, can be run in any room in the house—no muss 
or odors. 
They are the finished product of nearly thirty 
years of careful experimenting and tests. You get the 
most wonderful hatches the poultry world has ever 
known. 
Many of the largest and best hatcheries in the world 
have adopted our machines; also we have converted the 
machines they have been using into electric incubators, 
enabling them to hatch bigger, better and stronger chicks 
than they have ever been able to do previously. Early 
in the season of 1919-19 20, they converted in a few 
weeks sufficient machines in the big hatcheries of Peta¬ 
luma and elsewhere, to equal 1500 504-egg machines, 
and that good work has been going ever since. This 
would not have been possible, except that the hatchery- 
man recognized that nothing in the world equaled Peta¬ 
luma Electrics. If these men of long years of experience 
in hatching are adopting ours it ought to be safe for you. 
No hatcheryman will spend several thousand dollars in 
making the change unless he is satisfied he is getting 
something superior to anything he has previously had.

Petaluma Hot Water Incubators 
Combine every feature of mechanical supremacy and 
enduring qualities and are in every respect just what is 
claimed, the best hot water incubators at the lowest price. 
The water is circulated in copper tubes of larger size 
than is usually put into incubators, therefore more radi¬ 
ating surface and hence better heating. The entire heat¬ 
ing system being copper, there will be no rusting or accu¬ 
mulation of rust or scale in the pipes to obstruct the 
circulation of the water. 
ELECTRICALLY HEATED HOT WATER 
INCUBATORS 
Where one has the electric current service, it is better 
to use our regular electric incubators. One derives all 
the advantages of the character of warmth supplied 
through our electric system, which many operators claim 
has a very subtle and invigorating influence upon the 
development of the chicks. Should anyone, nowever, de¬ 
sire to heat the water by electricity instead of coal oil, we 
can furnish an adapter heating element, to insert in the 
heater, and a thermostat and breaker and necessary con¬ 
necting wire at a very liberal price. 
Lamp and Burner 
Our Petaluma lamp with sleeve burner is used, making 
it more economical in consumption of oil than any other 
machine. The tank style of fount is used on two larger 
size incubators, which carries enough oil for a week or 
more, thus lessening the labor in caring for the machines. 
Moisture Pan 
The moisture pan is placed in a most unique position. 
It is inserted through the front of the machine, is easily 
handled, and the operator can always see exactly the 
amount of water it contains and very readily put in more 
when it is needed.
