vigorous chickens which are easy to rear.

A Twentieth Century Wonder. 
50-Egg Incubator Complete, 
ready for operation.

during hatch. 
Holds 50 Eggs. Constructed entirely 
of metal except insulation; self reg¬ 
ulating ; requires no supplied moist¬ 
ure; will last a life time. 
Complete directions with each 
machine. 
The supply of heat in the “ Model ” Improved Cycle Hatcher comes from the 
centre and is radiated in all directions, carrying with it an abundant supply of fresh 
heated air, which is required to travel only six inches to reach every egg in the nest. 
The heat is governed by a three-inch wafer regulator which is placed so close to the 
eggs that it is sensitive to the natural heat of the growing embryo in the egg as 
well as the heat from the lamp. 
One grand feature of the “ Model ” Improved Cycle Hatcher is, there is no 
lifting of the top of the machine to see the thermometer. By a simple device used 
the operator can see through a glass window without touching it, also any stage of 
the hatching can be watched from the pipping to the tumbling out of the shell, a very 
interesting study.
