moved, and the house used as a growing or summer colony house, 
thus one house serves two purposes. These houses are easily 
built, with a four-foot wall at the back and a six-foot wall in front, 
with a shed roof, the front having a muslin curtain extending 
from the top halfway to the ground, on either side of a central door. 
The third type of colony brooder house is represented by 
the “‘ gasoline brooder house ’’* (Fig. 168), consisting of a portable 
A-shaped house with a very low side wall and eight by eight 
feet of floor space. The fuel used is gasoline. The house con- 
tains a large storage tank and a blue-flame gasoline burner which 
permits of continuous operation for from four days to a week 
without refilling the tank, this depending on the season. The 
hover is exceedingly large, and covered with a large hover board. 
This equipment will easily accommodate two hundred chicks. 
It is an exceptionally warm house, and can be used in extremely 
cold weather. It provides for an abundance of ventilation, and 
can be used in warm weather as well as cold. The cost is relatively 
low, the entire equipment, including all lumber, hardware, and 
metal, costing only about thirty-eight dollars. 
This type of brooder can be put to the following uses: (1) 
That of a brooder house for brooding young chicks when they 
are taken from the incubator. (2) The source of heat can be 
removed, and, the house being portable, it can be pulled out into 
a cornfield or orchard, and be used for a summer colony or devel- 
oping house. (3) When desired, it can be used for a small flock of 
laying hens during the winter, accommodating from ten to fif- 
teen birds. Thus it becomes possible to utilize the equipment 
throughout the entire year, and does away with the necessity 
of spending considerable money on a permanent long brooder 
house which would only be used for limited periods. Plans for the 
construction of this house are shown in figure 168 at A.
