perature for the several sections, which is a strong point 
where chicks of different ages are kept in the same house. 
The colony brooder house is convenient for the poul- 
tryman who breeds ona smaller scale and who would 
not be justified in building a large house. With the ad- 
vent of the separate heating systems plans were brought 
out by which brooder houses could be made very cheaply. 
A very good house of this kind has been made by simply 
laying a piano box flat on the ground, the widest side 
down, cutting necessary doors and windows in it and at- 
taching one of the heating systems. <A brooder house uf 
this kind may be made of any large packing case with 
but little trouble. 
With every brooder house equipment whatever the

plant adopted. 
BROODER HOUSE.—A good type of brooder house 
built a few years ago for the Storrs Experiment Station 
in Connecticut, by Prof. F. H. Stoneburn, and described 
by him is shown on pages 90 and 91. This was built for 
individual brooders and has been found very’ successful. 
It is easy to build, cheap and perfectly adapted to be 
operated conveniently. The house as described was built 
on a slope, but we have seen one which was built on per- 
fectly level ground, the alley being excavated and drained, 
but instead of a stone wall in the alley it was lined with 
concrete, which was water-proofed in the ordinary way 
with cement mortar. We have seen several brooder 
houses built on this plan, or a simple modification of it, 
which seemed to be everything that could be wished in 
a building of this kind. The slope on which this house 
was built sloped with an eastern exposure. A better ex-
