is 40x20 feet, there being two pens each twenty 
feet square, which might be made the size of a 
smaller house. If this house were but ten feet 
deep, it would have to be eighty feet long to give 
the same number of square feet. A square house 
is more economical to build than a iong and narrow 
one, for it requires less material. The arrange- 
ment of the windows at the top of this house makes 
it light in Winter and helps to keep it cool in Sum- 
mer. A house that is only four feet high at the 
rear, where the fowls roost, is warmer at night 
than one which is higher, but this is a distinct dis- 
advantage in Summer, and poultry often suffer as 
much from a high as from a low temperature. 
Another way of lighting and ventilating deep 
houses and a somewhat cheaper one, is to have win- 
dows placed sky-light fashion in the front slope of 
a double-pitched house. The plan has sometimes 
been tried but reported a poor one because water 
came in around the windows. This trouble may 
easily be overcome by attaching zine strips to all 
sides of the windows, so that they will come outside

the snow from the windows, but as a rule the
