wall should be double and the entire
building insulated. In sections that
have a mild climate, machines may
be operated in buildings with single
walls, but a well-insulated room is
always preferable.
Where only a few small machines
are used they generally run in a room
or cellar of the house Good results
In Matching may be secured in eel
lars as we'll as in rooms, and these
are more commonly used. Many or
these cellars are provided with some
system of ventilation beside windows,
muslin screens on the windows often
providing good ventilation without
draft. and keeping the sun from shin
ing on the machines. Cement floors
are easier to keep clean than dirt
floors. Where the equipment is ex-
tensive, special cellar or house
should be provided. " .-# =,
How to Operate a Machine, -
s In setting up the machine, get it
perfectly level. Do not plane of the
door if it sticks, until the machine
has been heated up and thoroughly
dried, Run the machine at about 5102
deg. Fahrenheit for day before put

touch the regulator for several: hours

to come back. to its regular temporal

second week, and 103 .deg-F Fahrenheit

Causes Of Poor .Hatehes. ,.., 3. 49,
The cause of poor matches is "a much
discussed question, which depends on
al great variety of circumstances. A
poor hatch Is more apt to be due to
the condition of the eggs previous to
Matching than to incubation, although
improper handling of either factor
will produce the same results. When
eggs fail to hatch, see whether the
breeding stock Is kept under eondi.

IS A daily temperature record should
abe kept of each machine The operat-
or can thus compare the temperature
ait which the machines have been
kept, which may prove valuable in
the future work, especially if the
brooder records can be checked back
against those of the incubator.
