and cover it over with lumber and dirt or 
logs and dirt, and you will have one of the 
very best incubator-rooms; or, if you live 
in a country where stone is plentiful, you 
can build a good incubator-room out of 
stone and mud; of course, if you have the 
capital, it is better to build something nice 
that will be an ornament to your place, 
and then, after the hatching season is 
over, it can be used for something else. 
There should be no artificial heat in 
an incubator room, for the temperature 
varies in such a room so much that it is 
hard to keep the temperature in the incu- 
bator right; and then, too, the artificial 
heat dries out the air in a room so much 
that the air in the incubator is liable to 
get too dry. I know that a good many 
chickens are hatched in rooms with arti- 
ficial heat, but it is not a good place to 
hatch them; that is why I advocate a 
cellar or dugout or other well-built and 
well-insulated room.
