12 CHICKS

 Some think it too expensive to build a house for one or two 

 machines, not knowing that a good one can be built at a 

 low cost. It is the object of this article to describe such 

 a house, one that is not only cheap to construct, but which 

 has the essential features. 



I have designed this house in a simple manner and have 

 tried to make the drawings so that anyone not skilled in 

 the use of carpenter's tools may build it themselves. The- 

 tools required are a spade, pick, hammer, saw, square, 

 and level; tools that are found in almost every place. 



Essentials of a Good Incubator House. 



Having decided to build an incubator house, it is not a 

 problem of how to conveniently cover a hole in the ground, 

 but one of how best to build this covering that it may 

 fully perform its functions. To successfulh- accomplish 

 this, one must have knowledge of the requirements of such 

 a house. The following are a few of the essentials and if 

 your house will' not fulfill all of them as near as practicable, 

 when finished, it is useless to go to the expense of con- 

 structing it; the house cellar will do as well and will cost 

 you nothing as it is already built: 



First. The temperature within should remain nearly 

 stationary at all times, regardless of external changes. 



Second. It should have a system of ventilation that 

 ventilates without causing a direct draft on the machines. 

 Ventilation is the life of incubation; without the life giving 

 oxygenvit is impossible to develop the emb'rj-o cliick. 



Third. There should be plenty of sunlight in the house. 

 This will keep it sweet and clean and free from moldy 

 growths. Direct sunlight, if allowed to enter all day, 

 will heat up the interior, but this may be overcome by tack- 

 ing muslin curtains in front of the windows and having them 

 arranged so that they may be slipped back when desired. 



Fourth. It should be built on a high spot so that it 

 will be dry the year around. 



Fifth. The temperature within should be about fifty to 

 sixty-five degrees, then eggs for hatching may be stored in 

 places not occupied by incubators. If this house is well
