it Is Important That There Be Plenty
 of Fresh Air But Not Drafts.

- .a Any cellar or room in which incu-
 bators are to be operated should be arranged so that the eggs will be pro-
 vided with plenty of fresh air
 throughout the entire hatch. Incu-
 bators are operated in great variety of places with success and where there are a few small machines they may be run in any well-ventilated room or house cellar. A special cellar or incubator house should beprovided tensive and such room should be constructed to provide a maximum of fresh air with a minimum of draft.
 The most essential thing in incubation is to have a room which is not sub ject to great variations in temperature
 and In which the air is always fresh. Although chickens will hatch well
 with a certain percentage of carbon dloxide in the egg chamber if there are greater than 150 parts of carbon
 dioxide in 10000, experiments indicate
 that the hatch is affected in @ marked degree both in the decrease in chick
 ems matched and in their vitality. It is practically impossible to remove this
 gas from the egg chamber without
 serious results from excessive evapo-
 ration so that the importance of a
 sufficient amount of ventilation to pro
 vide good oxygen at all times to. pass
 through the incubator is very appar- ent.
 If the incubator room is built above
 the ground the walls should be double
 and the entire building well insulated. Good results in matching are frequent ly obtained in incubator rooms en- tirely above ground, out cellars which are one-half or more in the ground
 are more likely to give satisfactory re-
 suits because of the greater ease with
 and because of the lesser evaporation
 below the surface of the ground. The incubator room should be large enough
 to allow the. attendant to work around
 the machines conveniently.
 The accidental hitting of a .thermo-
 stat or regulator has more than once caused the ruin of good hatch. There
 are systems of ventilation advocated for incubator cellar, any of which are satisfactory so long as they do not create direct draft vn any of the
 machines. There seems to be nothing
 better for taking care of the air in in-
 cubator rooms than windows covered
 with. cloth curtains. This material
 being such that it will permit a grad
 ual current of air to pass through all
 of the time. This provides good ven-
 tilation without drafts and at the same time prevents the sun from shin-
 ing on the machines. There should
 be at least two Of these windows and
 where there are more than three ma
 chimes four because the kerosene
 lamps used for providing heat burn
 up great deal of oxygen and give
 off a considerable amount of carbon. It is we'll to have an incubator cell lar with concrete floor because 1t
 can be kept more sanitary and is easi-
 CT to clean.
 When incubators are run in house cellars or in a room which is covered
 by insurance, poultrymen should be sure to obtain a permit from their in- l surance companies before starting | their machines. Many of the best in- cubators have heating appliances which are approved by the. national l association of underwriters and for a very few cents per month permit can be obtained to run these machines in buildings covered by insurance. Any | man who runs an incubator in an in- sured building without a permit can
 not obtain anything from his company | in case of fire and the risk is not
