ness as fast as it accumulates, it is possible to do something 

 towards keeping the inside of the building dry and free from 

 mould. 



To give anywhere near satisfactory results, the ventila- 

 tors should draw from near the floor in winter, and from near 

 the ceiling in the summer. By drawing off the cold air near the 

 floor in winter, the warm air is forced down, or rather the air 

 is made to circulate by removing the lower layers. If it is pos- 

 sible to admit warm and dry air near the ceiling in the churn 

 room it will greatly assist in keeping the room free from damp- 

 ness in the winter. Warm air may be drawn from the boiler 

 room by having a hole near the ceiling in the wall between the 

 work room and boiler room, and a fan run from the shaft can be 

 used if convenient. This would help materially in getting the 

 air to circulate. 



When the smokestack is of sufficient size, it may be used 

 for ventilating the creamery with very good results. If one side 

 of it faces into the churn room, there should be two registers 

 placed in it when it is built ; one about six inches from the floor 

 and the other near the ceiling. These registers should be from 

 six to ten inches square. If the room is large it would be best 

 to have one flue at the opposite side of the room from the 

 smokestack; such a flue can be extended through the ceiling and 

 connected with the smokestack upstairs. Where the smokestack 

 is located away from the churn room it may be connected with 

 the ventilating flues by running a pipe from the flues into the 

 smokestack where it is most convenient. 



All .flues should have registers within six inches of the floor 

 and also near the ceiling, and these registers should be con- 

 structed so they can be opened or closed at any time. The reg- 

 isters near the floor should be used for ventilating in cold weath- 

 er, while those near the ceiling should be used in hot weather. 

 The smokestack should be built large enough to allow for ven- 

 tilating through it, otherwise the draft to the boiler would suf- 

 fer. The registers used for ventilating should be regulated from 

 time to time; for instance, at times when the most draft is 

 needed for the boiler, the registers may be kept closed, or nearly
