A HUMIDIFTER FOR I.EMON CURING ROOMS.

the curing rooms, in order to handle the .humidifier and the ventila- 

 tion of the curing rooms intelligently. 



For rooms of the kind and size and under the conditions described 

 in this paper one humidifier will generally be sufficient for use in five 

 rooms. With better insulation for the rooms fewer "humidifiers will 

 be needed, and where the insulation is not so good or where temper- 

 ature fluctuations are greater than those where these rooms are 

 located, more humidifiers will be needed. The cost of the humidifier 

 need not exceed $25, in addition to the electric fan. The cost of 

 operation will depend on the cost of running the fan. The deprecia- 

 tion in the value of the appara- 

 tus is insignificant.

If impure water is used in the humidifier it will be found necessary 

 to wash the absorptive cloths occasionally. When the humidifiers are 

 not in use the cloths should be allowed to dry out thoroughly. 



OTHER USES OF THE HUMIDIFIER. 



The successful use of the humidifier described in this paper in 

 improving the humidity of private homes and other living rooms 

 has been demonstrated. In this case, much smaller humidifiers can 

 be used. The noise caused by the vibrations of the electric fan in 

 contact with the humidifier hood can be largely eliminated by 

 inserting a strip of rubber at this point. 



The use of the humidifier in dry or desert sections, in restaurants, 

 offices, and living rooms not only increases the humidity in these 

 rooms but also lowers their temperature, both of which conditions
