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 Avhere 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-

If impure w^ater 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 allow^ed 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 nojse caused by the vibrations of the electric fan in 
contact Avith 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
