fast as formed. A better way is to support the cal- 

 cium on a screen of galvanized wire, with a galvanized 

 pan below for catching- the brine. This allows of a 

 free circulation of air around the calcium. This 

 apparatus should be suspended near the ceiling of the 

 room, one end slightly higher, to allow the brine to 

 run off into a galvanized iron pail, supported at the low 

 end of the pan. Galvanized iron is specified because 

 black iron rusts badly when exposed to the air. 



^ st ^ better way of applying chloride of calcium, 

 ~ wn i n makes the calcium do two separate and distinct 

 duties, is a method recently designed by the writer. 

 It has proven itself especially valuable for use in 

 rooms where the air is circulated by mechanical 

 means, and in which the air is cooled by passing over 

 brine pipes, through which the brine is circulating at 

 a comparatively high temperature. If low brine tem- 

 peratures are used in combination with the device 

 about to be described, the tendency may be to dry the 

 air to such an extent as to be detrimental, and ample 

 pipe surface must be provided and the quantity of 

 brine flowing through pipes reduced so that no ex- 

 cessive drying effect will take place. The device 

 consists simply of supporting a quantity of chloride 

 of calcium above the cooling coils, so that the brine, 

 resulting from the absorption of moisture by the cal- 

 cium, will trickle down over the pipes. This effect- 

 ually prevents any formation of frost on the pipes, 

 and therefore keeps them at their maximum efficiency 

 at all times. The air, in passing over the brine 

 moistened surface of the coils is purified, and as the 

 brine, after falling to the floor of the coil room, goes 

 to the sewer, no contamination can take place. 



Do not in any method of using chloride of calcium 

 evaporate the water from the brine and use the salt 

 over again. The impurities will stay in the salt 

 to a large extent, which is quite harmful, and the 

 calcium has at least lost its value as a purifier, to a
