248 CHEMICAL FERTILIZERS 



caustic soda with 100 Ibs. of sulphur and 100 galls, of 

 water. 



Chlorine. In the form of chloride of lime or bleaching 

 powder, chlorine finds its way into use on the farm. For 

 washing cow-byres, latrines, etc., it is very useful. Bleach 

 is fully described in the volume on " The Alkali Industry " 

 by Partington.
