The San Jose Scale is very largely responsible for the present enthusiastic 

 crnsade against the old neglected, moss-covered orchards. Everyone is pruning 

 and spraying. Why? To destroy the San .Jose Scale. Yet I find that a very 

 small percentage of our farmers know what this dreaded thing is which they 

 are so earnestly endeavouring to destroy. If any other spray than the lime, 

 sulphur and salt were being used, a reaction against all spraying would cer- 

 tainly follow the poor results of so much misdirected energy. By using the 

 lime, suliJhur. salt spray beneticial results are almost certain to follow, whether 

 the scale be [iresent or not. Nevertheless, everyone who grows trees or shrubs 

 should learn to know this destructive little pest and be prepared to combat 

 it, since it m,-iy at any time ajipear upon the ornamentals of the city lot as 

 well as the trees of the dd home orchard. Dr. L. O. Howard records it upon
