solutions of soaps to subdue it, and the more skillful, careful and 
resourceful growers were enabled to keep their orchards profitable, 
even though badly infested. During 1901 and 1902 experiments 
were made which demonstrated that the lime-sulphur-salt wash, 
long in use on the Pacific coast, was useful here also and it 
quickly came into general use. Within another two years it was 
clearly demonstrated that the salt was not of material value in the 
mixture. The mixture as now most widely used in this state 
consists of 20 pounds lime and 17 pounds sulphur, boiled an hour, 
to 50 gallons of water, the wash being sprayed on the trees while 
still hot or warm. This remedy not only holds the scale in prac- 
tical control, but also retards other insects to some extent, and is 
also claimed to be quite an effectual preventative of leaf-curl of 
peaches. Certainly it is efficacious in removing much moss, 
lichens and loose dead bark from trunk and branches and it seems 
to promote a healthy growth of new wood and bark. Indeed, so 
marked have been the benefits from this wash that many thought- 
ful, sensible fruit-growers declare that, all things considered, the 
appearance of the San Jose Scale in their orchards has worked 
to their ultimate advantage rather than otherwise. Certainly the 
appearance and spread of the pest has caused our fruit-growers to 
awaken to the importance of other insects also, as nothing else 
had done before, — and the science of Economic Entomology has 
gained a decided impetus from it.

Referring again to the present known conditions with regard to 
the San Jose Scale in this state, — it has been my frequent experi- 
ence to be asked by really intelligent and apparently otherwise 
well-informed men, whether this pest is actually known to occur 
within the borders of North Carolina. In order that at least 
every person here present may be assured in the affirmative on 
this point I present herewith a map of the state on which each 
locality where the scale is known to exist, no matter how 
slightly, is marked with a black dot. The numbers refer to the 
number of different premises actually known to be infested 
in the county. Localities which seem to be generally infested
