THE NATIONAL NURSERYMAN 
HOW INSPECTION LAWS ARE ENFORCED. 
In order also to obtain some data regarding the enforcement of 
the various Nursery Inspection Laws, Mr. Cole mailed, October last, 
to all state inspectors the following questions. Following each ques¬ 
tion are the replies received, tabulated and condensed. 
A careful study will show that the existing laws are not adopted 
to present conditions and often work unnecessary hardship to the 
nurseryman. 
ist Under your state law what insects and diseases are classed 
as dangerously injurious to nursery stock ? 
(Following the names of the insects or diseases is the number in¬ 
dicating the times mentioned in replies). 
It is interesting to note that San Jose scale was the only insect 
mentioned in every reply as being dangerously injurious. Usually 
from two to six insects were mentioned in each reply.
