rather low and one-third of it goes into the silo. If we were unable to 
seriously check the development of the pest under these conditions, it is 
bound to be much less satisfactory in counties farther west where only 
one acre in seventeen goes into the silo and where much of the com is 
cut by hand, the stubs being high. 
We must infer from this test that burning is desirable, but to be most 
effective must be supplemented by other methods more difficult to 
incorporate into practice. These would include more general use of 
corn binders and handling of the crop in such a way that the surplus 
could be burned. The 1924 program includes burning for all infested 
townships in the ten counties. We do not expect to stop the progress 
of the borer but if its normal multiplication can be reduced thereby to 
the extent of retarding its increase and spread we feel that our efforts 
will be well repaid. 
CORN BORER LEGISLATION IN CANADA 
By L. S. McLaine, Entomological Branch , Ottawa, Canada 
Abstract 
European Corn Borer legislation in Canada is divided into two main groups, foreign 
and domestic quarantines. In 1919 an embargo was placed on the infested areas in 
Massachusetts and New York, which prohibited the importation of products likely 
to harbor the pest. This regulation has been amended each year and practically 
compares with quarantine 43 of the United States Department of Agriculture. 
Broom corn from countries other than the United States may not enter Canada, 
unless it is accompanied by a certificate of inspection and sterilization, issued and 
signed by an officer of the United States Department of Agriculture, as no facilities 
are available for the treatment of infested shipments at Canadian seaports. 
With the discovery of this insect in Ontario in 1920, a qurantine was placed on the 
infested areas prohibiting the removal of corn. This quarantine has been amended 
each year to include the newly infested districts. In December 1923, 162 townships, 
covering 12,616 square miles, were under quarantine. Eight townships found in¬ 
fested in 1923 will shortly be added, to the quarantined area. 
The enforcement of the quarantine consists of issuing press notices; distribution 
of quarantine maps to post offices, banks, transportation companies, produce dealers, 
etc.; placing of warning signs at road intersections leading out of the area and road 
side banners on highways, etc. 
Inspectors are stationed at larger shipping centres, on main automobile highways 
and attend fall fairs and exhibitions etc. 
The history of European Corn Borer legislation in Canada is divided 
into two main groups, foreign and domestic quarantines. When it was 
realized that this insect was a serious menace to agriculture in general, 
and upon its discovery in Central New York early in 1919, steps were
