worthley: corn borer quarantine 
149 
tions and officials in southern Ontario; the placing of cloth warning 
signs at all road intersections leading out of the quarantined area; and 
the use of large roadside banners on the main automobile highways. 
The co-operation of the steamship and railroad companies was sought 
in connection with the source of supply of table corn for the lake boats 
and dining car services, and arrangements were made whereby all corn 
used for these services was purchased outside the area actually infested 
by the European Corn Borer. Inspectors were stationed at the larger 
shipping centres, such as Windsor, Sarnia, Hamilton, Toronto, etc. to 
watch the shipments of corn forwarded by express or boat. It must be 
stated in this regard that the transportation companies co-operated in 
this work to the fullest extent possible and endeavored to ascertain the 
nature of all shipments previous to accepting the same. In one in¬ 
stance corn was found in a package labelled fresh meat. 
During the sweet corn season inspectors were stationed on the main 
automobile highways, on Saturdays, Sundays and holidays. No in¬ 
fested corn was seized on the highways leading out of the lightly infested 
area, but seventeen infested ears were seized on the highways leading 
from the double quarantined .area. 
In addition to the foregoing a watch is maintained in the shipping of 
live stock, particularly hogs, as corn on the cob is frequently fed to these 
animals en route. It has also been necessary to keep in touch with the 
contractors who handle the manure from the stock yards at a point like 
Toronto, as it has been found that manure is sometimes shipped in car 
load lots for some distance, to market gardeners, fruit growers, etc. 
Inspectors are also stationed at fall fairs and winter exhibitions to see 
that the quarantine is maintained. In accordance with the quarantine, 
provision is made for exhibits of seed com on the cob to be sent to fall 
fairs, etc., for exhibition purposes only, these are inspected on arrival at 
the fair and if they originated in the quarantined area, must be returned 
to that area at the close of the fair.
