It seems there is not a portion of the American Continent - at least in the Atlantic portion where the yellow locust is free from the borer. In Canada it seems as bad as further south, judging from a remark by Dr. Beadle in the Forestry Congress at Montreal, who said that the town of St. Catharines at one time had so many locust trees that people could feel their perfume even while approaching the town from a distance, but he did not think they could find a dozen now, as they had been destroyed by the borers and other insects.
