The Codling Moth, Carpocapsa pomonella, was in all probability first introduced into the United States, but Canada has as you all know sustained her full share of injury from its ravage?. These two species have been brought to our shores from the mother country, and they are by no means the only ones that have been introduced from Europe or Palsearctic regions, and, I fear, those ^J*1^ that we now have with us will not be the last to come this way. The latest and most serious introduction of all, the San Jose scale, Aspidiotus perniciosus, is in all probability another contribution from the Palfeirctic region, as I have been able to prove almost conclusively that it came to us from Japan, and we therefore received it from the west instead of the east. Recent experiences are amply sufficient to show that it will destroy the orchards of Canada as well as those of the United States, within whose domains it first made its unwelcome appearance. The foregoing illustrations will certainly be sufficient to convince anyone that we cannot by simple Legislative or Parliamentary enactment erect a Chinese wall, so to speak, that shall keep Canadian insects, whether native or introduced from making their way into the United States, or similar species escaping from the latter into Canada. We in the United States are more likely to import more insect pests than you, and, owing to our geographical situation, will suffer most from their depredations, bub, put the matter as we will, we are much in the po
