Abstract
THE history of agricultural pests suggests that there is a strong tendency for any creature imported from a foreign country, so long as conditions of food and climate favour its survival, to outrival native pests and to become a real burden in the land of its adoption. So often has this happened that many nations have taken the warning to heart and have adopted laws forbidding, without permit from the proper authorities, the importation of foreign creatures. Great Britain, always a little slow in admitting that science can teach it, has been content to place a ban upon certain insect pests which are liable to come unawares with food materials or other vegetation, but has made no provision against the open and deliberate importation of animals which harbour the possibility of much damage.
