entry into Canada, which if found infested with pests or diseases may be refused 

 entry, treated or destroyed. They also are of particular value in connection 

 with the handling of shipments not covered by any special regulation or order, 

 such as grains infested with weevils, broom corn, dried fruits, etc. Provision 

 is also made for the inspection of export shipments, the powers of inspectors, 

 interfering with an inspector in the performance of his duties, holding of infested 

 shipments, the right to trespass, the selling of infested material, the importation 

 of plants for scientific purposes, and the paying of compensation. 



The foreign and domestic regulations deal with specific problems; they 

 may be increased in numbers, amended or modified as occasion demands. They 

 are issued in separate form and, it is hoped, are worded so as to be readily 

 understood by the general public. 



In adopting this form, the Department is of the opinion that the average 

 individual may take a greater interest in the safeguards that have been enacted 

 for his benefit. An inquirer will be able to see just what he may or may not 

 do without the necessity of wading through endless pages of laws which are of 

 no particular interest to him. 



Under the foreign regulations the importation of nursery stock from foreign 

 countries is governed. All plants for ornamental purposes or propagation, 

 except seeds, are now classified as nursery stock and permits are necessary to 

 import such shipments. Nursery stock from countries other than the United 

 States may enter only through certain ports, and all shipments are subject to 

 inspection. It is hoped by this means to prevent, if possible, the further intro- 

 duction of noxious pests and diseases. 



The foreign regulations also restrict the importation of plants from the 

 Hawaiian Islands on account of the Mediterranean fruit-fly; the importation 

 of nursery stock, forest and quarry products from the New England states on 

 account of the gipsy and brown-tail moths; the importation of corn, cut flowers 

 and other plants from the European corn-borer areas in the United States. A 

 total prohibition has been placed on the importation of potatoes from countries 

 and localities infected with the potato wart disease; all five-leaved pines and 

 currants and gooseberries from all parts of the world on account of the white 

 pine blister rust, chestnuts and chinquapins from Asia and the United States 

 on account of the chestnut bark disease; European buckthorn and certain 

 species of barberries from all countries on account of the crown rust of oats 

 and the black-stem rust of wheat; alfalfa hay from the alfalfa-weevil-infested 

 districts; plants with soil from Asia on account of the Japanese beetle and 

 other soil-infesting insects; all species and varieties of douglas fir, hemlock, and 

 larch from countries other than the United States on account of the newly 

 discovered douglas fir disease; peach stock and hazel, cob and filbert from 

 certain states into British Columbia on account of peach yellows and eastern 

 filbert blight. 



The domestic quarantines deal with the movement of nursery stock in the 

 apple-sucker-infested areas in Nova Scotia; the movement of corn from the 

 European corn-borer areas in Ontario. They also coincide with the foreign 

 regulations prohibiting the movement of pines and currants and gooseberries 

 into Western Canada from the white pine blister rust areas in the east, and 

 similarly with the importation of European buckthorn and certain barberries 

 on the prairies, and peach stock and hazel, cob and filbert into the Province of 

 British Columbia from Eastern Canada.
