418 APPENDIX III 



In Alberta the Noxious Weeds Act of 1907 (as amended in 

 1908) schedules twenty-two noxious weeds, and makes their 

 destruction by all owners or occupiers of land compulsory. It 

 further provides that all earthworks owned by railway or irriga- 

 tion companies must be sown with White Clover, Timothy, or 

 Western Ryegrass. Inspectors have power to order the partial 

 or complete destruction of grain or hay crops containing noxious 

 weeds. The sale of seed containing a greater proportion than 

 5 per 1000 of noxious weed seeds is prohibited, and the ger- 

 minating power of all weed seeds must be destroyed before 

 cleanings, &c., can be removed from any premises. Thrashing- 

 machines must be thoroughly cleaned before removal to another 

 place, and the thrasher must deliver the grain in such a condi- 

 tion that it contains not more than 10 per cent of noxious 

 weed seeds other than Wild Oats. 



In Prince Edward Island the Noxious Weeds Act of 1909 

 schedules seven weeds, and makes their destruction before the 

 seed ripens compulsory. The provisions of the Act are in 

 similar terms to those in force in the other Canadian provinces. 



AUSTRALASIA 



The Federal Quarantine Act, No. 3 of 1908, prohibits the 

 importation into the Commonwealth of the seeds of no less 

 than eighty-two species of weeds, among which may be men- 

 tioned Burdock, Charlock, all Thistles, Corn Marigold, Dodder, 

 Fumitory, Poppies, Spurrey, Ragwort, Hemlock, Field Bindweed, 

 Cleavers, Pepperwort (L. Draba and L. campestre), Black Bind- 

 weed, Sheep's Sorrel, and certain Docks. All seeds imported 

 into the Commonwealth are required to be " sound, clean and 

 new," and therefore tests of their viability are sometimes made, 

 and they are cleared from bond only when the Commonwealth 

 Inspectors are satisfied that seeds of the eighty-two species of 

 weeds referred to are not present. 



In Victoria^ the Thistle Act of 1890 includes among other 

 species Cnicus lanceolatus, Onopordon Acanthium, and Cnicus 

 arvensis as noxious weeds; and the Act of 1891 empowers the 

 Governor in Council to proclaim any plant to be a Thistle within 

 the meaning of the Act of 1890. Occupiers of land are com- 

 pelled to destroy all Thistles thereon, and upon half of any road
