Cattle mange in Canada is confined to certain parts of southern 

 Alberta and south-western Saskatchewan. Affected areas have been 

 under quarantine prohibiting, the movement of cattle except for 

 immediate slaughter at a designated abattoir, or unless they have 

 been twice dipped under the supervision of an officer of the Department 

 of Agriculture. By these means the extent of infection has been 

 gradually lessened, and the quarantine restrictions have been removed 

 from certain areas. 



In 1920, a determined effort was made to stamp out the disease. 

 The whole of the affected area was sub-divided into dipping districts, 

 and each district was equipped with a staff selected by the farmers to 

 supervise the construction of new dipping vats where necessary and 

 the repairing of existing vats, and to maintain a general high standard 

 of thoroughness in dipping. The Department granted about ;£80 

 towards the construction of new vats, and it is hoped that it will 

 be possible to dip twice all the cattle in the mange area, and that 

 subsequently the restrictions now in force may be abolished.
