CONTROL OF INJURIOUS MAMMALS 165 



Department of Agriculture and other agencies, by means of bulletins, 

 circulars and magazine and newspaper articles, the great majority of 

 them still persist in shooting these birds at every opportunity. The 

 wholesale destruction of the natural enemies of rodents has made the 

 control of these pests much more difficult and expensive, and costs the 

 farmers far more than the possible losses of poultry would have 

 amounted to, and most of the poultry losses could be prevented by 

 proper precautions, without destroying useful birds and mammals 

 that prey upon the rodents.
