Agriculture. Advice on dealing with special problems can be ob- 

 tained by writing to the Bureau of Biological Survey. If all pos- 

 sible preventive measures are employed, it will be no more necessary 

 to employ aggressive measures to protect poultry against the attacks 

 of crows and magpies than against those of hawks and owls. 



Figure 5. — Commercial basket trap for hawks, with pigeon for bait. As the hawk de- 

 presses tbe wire-floor trigger, the jaws with accompanying netting are released upward
