HAWKS THAT ARE THE FRIENDS OF MAN 

 LargCj conspicuous hawks are all of great economic value, being tile principal natural check on the hordes of 

 noxious rodents that, if unmolested, would soon render agriculture unprofitable. The large soaring, circling 

 hawks of the open country are not the ones that molest the farmer's poultry, but are the ones that hold in 

 check the field-mice, gophers, ground-squirrels, mole-crickets and grasshoppers that annually cost the country 

 many millions of dollars through their depredations on crops, orchards and forage.
