 as these birds attack grains or seeds rather than fruits. 



" To sum up, we must conclude that in the case of 

 these birds of mixed qualities it is as dangerous to 

 acquit them entirely as it is to condemn them without 

 appeal. And it is all the more difficult to decide, as 

 many of these gramnivorous birds not only eat insects

" Here are some conclusive proofs. 



" In Prussia, Frederick the Great observing one 

 day that the sparrows were far too familiar with his 

 cherry-trees at Potsdam, resolved to exact a full

 all quarters, the king himself recognised his mistake, 

 and the sparrows were reinstated at a very great 

 expense. A little more, indeed, and apologies would 

 have been offered to them.
