great plan of nature, and as connected with the 
benefits and injuries done to the productions used 
by man, the influence of its members on his feel- 
ings and enjoyments, and their effects on the 
scenery of their various native countries, we shall

food, and the manner of searching for it, are 
nearly the primary causes of all the benefits or 
injuries received from birds. In this order some 
feed entirely on grains and seeds, others on the 
buds and tender shoots of plants and trees, others 
on various fruits and berries, and some again, on 
all these substances indiscriminately. Wherever 
any production is cultivated extensively, consider- 
able ravages may be committed at some period of
