 animal and vegetable bodies. Whence it may be concluded, that ve- 

 getables and animals during their growth increafe the quantity of 

 matter fit for the more nutritive food of organized bodies, or of that 

 which is lefs decompounded ; while they muft at t<he fame time occa- 

 flonally form or elaborate a part of the materials, of which theyconfifl 

 from the fimple elements of hydrogen, nitrogen, carbon, phofph

I. One method therefore of increafing manures may be by repeat 



dly propagating and deflroying vegetable crop 



by railing thofe^

3* Another mode by which vegetable matter may be decompofed 

 in the fummer months, and at the fame time the quantity of manure 

 increafed, is by the depredation of infe£ls, as is feen in wood, which
