FOOD OF THE ANIMAL. Beasts fed upon straw, or straw and turnips, 

 furnish an inferior manure altogether to cattle receiving grain and cake. 

 This difference is recognised by practical farmers everywhere. 



The difference in value between the excrementitious residue of a ton of 



w, a ton of turnips, of barley meal, of linseed-cake, and a variety of 



other substances employed as cattle foods, has been estimated by Sir J. B. 



Lawes, and reduced to a money standard. It is not necessary that these 



figures should be accepted as precisely fixing the commercial value of the 



manuriul residue left by the consumption of the various foods mentioned. 



The figures are based upon chemical data, but in each case will require to 



liscounted rather heavily to compensate for the inevitable, as well as 



preventible, waste that always occurs.
