 tlie value of the <»razini» (m one acre is $4.47. 



The peas were planted for their fertilizinj;" valne an<l 

 tlie hntter removed practically none of this. Hence the 

 cost of iirowini;' tlie peas should be char<»ed in the fer- 

 tilizei- hill of tlie foilo\vin<»' crop, and not to the butter 

 produced. However, if it he insi^^ted that this is a proper 

 charge against the cows the expense consists only of 

 the cost of seed, labor of dropping and of covering, tlie 

 total being somewhat less than a dollar |>er acre. 



If we charge all of this expense of growing the peas to 



the cows giving milk and entirely neglect the gains made 



in live weight (the \alue of which was greater than the 



cost of growing the peas) the cost of concen- 



trate^d feed and of pasturage* was 8 cents pei* 



IH)nnd of butter. Balancing gains in live weight 



igainst cost of making the pea crop, we have 2.b 



cents as the cost of purchased food per pound of butter. 



Since there are more farmers interested in beef pro- 

 duction than in commercial dairying, we have made an 

 estimate as to the amount of growth of beef cattle that 

 might be expected on an acre, using Thome's figures as 

 to the relative amounts of food required to make a pound 

 of butter and of beef. By this method we estimate that 

 an acre of grazinu" of this character made without the 

 aid of anv other fo;)d, animal products equal to about 

 80 pounds of increase in live weight. This is con- 

 fessedly only an estimate but it is in accord with the 

 small amount of data from other sources which is avail- 

 able on this subject.
