Therefore, the optimum ratio of cows to cropland under the 

 assumed conditions and prices is between 0.35 cows per acre, and 

 0.40 cows per crop acre. 



Figures 11, 12, and 13 describe the optimum ratios of cows to 

 cropland and different ratios. 



To use these figures: 



1. Locate present ratio of cows to cropland on vertical axis. 



2. Locate price ratio on horizontal axis. 



3. Plot a point having the coordinates (price ratio, cow to crop- 

 land ratio) found above. 



4. Find the line corresponding to the milk price. This line con- 

 nects all the ratios which would be optimum at this milk 

 price. 



5. If the point located in Step 3 is above or to the right of the 

 milk price line it will pay better to add cropland. If below or 

 to the left, it will pay better to add cows.
