are not without cost in time and machine wear, however. The result is that 

 farmers are inclined to use only the larger, more productive fields as the 

 travel distance increases. This means that pieces of say three acres, in a good 

 farming area, will be used, but a piece five miles up in the hills might have 

 to be at least ten acres to attract a user.

 having numerous farms of good size. 



Another major generalization about renting is that it is very imperfect. 

 Much use of others' land is very light — buying standing hay is too light
