The transport of produce makes the farm all the 

 more profitable if there are good wagon-roads or 

 navigable rivers close by. For by both these many 



iiings are, as we know, brought to and from a 



arm. 



Again, the products of the farm are influenced 

 by the way in which your neighbour's land is 

 planted. If, for instance, he has an oak-grove on 

 the common boundary, you would be wrong to 

 plant olive trees on the edge of such a wood, for 

 these have a natural antipathy to it so great that, not 

 only do they bear worse, but even, in their efforts 

 to escape, bend away inwards towards the farm 

 precisely as does the vine if planted near cabbages. 

 Like oak-trees, walnut-trees near your farm, if of 

 large size and standing at little distance from one 

 another, make its margin totally unproductive.

These are divided by some into two parts, namely 

 (i) men who work, and (2) men's tools without 

 which they cannot work; others divide them into
