 would want it ; and just such is the case 

 w'ith our tree. The supply of sap is 

 scanty, and therefore, the only possible 

 means of preserving all its members, 

 (supposing such preservation necessary), 

 is bi/ an equal distribution ; for if one gets 

 more than its proportion, it robs ano-
