remains to be considered. It is impossible to place a precise value 
upon any unplanted land for the growing of a particular species, 
it is true, but it certainly seems desirable to obtain something 
more definite than the bare classification of a locality as good, 
bad or indifferent if possible, and, at any rate, no objection can 
exist for the reasons which lead to any classification being given. 
The only method which seems in any way to meet the require- 
ments of the case is that of placing unit values upon the various 
factors of locality by points, as shown in the following Table :—
