EXPECTATION VALUE OF STAND 63 



7. In the above case the cost value So of the land was used. 

 In most cases it is but natural that this should be so. But where 

 the cost value is practically zero, quite common where the land and 

 timber were bought together and only the merchantable timber con- 

 sidered in the price, the cost value is misleading, the land may read- 

 ily be worth five or ten dollars an acre and so have an accepted sale 

 value. 



In such cases the sale value, Ss, is used. Occasionally the land 

 has neither cost nor sale value which could be agreed upon, for in- 

 stance, state and national lands, remote mountain or non-agricultural 

 land. Here the temptation is to ignore the value of the land entirely. 

 This is wrong since any land which can and does, or actually has 

 produced a crop of timber having value, has value itself. Incon- 

 sistency here is liable to lead to trouble for sooner or later the value 

 of these very lands may come in question. In such cases, the Se 

 properly based and discounted should be substituted as S-. 



To employ Se without deductions is hardly advisable since Se 

 is rather the maximum value of the land for the particular purpose 

 and to employ a maximum price in these calculations is liardly safe 

 or satisfactory.
