266 ESTIMATION OF STANDING TIMBER 



The variety of the timber increases. 



The topography is more mountainous or varied, resulting in a 



greater diversity of types. 

 The number of products required increases. 



Finally the degree of accuracy required, other things being equal, 

 will depend upon the stumpage value of the products to be estimated, 

 as influenced, first, by the character of the timber itself, and second, 

 by the unit price of the product. In the earlier days crude and inaccu- 

 rate methods of timber estimating were justified by the low price 

 per acre and per thousand feet at which stumpage changed hands. 

 With record stumpage prices running up to S27 per thousand feet for 

 white pine in state auctions in Minnesota, in 1920, a degree of accuracy 

 is justified which would not be thought of by old-time timber cruisers.
