PLATE XVII. 



Stand shown in Plate XVI after a combined first cutting and improvement thinning. Most of the knotty 

 dominant trees have been cut, leaving the stand formed entirely of slender, clean-stemmed codomi- 

 nant and intermediate trees. These, with increased diameters, will yield from 3 to 3% nearly 

 clear logs, which will saw out approximately the same type of wood as that shown in Plate IX-B. 

 More than 3,000 feet D.-S. per acre were removed from the stand in this cutting. The average log, 

 however, scaled less than 12 feet. (Author's illustration.)
