rant it. These tables show the proportion of forest land to 

 non-forest land, and also the relative proportions of the indi- 

 vidual types of the forested areas. The tables alone could not 

 be made to show the proportion of the separate type size 

 classes, so they have been supplemented by diagrams from 

 which may be formed an idea of the relative amounts of mer- 

 chantable and non-merchantable timber of each type in each 

 town. In these diagrams the proportion of non-merchantable 

 sizes is represented by the inked portion of each line. 



In arranging these diagrams size classes 1 and 2 of the white 

 pine and pitch pine types were combined and classed as mer- 

 chantable, while in the remainder of the types classes 1, 2 and 

 3 were combined and classified in the same way. The remain- 

 der of the size classes was combined in each type and classed 

 as non-merchantable. It will be noticed from this explanation 

 that in the case of the hardwoods and mixed hardwoods and 

 pine, class 3, or cordwood class, has been listed as merchantable, 

 while in the case of the pines only classes 1 and 2, containing 

 lumber large enough for saw logs, were so listed.
