1,600 feet were found oak and birch of sprout size in mixture, 

 the number 5 representing the size class. Oak predominates, 

 since the letter "E," representing oak, precedes the letter "S," 

 representing birch. 



FOREST TYPES. 



On account of the difference in topographical and climatic 

 conditions, the types of Plymouth County vary to a consider- 

 able extent from those of Worcester County. Following is a 

 list of types used and a brief explanation of each:- 



Wliite Pine. This type consists of white pine in pure 

 stands, that is, in stands made up of 80 per cent, or more of 

 the one species. There is still a considerable amount of this 

 type found throughout the county in spite of repeated cuttings 

 and fires. It may be safely stated that there are several million 

 feet of this type of good merchantable size, although it is some- 

 what scattered and found as a rule in stands of small areas. 

 '/ Pine and Oak. Stands of this kind are made up of 70 per 

 cent, or more of white pine and oak in mixture. It is a com- 

 mon type. Sometimes the proportion of oak is greater than 

 that of pine, while at other times there is about an equal 

 amount of each. In all cases, however, the oak and pine in 

 combination form at least 70 per cent, of the total stand, the 

 remainder being made up of maple, pitch pine and unimportant 

 hardwoods. This type is generally found on the higher gravelly 

 lands. 



Pine and Maple. Substituting maple for the oak, this type 

 is similar to the preceding. It is not so common as that of the 

 pine and oak, and is generally found in low or swampy lands. 



Oak. This forms the largest type. It embraces stands 

 made up of 80 per cent, or more of oak. A very large pro- 

 portion in size class 5 is made up of the so-called scrub oak. 

 More than one-half of the total for the county is of a diameter 

 size too small for cordwood. There is, however, a considerable 

 amount large enough for saw-logs. 



Maple (Swamp Type). Consists of nearly pure stands of 

 maple. This type is found on low, wet land, and is fairly com- 

 mon. A good proportion is made up of species of cordwood 

 size, with a moderate representation of the larger size classes. 



Pitch Pine Type. Next to the oak this is the largest indi-
