rapidly lumbered, and will be removed within two years. (See Plate 

 XVIII, Figs. 1, 2.) 



Two sub-types of the Swamp Timber are distinguishable; the first 

 has White Pine as the predominant species, and the second, Spruce. 



WHITE PINE. White Pine was once quite a common tree along 

 the streams and rivers of Garrett county, and was one of the first 

 timbers removed. It reached the best development and grew in 

 almost pure stands on the moist level lands surrounding the swamps 

 and mountain meadows. The areas occupied by this growth were 

 never more than a few acres in extent, and the number of such areas 

 was small. As a scattered tree along the streams and mountain 

 slopes it was fairly common and reached large sizes. The reproduc- 

 tion of this pine is fairly abundant, considering the numbers of old 

 trees and the treatment it has received. Young seedlings are found 

 throughout the county and are making a good growth. (See Plate 

 XVIII, Fig. 12.) The last group of pure White Pine in the county 

 was cut recently. 



The following table is the result of the measurement of three acres 

 of this sub-type:
