268 THE FORESTS OF ALLEGANY COUNTY 



other cases similar hills bear a growth chiefly of conifers on their 

 north slopes and a deciduous forest on their south slopes. As a, rule 

 the larger mountain slopes bear a variously mixed growth of conifers 

 and deciduous trees, sometimes evenly mingled or with the conifers 

 in alternating vertical belts. The slopes near the larger waterways 

 also bear conspicuous fringes of conifers, which give way to the 

 hardwoods higher up on adjacent slopes. 



COMPOSITION OF FORESTS. 



The peculiar position of Western Maryland, intermediate be- 

 tween the North and the South, gives Allegany county a forest flora 

 rich in species. The higher summits, coves and valleys exhibit a 

 climate and soils closely similar to those of the more northern states, 

 while the climate and soils of the lower valleys, glades and hills are 

 characteristic also of the adjacent southern states. As a result, there 

 is a conspicuous association of northern and southern tree species. 

 This association is of more than passing interest, since the kinds 

 represented are of economic importance. Conifers and hardwoods 

 of the middle South and North mingle here almost on the same 

 ground.
