species jnst mentioneil. Trees of all sizes are represented, from one-year- 

 old seedlings to mature specimens of the original forest. In the bottom 

 lands, the reproduction is very good, consisting chiefly of red gum. elm, 

 and ash. On the better-drained areas, the young growth consists largely 

 of sprouts of chestnut, oak. hickory, and maple. The frequent opening 

 of the forests affords plenty of light for undesirable tree species to come 

 in, such as the dogwood, black gum, mountain laurel, persimmon, chin- 

 quapin, and blue beech. These unimportant species, in addition to the 

 scrub pine on well-drained areas, form 60 per cent of the stand, and in 

 some places the proportion is even greater. 



The climatic position of St. Mary's County is so favorable that it 

 exhibits floral features similar to those of the adjacent Southern States. 

 On this neck, loblolly pine finds its northern limitation. The following
