Distribution. 



The trees of Cecil county may be arranged in two groups, based 

 on their commercial importance and their abundance. 

 I. — Important Commercial Trees. 

 II. — Inferior Commercial Trees. 

 The first group contains those species which furnish lumber, posts, 

 ties, or telegraph poles. The second group consists of those species 

 which yield cordwood. 



IMPORTANT COMMERCIAL TREES. 



The abundant trees of this group are Chestnut, Tulip-tree (Yellow 

 or White Poplar), and White, Eed, and Black Oaks. They are found 

 in all parts of the county in varying quantities. The tables on pages 

 299 and 301, based on a careful measurement of seventy-five acres 

 of the two types of forest, show the abundance of the species, the 

 relative proportion of each, and their average diameter. Under 

 White Oaks are included White, Post, and Swamp White Oaks. 

 Chestnut Oak has been separated from the other White Oaks be- 

 cause it furnishes tan-bark. The Black and Bed Oaks comprise the 

 remaining species of Oaks found in the county. 



Chestnut predominates on the better soil of the shore-timber, while 

 in the Barrens Bed and Black Oaks are the most abundant species. 

 The shore-timber has 52 per cent of commercially important trees 

 and the Barrens 87 per cent. Tulip-tree is not found in measurable 

 quantities on the poor soil of the Barrens, but is uniformly distributed 

 through the moister shore woodlands, which are especially adapted 

 to its growth.
