LEGEND 



I Area in which the SUGAR MAPLE is abun- 

 dant (Acer barbatum, Michx.} 



jArea in which the SUGAR MAPLE is found 

 only locally. 



It occurs throughout this State, growing to an average height 

 of from 50 to 80 feet and a diameter of 2 to 3 feet, but is most com- 

 mon in the mountains. It is a small tree in the Piedmont plateau 

 and reduced to a mere shrub in the coastal plain region, where it 

 is confined to borders of streams and swamps. (Fig- 6.) 



The sugar maple bears seed about every third or fourth year. 

 Seedlings are very abundant in the woods, and bear dense shade 

 remarkably well; they spring up quickly in thinned woods, also, 

 and where lumbering has been in progress.
