A form of brushwood that has many points of interest are 
the fence-rows. These straggUng and interrupted growths are 
distinguished for the great variety of species occurring in them. 
All the upland shrubs of the region, from the xerophilous haw- 
thorns and sumachs to the decidedly mesophytic species of Ribes 
are mingling in this formation, without any apparent distinction, 
of various associations. With the uplands species are commonly 
found Vitis, Ampelopsis and similar creepers, that are more often 
found in the bottom lands, and occasionally a dogwood flourishes 
in such places far away from its swamp. As to what may be the 
cause of the comprehensiveness of this fence-row vegetation, I 
have no theory to offer.
