tree groAvs on the flats southwest of the greenhouse. In the arboretum also 

 grow small samples of black mulberry. 



NETTLE.TREE. 



See hackberry. 



OAK, BLACK — Quercus coccinea, vai: tincloria. 



This is a common tree in many portions of our State. To be understood 

 and distinguislied from some other oaks, it must be studied. 



Good specimens may bo seen a little nortli and also northeast of AVilliams 

 hall. 



OAK, BURR— Quercifs inacrocarpa. 



This becomes a large valuable tree and thrives in deep, rich, rather low 

 land. The wood is hard, strong, and durable. Some fine trees can be seen 

 north of the barn of Secretary Baird and west of the arboretum ; also in the 

 two west rows of the arboretum where the acorns were planted in the autumn 

 of 1875. 



O^iK, CHESTNUT— Querctw I^rinus. 



This middle sized tree grows sparingly along streams. Small specimens 

 grow along Cedar river, one south of the garden barn on the flats, one in the wild 

 garden or rock work. 



See burr-oak. 

 See black-oak.

OAK, RED— QwercMS rubra. 



This tree is of rapid growth and is coarse-grained. The wood is not very

 and VVillianis hall. 



OAK, SCARLET— Quercus coccinea. 



This is a handsome tree much resembling the black oak. The wood is of 

 little value. 



A fine specimen grows west of "Williams hall and within four rods. 



O-Uv, SWAMP-WIIITE— Quercus bicolor. 



This grows on low grounds, where it becomes a tail tree with valuable, dura- 

 ble timber. 

 For a sample see side of gravel road within half a mile west of the College. 



OAK, AVIIITE— Quercus alba. 



This is another very valuable tree, found in great abundance in most parts 

 of the southern peninsula. It disappears as we go north among the forests of 

 pine. It is one of our most valuable trees for a great many purposes ; for 

 floors, doors, and furniture, especially when cut to show the silver grain or
