 the valleys of the sand dunes, and producing fruit id great abund- 

 ance. One tre* measured 8 feet in circumference, 3 feet above tho 

 surface. The lee siJe of these dunes is covered more or less with 

 trees and shrubs of the general character of the flora of tho region, 

 imbedded in the sand sometimes half their height.

or Pin Oalc. Ann ^ r ^ or> rpjj e oa k family is abundantly represented in the southern 



peninsula, forming a great part of the forest timber. Still the im- 

 mediate shore of L. Huron from Bay county to the Straits of Mack- 

 inac is apparently entirely destitute of oaks. Thence northward 

 along St. Mary's river Q. rubra is the only species, which is quits 

 common but never attains a large size. Southward this species is 

 of rarer occurrence, but is replaced by other and more valuable 

 species. At Traverse City Q. alba and Q. coccinea make their most 

 northern appearance as far as observed. There they are about 

 equally frequent, growing in a sandy soil, sometimes in patches 

 surrounded by the pines and more or less dispersed amongst them, 

 the former forming a large and shapely trunk, the latter being a 

 smaller, but well proportioned tree. South of this the species mul- 

 tiply both in numbers and frequency of occurrence.
