east Texas. Both leaves and acorns have been found in the 

 Pleistocene of North CaroHna. 



Persea borbonia Spreng (?) 



Somewhat doubtfully determined leaves of this species occur 

 at this locality. In the recent flora it ranges from Virginia to 

 Florida and Texas. It has not certainly been found fossil before 

 but allied Persea pubescens (Pursh) Sargent has been found in the 

 Pleistocene of North Carolina and Alabama. The separation 

 of the two on the basis of leaves alone is attended with some 

 uncertainties.

NATURE TRAILS AT WALKING CLUB CAMPS 



Raymond Torry 



Among a large number of outdoor study groups, throughout 

 the United States, and even in Europe and Asia, which have 

 adopted the methods of Dr. Frank E. Lutz, Curator of Ento- 

 mology at the American Museum of Natural History, in labelling 

 natural exhibits "in place," on Nature Trails, are two of the 

 largest of the walking clubs of the New York City metropolitan 

 district, the New York Section of the Green Mountain Club and 

 the New York Chapter of the Adirondack Mountain Club. 



Nature Trails have been started at the Wyanokie Lodge, the 

 gathering place of the New York Section of the Green Mountain 

 Club, three miles west of Wanaque-Midvale, in Passaic County, 

 on the Greenwood Lake division of the Erie Railroad; and at 

 Camp Thendara, the Section's all year camp on Lake Tiorati, 

 in the Harriman State Park, nine miles southwest of Bear 

 Mountain.
