(Middle and Upper Divisions.) 



Eupatorium sessilifolium L. Euphorbia corollata L. 



E. perfoliatum L. Castanea vesca L 



Oxydendrum arboreum DC. Pmus mitis Michx. 

 Kalmia latifolia L. 



Upper Subcarboniferous.— Heavy beds of limestones, 

 found only on the highest knobs. 



Hypericum nudicaule Walt. Q. coccinea Wang. 



Qnercus nigra L. Juniperus Virgimana L. 



The Birdseye and Upper Birdseye, both pure limestones, 

 are covered by cedars, to the exclusion of nearly everything 

 else. On the Upper Subcarboniferous limestones cedar is 

 present in large numbers, but does not attain such size as on 

 the other formations ; at every point at which I examined the 

 Upper Subcarboniferous, if not covered with cedar, Hyperi- 

 cum nudicaule W alter is found in the greatest abundance. 



The Oaks are represented by some species on most of the 

 formations. Qicercus alba L. is found in numbers on the 

 Lower and Upper Hudson River Beds, and on the Medina 

 sandstone, but seems to prefer the siliceous limestones at the 

 base of the Trenton. j£. obtusiloba Michx. is found on all 

 formations which give rise to a light or sandy soil. ^ Except- 

 ing a few small trees on the Black Slate, J^. hnbricaria Michx. 

 is found only on the Lower Hudson River. So far as can be 

 determined "from observations in this county, J^. nigra L. and 

 J£. coccinea Wang, are characteristic of the Upper Subcar- 

 boniferous. - T * 



Fagus ferruginea Ait. prefers a siliceous soil ; and in Lin- 

 coln is most abundant on the siliceous limestones of the Tren- 

 ton, but in the surrounding counties the beech forests are on 

 the Middle Hudson River Beds— the " siliceous mudstones 

 of the old Kentucky reports.

EDITORIAL. 



The Gazette is naturally deeply interested in the success of the Ag- 

 ricultural Experiment Stations, because the establishing act makes sue 1 

 extensive provision for botanical investigation. It is because of our grea 

 interest in their work that we have ventured to express our opinion as 

 to its direction and scope, and particularly as to the mode of presen 

 tion. It seems that some of the experiment stations think our advic
