 among the remains, it seemed unnecessary to associate the filling in of the chasm 

 with an invasion of the ocean. Enough had been seen to convince us that a fresh

 of the hill-top, hence a general inundation of the whole surrounding country,

Large blackened fragments of trees found at the west end of the darkly discolored area of layer 3 

 at about B and C, 3, 12. The now dry and cracked central fragment about 3 inches thick, has been 

 rubbed smooth around its circumference by an erosive agent which has failed to remove the compara- 

 tively soft bark facing the specimen. The background consists of darkened earth characteristic of 

 the layer.

Number and Variety of the Remains. 



Summing up the mammals and reptiles described in an associated paper 



by Professor Cope, and the plants noted below, kindly identified by Messrs. 



Thomas Meehan and Stewarclson Brown of the Academy of Natural Sciences of 



Philadelphia, 1 the work presents 377 individuals and 66 species, of which latter 



1 Mr. Meehan writes as follows : "There appears to be no great variety in the collection examined by me. 

 The bulk of the seeds are young (July?) conditions of the hickory, Carya porcina Nuttall, and many of the 

 thicker twigs belong to this hickory; beech nuts, immature ( July)'condition and beech twigs; Pinus rigida ; 

 Ouercus palustris, the pin oak ; seeds with a tendrill of Ampelopsis, apparently the Virginia creeper, A. qidn- 

 quefolia (one of the seeds had been gnawed by a small rodent). The mosses all appear to be the common 

 Sphagnum of our swamps. A thorn, slender and slightly curved, belongs to Cratcrgus, and there is an impres- 

 sion of a Cratcegus fruit — probably the cockspur thorn, C. crus-galli. 



"Of the leaf impressions, one appeared to belong to a buttonwood, Platanus, the others to a willow, Salix, 

 — but they are too fragmentary to identify positively. 



"The wood and bark could not be well identified by their own characters, which are obscure, but tracing
