Previous opinions concerning this locality—Formations occurring here—Their 
absolute and relative positions—Question of nonconformity between Lower - 
Upper Silurian—Notes on the accompanying map— Relations of Lower an 
Upper Silurian elsewhere. 
Strata of Lower and Upper Silurian date. e previous 
descriptions and figures of the mountain are collected in m 
and Hall was disposed to take this view. The figures given by 
Mather are very Seay and the one (Geol. N. Y. 1st Distr., pl. 
a fig. 6) showing a ote cross-section, seems to be gener- 
alized on a very theoretic basis. ‘ 
ing a rece recess in college work, I took opportunity . 
Visit this locality with a party of students, to see wey hicae the 
evidence might be in favor of one or the other of i fi de 
views, and in two days spent on the ground obtained the fo 
lowing results.
