Here the paleontologist can find specimens to his heart’s 
content. Every stratum, with the exception of one fine 
grained sandstone, is literally filled with fossils. Further- 
more, our share of this group is very extensive. It cov- 
ers the greater part of the towns of Pompey, Lafayette and 
Otisco, and no small part of Onondaga, Marcellus, Fabius, 
Tully, Spafford and Skaneateles. Another favorable cir- 
cumstance connected with this group is that in the towns 
just mentioned we find many small ravines and gorges. 
These cut through the hillsides, which are largely com- 
posed of Hamilton rock, and run down to meet, at right 
angles, the longitudinal north and south valleys into which 
the county is divided. These ravines furnish excellent 
places for studying the stratagraphical and paleontological 
characteristics of this group. Still another favorable cir- 
cumstance is that the rocks are so arranged, the harder 
shales and sandstones overlying the softer shales, and all 
in turn being overlaid by the Tully Limestone, that we 
have just the conditions necessary for the formation of 
waterfalls. Consequently, we will find numerous beauti- 
ful falls throughout this part of our trip. 
As afew of the inviting places, we mention the steep 
ravines near Amber and South Onondaga, together with 
numerous others in Tully, Otisco and Spafford. As afew 
of the best falls for practical study we mention Pratt’s 
Falls, Pompey, where there is a fall of water claimed to be 
166 feet in height; Buhr’s Falls, Delphi, 64 feet; Tinker’s 
Falls, 60 feet; and Gamble’s Falls. The rocky shores of 
Skaneateles Lake, and the numberless gullies and ravines 
leading down to them, furnish still other advantageous 
places for the study of this group. In the ancient coral 
reef at Staghorn Point we have an excellent place for 
studying corals. ‘There are fifteen species of cyathaphyl- 
loid corals found here, together with numerous species of 
other families. This one case will serve as an example of
