the sandstone, which usually forms a ridge on the surface, 

 be followed west from Linton's hill it will be found almost 

 barren ; and the same is true of its exposures east from its 

 outcrop at King's Mill. This sandstone exhibits a mingling 

 of some Chemung forms with others not described, the most 

 conspicuous of the former (though not yet found at King's 

 Mill) being Sp. disjimcta, Sby. 



A few miles southwest from the exposure just noted, this 

 sandstone is again seen, but not in place. Its characteristic 

 ridge and fossils are conspicuous near Shermansdale mills, 

 where, however, numerous species occur not found at King's 

 mill. The specimens also are in better condition, and many 

 belong to large species of Lamellibranchs. They are also 

 here exceedingly ferruginous, a mass of red, purple, or black 

 oxide of iron often occupying the places of the dissolved 

 shells. Want of time prevented my tracing this bed along 

 the southern outcrops of the syncline, but there can be lit- 

 tle doubt of its continuance. 



In the northern part of the county its outcrop is easily 

 found and traced. It constitutes in great part the axis of 

 western Middle ridge, and curves round the end of the Buf- 

 falo syncline, returning along the southern side of Hominy 

 ridge. It is conspicuous in Saville and Juniata townships 

 as mentioned in those reports. Fossils, however, are not 

 abundant, and I have seen in the northern syncline no such 

 evidence of abounding life as near King's mill and Sher- 

 mansdale. Fossils exist, however, and can be found in num- 

 bers amply sufficient for identification of the stratum. 



East of the Juniata the King's mill sandstone ranges 

 along Wild Cat valley from one river to another in two 

 nearly parallel outcrops. Here, too, its fossils, though 

 scarce, are not difficult to find. 



In Watts township also the line of outcrop continues, and 

 the sandstone here forms an almost continuous low stony 

 lid-.' along which its fossils, especially 8ch. rhombeus, may 

 be collected. 



From the above evidence the inference is just that the 

 King's mill sandstone extends over the whole of the Lower 

 Catskill area in the county, as a continuous bed, about
