 One half mile beyond the above station on the farm of Mr Tarr, 

 there are a number of large boulders from which corals may be 

 obtained in abundance. 



1 Acervularia ? inequalis Hall 



2 Diplophyllum coralliferum Hall 



3 Halysites catenulatus Linn. 



4 Favosites niagarensis ? Hall 



5 Stromatopora concentrica Hall 



6 S. constellata Hall

From this point the Cobleskill is covered by drift for more than 

 a mile, but it again is exposed by the roadside and on the farm at 

 Eugene Maxwell's, and from here exposures are frequent on the 

 way to Grovenor's Corners, where the Salina is also exposed. 

 All these outcrops of the Cobleskill are fossiliferous, and the col- 

 lections contain all the common forms and several specimens of 

 a species of Dalmanites. The Cobleskill is readily traced from 

 Grovenor's Corners to Carlisle, and at a distance of y 2 mile 

 northwest of the village it has been quarried for inclosure walls. 

 The Salina shales crop out by the roadside a short distance 

 beyond. 



Species as follows were collected from the quarry. 



1 Chaetetes sp. 



2 Enterolasma caliculus Hall 



3 Favosites niagarensis? Hall
