Glacial scratches appear at the eastern end. The rest of the exposed 

 edge is old, roughened creek-bottom. Statistics regarding the foregoing 

 quarries will be found tabulated on a following page. 



The Stafford Limestone. This rock furnishes a stone of good quality 

 suitable for building or bridge work. It has been quarried in the bed of 

 Buffalo creek at the end of Winchester avenue, below Gardenville, and at 

 Lancaster. The only quarry from which stone has been taken during the 

 past year is that of George Bingham at the latter place. No record has been 

 kept of the quantity, which is not considerable. 



The Based Limestone. This stone has been quarried in a small way in 

 the creek below the dam at Blossom. It is used there for foundations and 

 to some extent in the abutments of the bridge across the creek. 



The Thermal Limestone. Since this limestone consists of one or two 

 thick layers of a durable stone it has been quarried for culverts and abut- 

 ments of bridges all along the outcrop. Owing to the limited quantity in 

 sight at any one place, the supply has been largely exhausted except in 

 ravines difficult of access. The only open quarry of consequence is in the 

 valley of Buffalo creek, between Elma and Marilla. The quantity quarried 

 here was not learned. 



The Portage Sandstones. Although, as has been elsewhere shown, 

 Portage bluestone of good quality is quarried in several places, no attempt 

 has been made to utilize it farther than to supply immediate local demands. 

 This is chiefly due to the fact, that Buffalo, the nearest market, is supplied 

 with durable stone from its own quarries, or gets it cheaply from a distance 

 by means of excellent lake and railroad facilities. In addition to the quarries 

 here tabulated, the following were noted which were either not in operation 

 or from which no statistics could be collected : 



Phelps, ....... 2 miles southwest of East Aurora. 



East of Griffins Mills. 



Joseph Myers, .... 2 miles east of Wales Center. 



Ulrich, li miles southwest of Wales. 



Charles M. Brayton, . . South Wales. 



Zeller, 4 miles north of Boston Centre. 



Pike and Townsend hills, . 3 miles southwest of Boston Corners. 



Daniel Sherman, .... 2 miles northeast of Collins.
