128 Report on Building Stone of New York. 



length from north to south, and runs in a zigzag course, owing to the 

 rectangular joint walls. It has been worked back about 200 feet 

 from the road, in an easterly direction. At the top there is drift 

 earth and black slate, and the strata are found to increase in thick- 

 ness as the hill rises, going eastward. The slaty rock can be used 

 for common walls, but owing to a lack of demand, very little of it is 

 sold, and that at 25 cents per perch at the quarry. The succession 

 of strata here seen, is the same as in the other Hamburgh quarries, 

 as above described, and there is a remarkable uniformity and persis- 

 tence in the strata, as opened in the several quarries in the vicinity 

 of Union Springs. The thicker beds of the Smith quarry furnish 

 strong and durable stone for solid masonry. At present the product 

 is largely cut for construction of lock enlargement on the Erie canal, 

 between Rochester and Syracuse. Stone from this quarry was used 

 on the Vosburg tunnel of the Lehigh Valley railroad and in the via- 

 duct of the New York Central railroad at Rochester. The quarry 

 equipment includes six derricks. The stone is carted to the dock, 

 an eighth of a mile away, on the lake, and is shipped by boat over 

 the line of canal. 



The quarry industry at Union Springs has not grown, owing to 

 the many new localities which have been opened during the past 

 twenty to thirty years. The canal work has to some extent revived 

 the business. For solid masonry the stone is among the best. 



Auburn, Cayuga County. — The Upper Helderberg limestone 

 formation, which underlies Auburn and the adjacent country east and 

 west, has yielded a large amount of stone for building in the city ; 

 and its percentage of stone buildings is relatively high. The main 

 ledge on the eastern side of the city is continuous from the Osborne 

 works, to and beyond the Goodrich quarry. The old Garrett quarry 

 opened in 1810, is now covered in part, by the Osborne Reaper 

 Works. The present quarry of the Garrett Stone and Coal Com- 

 pany, is east of the old quarry site, in the face of the same ledge. 

 The strata dip gently to the south. The working is intermittent and 

 for local use mainly. Former years saw more work, and the product 

 went into buildings in the city, and to other points also. 



The Quarry of L. S. Goodrich & Son is east of York street, 

 and on the same ledge as that of the Garrett quarries. It follows the 

 line of the ledge, and runs in a north-westerly and south-easterly 

 direction for over 1,000 feet, and the face of the quarry fronts the
