For the past three years no cut stone has been furnished 

 by this quarry. In 1898 the total output was valued at about 

 $1300, and was mostly used for foundations and backing. For 

 this material fl.oO a cubic yard is obtained. Expense of lifting,, 

 handling and transportation prevents competition, even locally 

 with the New England and Hudson river stones. The quarry 

 will probably soon be abandoned because of the poorness of 

 east and west walls, and because adjoining lots have been sold 

 for building. Mr Nichols then expects to commence quarrying 

 on his own land, a little farther north on the same ridge. 



Uniontown, Westchester co. A quarry (10) here was worked 

 for a time in order to get rough stone backing for one of the 

 Warburton avenue bridges. The opening is in a light colored 

 (gray) gneiss, with several pink seams. The mass of the rock^ 

 however, shows little or no injection. Strike and dip n. 25° e., 

 56° e. The product shows too much contortion in the layers to 

 permit the quarry, if ever reopened, to become a serious com- 

 petitor of Lefurgy's. 



Bryn Mawr, Westchester co. Along Palmer avenue, west of 

 Bryn Mawr, near Fort Field reservoir, two small openings (12) 

 have been made in Fordham gneiss. The easternmost is in a 

 rather poor grade Fordham, minutely crumpled and breaking 

 into tabular pieces. The westerly opening is in better rock, and 

 supplied part of the stone for the reservoir walls and gatehouse. 

 Both openings were worked later to supply macadam for Palmer 

 avenue. PL 10 shows a face of the Fordham gneiss exposed in 

 excavating for Fort Field reservoir, and pi. 47 the gatehouse, 

 built from good specimens of this gneiss. 



Lowerre, Westchester co. In Lowerre small quarries (11) were 

 opened in 1898. The rock was a rather poor Fordham gneiss, 

 with granite injections along certain bedding planes and a peg- 

 matitic dike crossing the bedding. The total product to May 1, 

 1899, was about 2000 loads. Rough stone brought Toe to 85c a 

 load, while larger stone, roughly trimmed, was worth |1.50. The 

 materiaj was used for foundations, etc. Four men were em- 

 ployed. This stone was badly jointed, and could be handled
