QUARRY MATERIALS OF NEW YORK 75 



with black, and the latter a uniform pink tint in which there is 

 little but the coloration of the feldspar noticeable. The pink granite 

 finds special favor for monumental purposes. 



The company has two quarries in operation, of which the more 

 northerly has been mainly worked and has yielded most of the stone 

 of medium grain. The face here is about 300 feet long and 75 feet 

 high. The vertical joints are rather widely spaced and run N. 45 E. 

 and N. 35 ° W. The bed joints dip into the hill at an angle of 15 or 

 more, causing some difficulty in loosening the blocks. Material of 

 any size can be obtained. A small dressing and polishing works 

 have been provided for turning out finished material. The granite 

 had a well-marked rift and grain, so that excellent paving blocks 

 can be obtained from the waste, but this product yields little profit at 

 present owing to the competition which has arisen from the quarries 

 in the south with their cheaper labor. 



The more southerly quarry is in process of development. It has 

 a face about 150 feet long and 50 feet high with a slope which will 

 afford 25 feet or more additional height. The principal product is 

 pink granite, though there is some red, medium-grained granite 

 associated with it. About 10 or 15 feet of the surface rock is dis- 

 colored by sap and has to be stripped before marketable material 

 is obtained. The jointing here is irregular, with no predominant 

 directions noticeable. 



A third quarry is situated between the others, but was not worked 

 at the time of inspection. 



The company has a very complete equipment and can furnish 

 rough and cut stone in almost any size and quantity. Some of the 

 structures for which this stone has been used include the new por- 

 tion of the American Museum of Natural History in New York, 

 the National Bank Building in Clayton and the Maryland Museum 

 Building in Baltimore (polished columns). The red granite suitable 

 for polishing brings about $1.25 a cubic foot and the pink granite 

 from $2 to $3 a cubic foot. 



General observations. The color effect of the red granite is 

 very similar to that of the Grindstone Island granite. The polished 

 surface is bright red. The rock face and hammered surfaces are 

 lighter than the polished and give a pleasing warm tone when seen 

 in structures. The contrast between hammered and polished work, 

 as exhibited in monuments, is marked. 



The pink granite is considerably lighter than the red and, owing 

 to its fine texture, appears to be of almost uniform body. When
