or price of this class of stone is not sufficient to give a decided 

 advantage to any one quarry. Seely's quarry, at Scarsdale, is 

 handicapped by greater distance from market, as little building 

 is going on near it. Lowerre and Park Hill use a considerable 

 quantity of this class of stone. A certain quantity of cut stone, 

 about 2 feet by 2 feet by 18 inches in size, is used for private 

 houses and for walls. This item is, however, of little 

 importance. 



The chief profit of the quarries comes from stone supplied to 

 public buildings, schools, etc., for which a high grade of cut 

 stone is required. Occasionally large semipublic buildings — • 

 hospitals, libraries, etc. — are erected, and to supply stone for 

 these is almost as profitable. 



As good trap and limestone can be obtained cheaply from 

 the Palisades and Tomkins Cove, little stone is furnished by 

 the local quarries for macadamizing. Occasionally, however, 

 the Yonkers gneiss is used for this purpose on second class 

 roads. The stone is then handbroken at the quarry, unless the 

 buyer owns a crusher. Almost all of the so-called macadam 

 Toads are in reality telford roads, having a subpavement of 

 large (5 to 8 inches) stone. The local quarries furnish most of 

 this telford, using for it their worst grade, the coarse red 

 Yonkers gneiss. 



Scarsdale, Westchester co. Seelifs quarry (19). Owned and 

 operated by H. S. Seely. Several openings on the north side 

 of Piatt avenue, about half a mile west of Scarsdale station. 

 The opening now worked is on the extreme west of the group, 

 and has been worked for 100 feet along the strike. It is 30 feet 

 wide and 10 to 20 feet deep, being entirely below the general 

 ground level. A larger opening, on the extreme east of the 

 group, shows an 8 foot bedded dike of a coarse-grained horn- 

 blende-feldspar rock. The average quality however, is very 

 high; a large percentage of the material being the blue Yonkers. 

 No machinery is on the ground, save one derrick — horse power. 

 The product has, for five years or more, been only foundation 

 stone. It will not exceed 150 cubic yards annually for which
