CLAYS OF NEW YORK 697 



Bros.' yard, where a well was sunk 65 feet through, the clay, which, 

 added to the hight of the bank (65 feet), gives us a total thick- 

 ness of 130 feet at this point. The clay is usually covered by 

 gravel, and by sand in some cases sufficiently fine to be used for 

 tempering or even molding. It is worked in benches, and the haul- 

 age distance is 200 to 300 feet. ■ At Timoney's clay bank there is 

 some extra labor in stripping the scrub oaks and other bushes which 

 cover the surface of the terrace. 



Fislikill, Dutchess co. Harris & Ginley's yard is situated about 

 one quarter of a mile below the town. The clay bank is leased 

 from the ISTew England railroad co. It was formerly quite thick, 

 but clay having been dug for 50 years but a small portion of the 

 bank remains. The clay has a maximum thickness of 45 feet. 

 Streaks of quicksand occur throughout the clay; it is underlain by 

 hardpan and shale. 



The other yards at this locality are situated along the river from 

 a point about half a mile above Tishkill up to Low Point station. 

 One of the yards is just north of Low Point. The most southern 

 one is that of Aldridge & Sherman, with 600 feet water front. 

 The clay land of these two firms belongs to the W. E. Verplanck 

 estate. ISText on the north are works of the Brockway brick co., 

 with 1200 feet of water front. This firm owns its clay bank. The 

 bricks are dried on pallets. The next two yards belonging to 

 Lahey Bros., (650 feet water front) and Dinan & Butler (475 feet 

 water front), respectively, lease their clay bank from the W. E. 

 Verplanck estate." Dinan & Butler have a pallet yard. The five 

 above-named firms obtain their clay just east of the yards from 

 the escarpment of a 90 foot terrace; it is both blue and yellow and 

 overlain by 4 to 6 feet of loam, sand and gravel. A short distance 

 north of Dinan & Butler's yard is that of J. V. Meade. About 20 

 feet of clay are exposed in the bank, which adjoins the yard. The 

 clay is overlain by 4 to 6 feet of sand and cobblestones. The sand 

 is screened and used for tempering.
