underlain by sand and gravel. The former of the two is a pallet

 locally. 



Brookfield, Madison Co. The Brookfield Brick Co. is the only 

 firm manufacturing brick at this locality 



Oneonta, Otsego Co. Two firms are manufacturing brick at 

 this locality, J. Denton & Son, and Crandall & Marble. The 

 works of this latter firm is situated on the Albany and Susque- 

 hanna Railroad near the village of Oneonta. Two kinds of clay 

 are used ; one of them from a bank five to 20 feet in thickness, 

 the other from a surface deposit three to five feet in depth. This 

 latter bed is underlain by sand. The product is consumed by the 

 local market. 



Goshen, Orange Co. P. Hayne has a clay deposit 55 feet deep, 

 underlain by black gravel. There is a slight stripping of sod. 

 Both drain tile and brick are made from the clay. 



Florida, Orange Co. W. H. Yernon's brick yard and clay 

 deposit are situated in the valley near the town. The clay bed is 

 10 feet thick, blue in color and tough. The upper three feet are 

 weathered to a red clay and make a better brick. The blue is 

 of sufficient purity for making pottery. Underneath the clay is 

 sand and hardpan. 



Oakland Valley, Sullivan Co. Mr. O. B. Wheeler of Middle- 

 town, N. Y., has an extensive clay deposit here. There are 

 about 125 acres of clay land lying between the Eavesink Eiver 

 and the "West Shore Railroad. The clay is found not only in the 

 valley but is also exposed in numerous cuttings on the hillside. 

 At the former spot a depth of 46 feet has been proven by boring 

 and at the latter 17 feet. In many places the clay crops out ; at 

 others it is covered by one to three feet of loam. An analysis of 

 the clay made by Prof. Draper of the New York City
