The other brick yard at Saratoga is owned by Mr. D. Davidson. 

 It is situated at the outskirts of the town, just west of Judge 

 Hilton's yard. The clay bank, which is about 28 feet thick, is 

 about 150 feet from the yard; it is stratified, the layers being 

 from one to eight inches thick and separated by thin laminae of 

 sand. The clay is of a light brown color, being underlain by 

 calciferous limestone and overlain by a foot of soil. Mr. David- 

 son has 22 acres of clay land. Tempering is done in ring pits 

 and the clay is molded in a soft mud machine. Drying is done 

 in an open yard, and burning in scove kilns. The fuel used is 

 hard wood. 



Hoosick Falls, Rensselaer Co. John Dolin's clay bank is about 

 40 feet high and has an extent of six acres. It is used for making 

 building brick. The product is consumed in the vicinity. 



Middle Granville, Washington Co. J. H. Pepper is the only 

 manufacturer at this locality. His clay bank is 45 feet high, and 

 2000 feet long. The clay is blue, and scattered through it are 

 some streaks of sand. A bed of gray sand 20 feet in thickness 

 underlies the clay and is in turn underlain by slate. 



Plattshurg, Clinton Co. There are several yards here. That 

 of J. Ouimet lies at the north end of the town. It is an open 

 yard and the bricks are made by hand power. The clay which is 

 hard and tough is of a yellowish brown and red color and is 

 mined with plows. 



Charles Yaughn's yard is similar to the preceding, and is at the 

 south end of the town. The clay is 20 feet thick. 



Gilliland and Day's yard is situated on Indian Bay, six miles 

 south of Plattsburg. The bricks are also molded by hand power. 

 All these yards sell most of their brick at Plattsburg.
