stratified. It is worked by picks and carted down to the yards. 

 Tlie bank which is 30 feet in hight is located on the hillside some 

 500 feet east of the yard. It is probably underlain by the sand 

 and gravel which crops out in the terrace escarpment behind the 

 yard, and which is used for tempering. 



Coxsackie, Greene co. There is only one yard here, that of 

 r, W. JSToble. It is situated at an elevation of 100 feet above the 

 river, and about a quarter of a mile north of the village. The 

 clay bank adjoins the yard and is 35 feet high. Both blue and 

 yellow clay are used. Shale underlies it. The clay is quite dry and 

 is broken up by undermining. Soak pits are used for tempering. 

 There is an exposure of blue clay in the terrace escarpment south of 

 Coxsackie. 



Athens, Greene co. Of the three yards at this locality, situ- 

 ated about half a mile north of the village and adjoining each 

 other, only two are running. The most southern one is that of 

 William Ryder, situated 80 feet above tide level and about 500 

 feet from the river. Mr Ryder owns 12 acres of clay land. The 

 clay, which has not been excavated below the level of the yard, runs 

 up to 125 feet above mean tide, and is both blue and yellow with 

 about 6 feet of loam covering. A well was sunk 18 feet below 

 the level of the yard, without reaching the bottom of the clay. 

 The clay is mined by plows and scrapers. The upper 6 feet of loam 

 is mixed with the clay. The bricks when taken from the kilns are 

 sent on cars down to the shore, where they are loaded on barges 

 for shipment to JSTew York city. Adjoining this yard on the north 

 is that of Mr. Porter, not worked. A few hundred feet north of 

 this, on the south side of Murder creek, is the yard of I. R. Porter. 

 Though the yard is situated near the shore, the water is not deep 

 enough for the brick barges, and the bricks have to be carted some 

 200 yards to the dock. The clay bank adjoins the yards and is 

 mined by plows and scrapers. Horse power machines are used. 



Coeymans Landing, Albany co. There are two brick yards at 

 this town; they lie north of the town along the river shore and
