BRTCK YARDS 207 



crushed in a dry pan and then molded in a dry clay machine ; 

 drying is done in tunnels and burning in stationary up-draft. 



Spring Brook, Erie Co. There are extensive deposits of clay 

 and shale at Spring Brook, on the land of E. B. Northrup, but 

 they are not being worked. 



JEvans, Erie Co. Wm. Bolton has a horse-power yard here. 

 The clay is a local deposit, chiefly blue in color, and the lower 

 portions are stratified. It is underlain by sand and hardpan. 

 The yard is run in accordance with the local demand 

 for brick. 



DnnJcirTc, Chautauqua Co. Wm. Hilton's yard is situated in 

 the valley, about one mile west of the town. The clay deposit 

 is about 20 feet thick, and is underlain by rock. The upper six 

 feet are yellow and below this is blue. Stones are found scat- 

 tered through the clay and have to be separated. The yellow 

 clay gives a better colored brick, while the blue clay shrinks 

 more, but is said to give a harder product. The blue clay 

 obtained from the main clay bank has to be tempered with sand ; 

 it has not been much used up to the present, however. Rolls 

 are used to crush the stones and the clay is tempered in a pug 

 mill. Mr. Hilton uses a soft mud machine of his own manu- 

 facture. The brick are dried on pallets, and the burning, Avhich 

 takes eight to 11 days, is done in scove kilns. Coke is used for 

 watersmoking and coal for subsequent firing. Most of the 

 brick are used in the vicinity. 



Jamestoivn, Chautauqua Co. Two yards are in operation 

 four miles east of this locality. Those of C. A. Morley and M. 

 J. Mecusker & Son, They are about four miles east of James- 

 town. The two yards adjoin each other, and the deposit of clay 

 worked by them is of considerable size. In addition to brick, 

 Mecusker & Son make drain tile and hollow brick. The clay 

 deposit is basin-shaped. A boring near the water works showed :
