Pottery industry 



One pottery is owned by John Schmidt. The shop is located 

 at 166 Scio street, Rochester. The bulk of the material used is 

 Quaternary clay obtained in the town of Chili, at a point (4) 4 

 miles south of the center of Rochester, between the Scottsville 

 road and the Western New York & Pennsylvania Railroad. In 

 addition to this, clays from New Jersey and Ohio are used for 

 glazes. The product consists of flowerpots, some of which are 

 glazed by slipping. The large pots are made on a potters' wheel, 

 the small, in presses with changeable dies. One kiln is used. 

 Four men are employed. 



Sewer pipe industry 



There are two sewer pipe manufactories in the county, both 

 located at Rochester. The New York Sewer Pipe Co., (office in 

 German Insurance building, Rochester) disposes of the entire 

 output. The factory of the Rochester Sewer Pipe Co. is located 

 at 545 Oak street, and the office is at 247 Powers building. The 

 president and general manager is R. H. Gorsline; director, 

 W. H. Gorsline. Most of the clay used in this factory comes 

 from the town of Chili, 1 mile south of Maplewood station^. 

 With this is used a New Jersey fire clay from Raritan river 

 (Cretaceous), as the Chili clay will not stand vitrifying alone. 



The Chili clay is yellow or limonitic, averaging 3 feet in 

 depth, and is underlain by quicksand. In some parts of the 

 bank the clay becomes sandy, too sandy for use, 10$ to 15$ 

 being the limit at which it can be used. When sand is needed, 

 it is obtained in stripping this bank. The material is brought 

 to the works' on the Buffalo, Rochester & Pittsburg Railroad. 

 At the bank the cars are run in on a siding, and the clay is 

 thrown in from the spade. The New Jersey clay is shipped by 

 boat on the Erie canal. Thirty boat loads, or 5000 tons of this 

 clay and 8000 tons of the Chili clay, it is stated, were used last 

 year. 



The process of manufacture of sewer pipe is as follows. The 

 clay, roughly proportioned by wheelbarrowfuls, is dumped into
