NIAGARA LIMESTONE. 353 



rock. It is admirably adapted to use as dimension stone of various 

 kinds, particularly for trimmings with white brick, with which its 

 color harmonizes beautifully. 



A white and most excellent rock of similar texture is wrought at 



o 



Johnson's quarry, Genesee, and is worthy of high commendation. 



Near Cedarburg, at the quarry of Messrs. Schleifer & Anshuetz, a 

 white, granular, crystalline rock occurs in massive deposit without ev- 

 ident bedding joints, so that blocks of any required dimensions can be 

 obtained. It cuts with great facility and is a beautiful stone. Large 

 quantities are shipped to Milwaukee, and the surrounding country. 



At Kuntz' quarry, Manitowoc, a compact, fine-grained, crystalline 

 dolomite of excellent quality has been mined to some exent, and even 

 sawed and polished as a marble. While not suited to polishing, it is 

 excellent for the coarser, ornamental purposes. In Cooperstown and 

 elsewhere very fine dolomites await development. 



Gen. Q. A. Gilmore, in his work on Building Stone, gives the 

 crushing strength of a two inch cube of bluish drab limestone, from 

 Sturgeon Bay, as 86,000 pounds on bed, and 66,750 on edge, with the 

 comment, " a remarkably solid, stable stone." That of the white Jol- 

 iet (111.) limestone, sometimes imported, he gives as ranging from 

 45,000 to 67,000 on bed. In addition to the fine qualities of rock, the 

 formation furnishes unlimited quantities of material suitable for 

 rough-dressed, course work, and the heavier class of masonry. 



Flux. The limestone from Schoomaker's quarry, west of Milwau- 

 kee, is used successfully as a flux in the Bay Yiew Iron Works, and 

 the limestones from Trimbone's and Druecker's quarries have been 

 also tested with favorable results. The pure, granular limestones in. 

 the towns of Cedarburg, Graf ton and Germantown, may also be recom- 

 mended.
