OTTAWA COUNTY. 235 



Michigan. It is found in the principal cities from Buffalo to Memphis, 

 and from Pittsburgh to Chicago. 



The facilities for lime-burning in the western part of the county can 

 not be surpassed. The stone, itself of the best quality, occurs in the 

 most favorable situations, both for purposes of quarrying and for cheap- 

 ness of shipment. These circumstances have made Genoa the greatest 

 lime-shipping point on the Lake Shore and Michigan Southern Railroad, 

 the aggregate being, for the year 1870, nearly twelve thousand tons. The 

 lime, especially that which is burnt from the Niagara formation, is a 

 pure white, yet that from the Waterlime can not, by the eye alone, be 

 distinguished from it. The two are sold in the market indiscriminately, 

 bringing the same price. It is believed, however, that the Niagara will 

 differ from the Waterlime in being more cheaply and quickly burned, 

 will weigh less, bulk for bulk, will be a little whiter, will slack quicker 

 and with greater evolution of heat, and will set sooner. The Waterlime 

 is more dense, has a slight hydraulic quality — at least in many places — 

 will not crack after once setting in the wall, and for plasterers' use will 

 be preferable in applying hard-finish, since it will afford ample time for 

 polishing and rubbing down. 



The only brick-yard within the county, so far as known, is that owned 

 by Henry Moser, at Elmore.
