In all the four soils, the analyses of which arc given above, the grains of quartz from (he 

 Calciferous sandstone and the Potsdam sandstone, are accompanied with scales of mica 

 and grains of felspar. We did not search for potash, hut it is probably present in a per- 

 ceptible quantity. The magnesia is much less than in the soils of the Mohawk valley
