In all the four soils, the analyses of which are given above, the grains of quartz from the 
Calciferous sandstone and the Potsdam sandstone, are accompanied with scales of mica 
and grains of felspar. We did not search for potash, but it is probably present in a per¬ 
ceptible quantity. The magnesia is much less than in the soils of the Mohawk valley
