The Passage of Granite Rock into Fertile Soil

Abstract

HAVING for the last three or four years paid particular attention to the natural formation of soil, I venture to believe that a concise account, or rather summing up, of the results of my researches, and of the mass of my observations—in one typical direction—may be of interest to the readers of NATURE. AS indicated in the heading, the making of soil from granite is the only section of a very large subject which will be briefly considered in this paper.
