The paper before the Academy consisted in a verbal communication of the salient features of the forest vegetation. It was afterward written out in full and sent to Garden and Forest (See Vol. IV. pp. 460, 472 and 531). As the paper may be of general interest to Iowa readers I give it essentially as it appeared in Garden and Forest. A few notes have been added.
