224 Rhodora [OCTOBER 
Similar divisions of North America into zones, sections, regions, 
districts, areas, formations, etc., occupy the greater part of the volume, 
and, though the reviewer would like to believe that the regions with 
which he is personally unfamiliar are better treated than the North- 
east, it is feared that only when the treatment is taken unaltered from 
the writings of some painstaking student will it prove to be anything 
but inaccurate. And what can be the character of the “ considera- 
tion” and statistics based upon such variegated data? Obviously, 
the less said the better. But the greatest pity is, that to the Old 
World botanist who is unfamiliar with North America and to the 
American botanist whose primary work is in other lines the book is 
apt to be judged, not by its disheartening array of inaccuracies and 
blunders, but by the fact that it is one of the volumes of Engler and 
Drude’s series, Die Vegetation der Erde; and any conclusions which 
may be innocently based by the unwary upon this “Survey” will 
always be open to doubt. 
Vol. 13, no. 153, including pages 189 to 208 and plate 92, was issued 
1 September, 1911.
