A GUIDE TO THE WILD FLOWERING PLANTS OF THE CHICAGO REGION, by 
Floyd A. Swink; Rockrose Press, Inc., 1225 W. Washington St., Chicago, 
Ill.; $3.00. 
Those of us who have struggled with limited success to identify plants 
by using the classical form of “key” as exemplified by Gray’s or even Brit- 
ton & Brown’s botanies, will hail with joy a key that can be used success- 
fully without a higher degree in botany, without a microscope and without 
picking the flower or digging up the root. The code key requires only six 
characteristics that are easily determined in the field; sometimes habitat 
must be considered. This is a new departure in keys and is applicable at 
least to this region. A separate key is used for the conifers. The grasses, 
sedges and rushes are not included, and the willows, hawthorns, dodders, 
goosefoots, etc. are not carried through to the ultimate species because of 
highly technical differences. About one thousand groups of plants are 
covered. There are twenty-four excellent drawings illustrating the different 
types of flowering and leafing. Everybody interested in the out-of-doors 
should have this book as a field companion. The author is associated with 
the department of Pharmacognosy and Pharmacology, College of Pharmacy, 
University of Illinois, in Chicago, and is well known as a leader of field 
trips for interested organizations.

X0UND RIveR, from the personal notes of Aldo Leopold. Oxford University 
Press, 114 Fifth Ave., New York 11, N.Y. $3.00. 
This is a compilation from the hitherto unpublished notes of Aldo Leo- 
pold, edited by Luna B. Leopold. It is a companion piece to “A Sand County 
Almanac,” which has delighted so many readers who appreciate the beauty 
of nature. While a number of the chapters are devoted to hunting, fishing 
and exploring, largely while in the U. S. Forest Service in his early life, 
even these writings are imbued with the vision of a poet. 
More serious chapters may be found in “Round River,” after which the 
book is named; these have the subtitle, “a parable.” Here is a description 
in poetry (though not in rhyme) of the interdependence of the soil and all 
living things, that could be written only by a master mind in conservation. 
This is further revealed in chapters entitled conservation and natural 
history, in which Leopold mentions the intimate study of a sparrow by an 
Ohio housewife, meaning of course our Mrs. Nice. 
In 1933 the University of Wisconsin created a chair of game manage- 
ment which was headed by Aldo Leopold. The line drawings by Charles W. 
Schwartz are excellent and in keeping with the style of the book.
