128 THE AMERICAN BOTANIST 



and like matters. All teachers who have anything to do with 

 the biological sciences will find this a most desirable book. It 

 is destined to give the teaching of nature study an impetus 

 toward sanity. It is published by D. Appleton & Co., New 

 York, 



For the past eight years, John P. Brown has been edit- 

 ing the journal Arboriculture in the interests of tree planting 

 and forestry in general, and the hardy catalpa in particular. 

 During this time he has had the satisfaction of seeing the ca- 

 talpa come to the front as a desirable tree for planting, and has 

 seen many millions of these trees set out by the railroads for 

 the production of poles and ties. With the October number 

 the magazine ceases publication. Evidently the catalpa can 

 now "go it alone." 



There are about a hundred woody plants growing in the 

 vicinity of San Antonio, Texas according to a little booklet 

 issued by Bernard Mackensen of the San Antonio High School 

 in which each species is discribed in untechnical language, its 

 time of flowering and fruiting noted, and all common names 

 cited. The southern affinities of the flora are seen in the in- 

 clusion of many names unfamiliar to botanizers in the Nor- 

 thern and Eastern states such as Ephedra, Cehatha, P^rosopis, 

 Sapindiis, Zizyphus and Cestrum. In genera like Querciis and 

 Celtis common to both regions the difference in floras is seen 

 in the fact that different species take the place of our common 

 forms. The booklet must be of special value to students of the 

 woody plants of southern Texas, but is of interest to all botan- 

 ists. Teachers in the schools of other parts of the country 

 could take an example from this book with profit.
