Commercial fertilizers and poisonous insecticides in 1907-8, G. S. Fraps 

 (Texas Sta. Bui. 107, pp. 5-16). — Analyses and valuations of fertilizers ex-

AGRICULTURAL BOTANY. 



Mushrooms, edible and otherwise, M. E. Hard (Columbus, Ohio, 1908, pp. 

 XII +609, figs. 504). — This is a popular guide to the study of mushrooms, about 

 800 species being described and many illustrated by half-tone prints. The aim 

 of the author in preparing this book has been " to describe the species, as far as 

 possible, in terms that will be readily understood by the general reader ; and 

 it is hoped that the large number of illustrations will make the book helpful 

 to those who are anxious to become acquainted with a part of botany so little 

 studied in our schools and colleges." 



Notes are given regarding the habitat and time of growth of the different 

 species and also on their edibility. Chapters are included giving directions for 

 cooking mushrooms and on how to grow them. 



The yeast fungi, F. G. Kohl (Die Hefepilze. Leipsic, 1908, pp. VIII+3-'f3, 

 pis. 8, figs. 59). — This is a study on the organization, physiology, biology, syste- 

 matic classification, importance, and bearing on fermentation of yeasts and 

 yeast-like fungi. Among the yeast-like fungi, the author includes the Schizo- 

 saccharomycetes and such genera of fungi as Torula, Mycoderma, Monilia. 

 Oidium, Dematium, etc. 



Acclimatization of plants, H. F. Macmillan (Circs, and Agr. Jour. Roy. Bot. 

 Gard. Ceylon, Jf (1908), No. 9, pp. 55-73). — In a paper read before the Ceylon 

 Agricultural Society, the author gives an account of what has been done in 

 Ceylon in the acclimatization of plants, and calls attention to the necessity for 

 care in the introduction of plants, as it is usually the most worthless ones that 

 are generally most readily acclimatized. Lists are given of plants which have 

 been introduced into Ceylon from other parts of the world, showing the dates 

 of introduction, so far as known, and the elevation or district best suited to 

 their growth. 



On the effect of a partial removal of roots and leaves upon the development 

 of flowers, M. Shiga (Jow. Col. 8ei.. Imp. Univ. Tokyo, 23 (1907). Art. Jf. 

 pp. 15). — The author carried on a series of experiments with peas of different 

 kinds, horse beans, Japanese morning glories and buckwheat in water and pot 

 cultures to determine whether a partial removal of leaves, roots, etc., has 

 any effect upon the formation of flowers. 



When the main root and most of the lateral roots were removed, flowering 

 was promoted, except with buckwheat. When all the lateral roots were
