botanist, and to the catholic lover of plants though he be no botanist. This is 

 not the place to attempt a critical review of this scholarly book; but we most 

 cordially recommend it to the serious notice of all seekers after knowledge of 

 the flora of the ancient world and its relation with the plants of the present. 



"Flowering Trees and Shrubs for Use in South Africa." By T. R. Sim. 

 8vo. 200 pp. (Specialty Press, Johannesburg, 1919.) 75. 6d. 



With the growth of permanent settlements in South Africa the making of 

 gardens is bound to advance, and we have in this annotated list one of the first 

 attempts at a guide for the planter of trees and shrubs under South African con- 

 ditions. Lists for various purposes are given in alphabetical order, and each 

 plant is described with reference to a figure. Many are figured either by a drawing 

 or by a photograph in the present work. 



" Butterfly and Moth Collecting." By A. E. Hodge. 8vo. 128 pp. ; 18 figs. 

 4 plates. (Pearson, London, 1919.) 2s. 6d. net. 



This little book is intended as a young collector's guide to a fascinating 

 hobby, and to supply a want in this subject, the alternative being to wade 

 through scientific treatises which often tend quickly to damp the ardour of the 

 amateur. 



It is a pleasantly written and well worked -out book, dealing with every 

 branch of the subject — equipment, how and what to collect, breeding in cap- 

 tivity, mounting, &c. In the Appendix is given a unique but unscientific key 

 to the British butterflies, based upon size, outline of wings, and ground colour. 



" Peach-Growing." By H. P. Gould. 8vo. 426 pp. (Macmillan, New 

 York and London, 1918.) 10s. 6d. net. 



To all peach-growers this book will be of great interest, although written for 

 American readers, for it covers many sides. In America, where peach-growing 

 is such an important industry, the varieties are grouped in sections in a most 

 methodical style of classification, viz.: 



Peen-io Race. — This race traces its origin to an importation of seed from 

 Australia, made in 1869 by the late P. J. Berckmann, of Augusta, Georgia. From 

 this collection of seed came a peach quite distinct from the others, and this 

 Peen-to race is of special value in Florida and the Gulf Coast region. 



South China Race. — This type originated in seed from China. One being 

 specially good was named the ' Honey variety,' and was introduced about 1855 

 by Charles Downing, of New York, and like the Peen-to race it succeeds best in 

 the warmer parts of America. 



Spanish Race. — This race was introduced into Mexico from Spain by Catholic 

 missionaries nearly 300 years ago, and apparently there are many varieties. It, 

 like the other races named, seems to answer best in Texas and the Gulf States. 



North China Cling Race. — This type was introduced by the late Charles 

 Downing through Mr. Winchester, the British Consul at Shanghai, in 1850. 

 This race seems to have very large fruit, and to be an important and popular 

 type, hardier than some of the other races. 



Persian Race. — It appears that this was imported from Persia to Italy about 

 1 550, and to America about 1680. Many of the varieties grown in Britain belong 

 to this group, and in America they are appreciated for their hardiness and 

 good constitution. These different groups or races are distinguished by the 

 forms of the stones or seeds, and will interest the British pomologist. 



" Vegetable Forcing." By Ralph L. Watts. 8vo. 431 pp. (Orange 

 Judd Co., New York, 1917.) 2$. 



This treatise was written for American readers, and will no doubt be valuable 

 to them, but for British growers its chief merits will be the valuable instructions 

 on how to deal with insect and fungus pests. These seem very practical and 

 up to date. The American winters are on the whole more severe than we have 

 here, which makes a considerable difference in practice. At the same time, 

 anyone commencing this enterprise here would gain much useful information 

 from its admirably printed, well-written, and illustrated pages, that finish with 

 an excellent index. 



" The Principles and Practice of Pruning." By M. G. Kains. 8vo. 420 pp. 

 (Orange Judd Co., New York, 1917.) 2$. 



We have read a number of books on American systems of pruning, &c, but 

 we do not remember one so interesting or so clearly expressed as this, which is
