what to spray for, what to spray with, and when to do it. To spray a 

 tree without any definite object is like giving a man .physic without 

 knowing what is the matter with him, or whether anything is the matter 

 at all ; " and on page 14 they say : " Above all it should be remembered 

 that it is a mere waste of money to spray, unless the spraying is done 

 thoroughly." A chapter is devoted to " appliances and the work that they 

 are intended to perform ; " this is followed by descriptions of the various 

 materials used for making spray washes, and twenty-eight recipes are given 

 for their manufacture. Persons who use a large amount of fungicides and 

 insecticides are recommended to make up their own washes, but " with 

 smaller growers and gardeners it is otherwise, and the difference in the cost 

 of buying or of making up the insecticides would be counterbalanced 

 by the probable superiority of these substances when made by the skilled 

 chemical manufacturer." This chapter is followed by one on pests ; 

 they are mentioned under the names of the trees or plants (which are 

 arranged alphabetically) that they usually attack. The remedies and the 

 time for their application for each pest are given. A spraying calendar, 

 which should prove of great service to fruit growers, is given at the 

 end of the book. On page 110 is a most useful table showing the 

 amounts of the ingredients which are required to make 1, 10, or 

 100 gallons of wash and their percentages of strength. This table will 

 prove of the greatest assistance when compounding a different quantity 

 of wash from that given in the recipe. We can most confidently 

 recommend this little book to the attention of all fruit growers ; its 

 price places it within the reach of everyone who cultivates fruit. 



" Handbook of Hardy Trees and Shrubs." By George Bunyard, 

 V.M.H. 8vo., 160 pp. (Bunyard, Maidstone, 1908.) 3s. 6d. net. 



This book can only be described as an extended nurseryman's catalogue. 

 It unfortunately omits much that might usefully have been included. In 

 the first place, there is little to guide the planter of trees and shrubs, 

 the descriptions of the latter being sadly inadequate, while the practical 

 operations are very cursorily passed over, and throughout the whole 

 book, orthography in particular has received little attention at the haTids 

 of the reader. Thus Eucryplvia and Choisya are both wrongly spelt at 

 page 113, while on the plate, opposite the same page Carpenteria is 

 incorrectly rendered. The rendering of Weigelia on the plate opposite 

 page 92 is incorrect, as is also Aticuparia (page 19), Olearia (page 130), 

 Hamamelis (page 81), Euonymus, and hosts of others. 



There are a number of illustrations, and useful lists of trees and 

 shrubs for various soils and positions are given at the end of the work. 



" Timber." By J. R. Baterden, Assoc. M.Inst.C.E. 8vo., .351 pp. 

 (Constable, London, 1908.) 6s. net. 



This is probably the most exhaustive and reliable of the few works 

 that have been written on the subject of timber ; indeed a vast amount of 

 useful information has been crammed into some 350 pages. The illustra- 

 tions, too, are good, and assist in many cases in explaining the text, while 

 the tables have been compiled with care, and are no mere lists of dry 

 figures.
