BOOK REVIEWS. 
admirably done, well maintaining its reputation not only for excellence of 
matter, but for clearness, sound practice, good printing, and capital index, 
" Cultivation with Movable Frames." By Herbert Cowley. 32 pp. 
(Country Life, London, 1920.) gd. net. 
A very little booklet that will easily go in one's pocket, and that will fill a 
useful want for cottagers, small holders, and others with a limited income who 
are anxious to get all the produce they can without very much outlay. An 
excellent calendar of work for each month is given, the whole being well printed 
and indexed. 
" Productive Small Fruit Culture." By F. C. Sears, M.S. 8vo. 368 pp. 
(Lippincott, Philadelphia and London, 1920.) los. 6d. net. 
This book was written principally for American readers, and some of the 
matter, such as grape-growing in the open, would be valueless for British readers ; 
but apart from that, there is a vast amount of really good information that is 
valuable to the British fruit-grower and which he will be wise to read and study 
carefully. Not only is one told in the best and most attractive manner how to 
produce the heaviest and best crops, but the best system of manuring is specially 
dealt with, and the various fungus and insect pests are treated in a masterly 
style, and yet in such a simple way as will be quickly and easily understood. 
f " The Rock-Garden." By E. H. Jenkins. 8vo. 128 pp. (Country Life, 
London, 1920.) ys. 6d. net. 
We believe an early edition was first published as " The Small Rock-Garden " 
in 1913, and this is a new edition revised, enlarged, and brought up to date. 
This book is especially welcome in these days, as few can afford the 
labour, expense of fuel. Sec, of maintaining glass erections, and fall back on the 
more natural conditions supplied by outdoor gardening in the form of rock- 
gardens, including moraines, water-gardens, and bog-gardens. On all sides we 
find that this fascinating style of gardening is much in evidence, and all who 
have an idea of adopting it should read Mr. Jenkins' book, which is full of interest, 
sound advice and clear instruction, beautifully illustrated and well printed. 
" The Perpetual Carnation." Illustrated. By Laurence J. Cook. 8vo. 
108 pp. (" Country Life," London, 1920.) 25. 6d. net. 
In this latest edition Mr, Cook has not only retained all the essential features 
of the former popular editions, but has brought all the matter up to date in his 
pleasing and instructive manner. We can heartily commend this book to all 
who cultivate this favourite flower. 
" Profitable Fruit- Growing," By John Wright, V,M,H. 8vo. 132 pp. 
(CoUingridge, London, 1920.) 2s. net. 
The mere fact that this first-rate book has run into the eleventh edition is 
excellent proof of how much read and popular it is amongst all fruit-growers in 
a large or small way. The present edition has been revised and brought up to 
date by the late author's son Walter, and, needless to state, in such able hands 
it has been well done, 
" A Course of Practical Chemistry for Agricultural Students." Volume I. 
By L, F, Newman and H, A. D. Neville. Demy 8vo, 235 pp, (The University 
Press, Cambridge, 1920.) los, 6d. net. 
The first part of Volume II. of this Course has already received our notice 
(R.H.S. Journal, XLV. p. 379). The book now under review covers the first 
year's course on the chemistry and physics of the soil, and on the whole it 
presents the subject in a successful and attractive fashion. It is designed for 
the use of students having no previous knowledge of chemistry or physics and 
therefore it is inevitable that the treatment of these subjects in so small a volume 
must be rather condensed and eclectic, but admitting this limitation it must 
be stated that the subject-matter is well arranged and lucidly explained. Our 
quarrel, if any, must be, not with the authors, but with the University of Cam- 
bridge, that apparently demands so scanty a groundwork in natural science from 
candidates for its Degree in Agricultural Science. 
The book is well printed and practically free from typographical errors. 
Of its 235 pages, 102 are blank for students' notes. That so small an amount of 
letterpress should bring the price of. the book to half-a-guinea is an indication 
of the lamentably increased cost of book-production, or of the opulence of the 
Cambridge undergraduate.
