98 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. 
In his short chapter on diseases, Mr. Elliott professes to have found a cure 
for the disease sometimes called crown canker, which has become very destruc- 
tive in many gardens. He paints the stems, not the leaves, with dilute sulphuric 
acid (two tablespoons to a gallon of water), or with dilute permanganate of 
potash. This should be good news for many rosarians the world over. 
Mr. Elliott's book is pleasantly written and well printed, and will repay 
perusal by rose-growers in this country, who will find that, generally, the roses 
that succeed in this country are also popular in Australia. 
" Chemistry of Crop Production." By T. B. Wood. Cr. 8vo. 199 pp. 
(Clive, London, 1920 ) 7s. 6d. 
This is an eminently readable little book dealing clearly with the main factors 
of plant -growing, so far as water supply and supplies of chemical substances — such 
as lime, potash, nitrogen, and phosphates — go. The text is illustrated by some 
excellent maps ; and various easily carried out tests and experiments, within the 
competence of most who have had any experience of elementary science, are 
suggested. The book is one that the elementary student and the grower will 
both be able to profit by. 
" Sweet Peas and Antirrhinums." By W. Cuthbertson. Ed. 2. 119 pp. 
8vo. (Clarke, London, 1920.) Paper boards, 2s. 3d. 
A past master in the art of growing and showing Sweet Peas and Antirrhinums, 
the raiser and introducer of many fine varieties of both, and an excellent judge 
of what is best in such popular flowers as these, we can have no better guide to 
their choice and cultivation. Both plants are plants for every garden ; both 
appeal in various ways to almost every gardener, both are useful for the decoration 
of the greenhouse, and both are good for cutting. Neither has yet reached the 
limit of its possibilities nor the maximum of its cultivation, and both the old 
gardener and the novice may turn to the pages of this little book with profit. 
" Dictionary of Botanical Equivalents — French-English, German-English." 
By E. Artschwager, Ph.D., and E. M. Smiley, M.A. 8vo. 137 pp. interleaved. 
(Williams & Wilkins,. Baltimore, 1921.) 
A useful, but unequally balanced book, whereof pages 1 to 15 comprise 
French botanical terms with their American equivalents, and the remainder 
German. Naturally, therefore, we find Mischling, but not Metis, and the like. 
We hope the next edition will give greater prominence to French terms, and that 
endeavours will be made to give the simplest exact equivalents. 
" Black's Gardening Dictionary." Edited by E. T. Ellis. 8vo. 1238 pp. 
(A. and C. Black, London, 1921.) 15s. net. 
We have examined this rather bulky work with a great deal of interest 
and much care, and arrived at the conclusion that it is a capital book for all 
gardeners, old or young, professional or amateurs, and likely to fill a long-felt 
want at a moderate price. The various writers are all well-known, able, and 
experienced, and it would be difficult to find a more capable body of men. 
Their knowledge has been admirably classified, and put together excellently, so 
that any subject can be easily found ; and so arranged that every subject is dealt 
with in a concise plain manner, so well put that even a novice can quickly 
grasp it. It would be exceedingly difficult to point out any features especially 
noticeable or worthy of special attention, as every section is most carefully 
dealt with. In most instances the common name is given, the botanical or other 
names, cultural details are admirably dealt with, the best proved varieties and 
most useful ones, manures, insect and fungus pests, and innumerable details 
of great importance, including the information of how to choose and make all 
kinds of gardens, such as market gardens, fruit gardens etc., which will prove 
of immense value to all concerned in such work. There is no index, but all 
is arranged in alphabetical order, rendering an index unnecessary. The whole 
is so good in every respect that we have no hesitation in saying all garden 
lovers should have this book. 
" The Garden of Earth." By Agnes Giberne. 8vo. xiv +178 pp. 
(S.P.C.K. London, 1921.) 65. 6d. net. 
This " little book on plant life, plant-growth, and the ways and uses of 
plants " is written in simple language, but gives an introduction to the ways in 
which plants live, so that the unlearned may get some idea of the miracles
