author follows Schimper and borrows some of his pictures of scenery. 

 Vol. TV. continues botany, and deals with various forms of temperate 

 and polar zones ; aquatic vegetation ; general and applied ecology. 



This will be sufiicient to guide the reader to the extent and char- 

 acter of the work, so far as horticulture is concerned. 



Two sectional models of the rose and the frog are issued with the 

 work. The rose consists of five plates so constructed that they over- 

 lap one another. The first is the complete flowering branch, the second 

 has the epidermis removed. The third shows assimilation, the fourth, 

 by means of coloured lines down the stem, the movements of water 

 and food-stuffs, and the fifth a large number of details, the interior 

 dissections shown by lifting up little flaps over the parts. It is very 

 well executed, but the truest pupils will not " cram " up their know- 

 ledge of the- rose without dissecting it for themselves. 



" The Study of Com." By Vernon M. Shoesmith. 8vo., 96 pp., 

 including many illustrations and figures. (Orange Judd Company, 

 New York, 1910.) 2s. 6^^. 



This httle handbook is intended as a practical guide for the study 

 of Zea Mais as a corn-producing plant. There are many excellent 

 illustrations, and the whole work is admirably got up. As maize is not 

 grown as a corn crop in England it is not likely this little work will be 

 extensively read here; it, however, shows how thoroughly our American 

 friends study matters of great economic importance to them. 



" The Standard Cyclopedia of Modem Agriculture and Eural 

 Economy." By various authors; edited by Professor E. Patrick 

 Wright. 8vo., vol. 9. 256 pages and many plates. (The Gresham 

 PubHshing Company, London, 1910.) 8s. net. 



This volume is on the lines of the preceding eight. To be of much 

 Qse the set of twelve will be necessary. The utility of the whole will 

 depend largely on the index, and doubtless the work will be then more 

 fully appreciated. 



The present volume deals among other subjects with milk, oats, and 

 pastures. There are many short articles in this volume, as in the 

 others, on gardening subjects by Mr. W. Watson, of Kew, and these 

 alone make the work of considerable interest to gardeners. We advise 

 Fellows of the Society who have not other easy access to this work to 

 examine it in the Lindley Library, more especially when looking up an 

 agricultural or horticultural subject for the first time.
