Japanese, and Philippine teaching have not been altogether lost. A 

 forest school was established at Mukden in 1907, and a foreign adviser 

 to the Bureau of Forestry was appointed in 1913 ; so that it may 

 not be altogether too late to remedy past waste. 



In Part II. a few little slips, such as Holoxylon amnodendron for 

 Haloxylon ammodendron, the styling Biota orientalis and Cupressus 

 thyoides " varieties," and the statement that Ginkgo " represents the 

 sole link between trees and ferns now surviving," show that the author 

 is not a botanist ; but he has made most intelligent use of the work 

 of those who have preceded him, of which he gives a useful 

 bibliography ; and the net result is an interesting and useful book. 



" Bulbs and their Cultivation." By T. W. Sanders. Ed. 2. 8vo. 

 198 pp. (Collingridge, London, 1915.) 25. 6d. net. 



A very practical treatise on the cultivation of bulbs both under 

 glass and outside ; tuberous-rooted plants are also included. The 

 best varieties, storage, propagation, pests, and diseases are all ably 

 treated of, and manures have not been forgotten. Printing and 

 illustrations are good, and a capital index completes the book. 



" Rock Gardens and Alpine Plants, including Water, Bog, and 

 Moraine Gardens." By T. W. Sanders. 8vo. ,206 pp. (Collingridge, 

 London, 1915.) 3s. 6d. net.

 is well worth the study of all readers and contains much sound advice ; 

 in fact, sound practical information is a great feature of the whole 

 book, and we hope all lovers of this class of plants will read it. There 

 is a very good index.

This addition to the ' Rural Science Series ' treats of the cultivation 

 and marketing of oranges and lemons and kindred fruits of the Citrus 

 family, with special reference to practices and climatic conditions 

 obtaining in California and Florida. In both these States the Citrus 

 industry has attained an important position and is progressing 

 rapidly, and the methods of cultivation adopted and the business- 

 like organization of the industry are characteristically American. 



Hitherto the literature relating to the industry has been scattered 

 through a large number of periodicals and reports, as is indicated by 

 the extensive bibliography appended to this volume, and the aim 

 of the author has been to select and bring together the more valu- 

 able parts of this information and to describe the industry as it
