of various types. Chapters are also included on exliibiting roses and llae ene- 

 mies of the rose. A list of jrood roses for garden cultivation is appended. 



Injuries to the rose by animals, M. Schwartz (In Rosenkrankheiten und 

 Rosenfeinde. Jena, 1910, pp. 35-50). — Some 50 species of animals are briefly 

 described and tabulated according to the parts of the plant that they injure. 

 Remedial measures are briefly noted. 



Cut-flower industry in southern France, F. M. Mansfield {Daily Cons, 

 ami Trade Rpts. [U. S.], U, (1911), No. 87, pp. 193-200, fig. i).— An account of 

 the cut-flower industry of southern France, with special reference to methods 

 of preparing the flowers for market and facilities for expeditious and econom- 

 ical distribution of the product. 



FORESTRY. 



Familiar trees and their leaves, F. S. Mathews (Xew York and London, 

 1911, 3. ed., pp. XVII +33^, pin. 15, figs. 221).— This is the second revised edi- 

 tion of this work (E. S. R., 8, p. 135). The revision largely relates to the sci- 

 entiflc nomenclature, which follows the initiative of the seventh edition of 

 Gray's Manual, revised by B. L. Robinson and M. L. Fernald (E. S. R., 20, p. 

 326). 



The supplement contains an addition of some 20 species new to the book, 

 together with a systematic index of the names of trees of the eastei'u Ignited 

 States, including the botanical names according to A. Gray and C. S. Sargent. 



The hardy catalpa in Iowa, C. A. Scott (loiva Sta. Bui. 120, pp. 309-325, 

 figs. 5). — This bulletin contains directions for establishing and caring for plan- 

 tations of hardy catalpa (Catalpa speciosa), discussing the range of successful 

 growth, form and size, selection of species, propagation from seeds, planting 

 stock, soil requirements, preparation of planting site, time of planting, spacing, 

 cultivation and care of plantation, protection against rabbits, cutting back, 

 fungus diseases, length of rotation, second crop, time of cutting, seasoning, and 

 durability of catalpa wpod. 



Nearly all the hardy catalpa plantations in the State have been studied by 

 the forestry section of the station. A large majority of these plantations have 

 proved successful, and the results obtained on some of them are given. The 

 gross annual return per acre on the plantations studied varied from $10.77 to 

 $20.34. Eighteen-year-old trees that have been properly cared for will yield 

 from 2.000 to 2,500 posts to the acre. 



The hardy catalpa is of special importance in Iowa for the production of 

 fence posts. The annual destruction of the late growing terminal shoots at the 

 approach of winter, coupled with the liability of older trees to fungus attacks, 

 results in very crooked and, generally, diseased poles. Hardy catalpa posts 

 which have not become infected by fungi before cutting and which are properly 

 seasoned rank next to Osage orange and red cedar in durability. They season 

 best if cut in November or December, but if a second crop is desired from sprout 

 reproduction, the flrst cutting should be made in February or March. The most 

 common cause of failure with catalpas is attributed to the substitution of the 

 common catalpa (Catalpa catalpa), which is not hardy enough for Iowa. It 

 can be distinguished from the hardy species by diflierences in the bark and 

 seeds. 



The oak: Its natural history, antiquity, and folklore, C. Moseley (io»- 

 don, 1910, pp. IX + 126, /j/.s\ .'^). — This popular work deals largely with the his- 

 tory of the oak in the British Isles. 



Some notes on jack pine (Pinus divaricata) in western Ontario, L. M. Ellis 

 (Forestry Quart., 9 (1911), Ao. 1. pp. 1-14, P^- !)■ — These notes, which are
