1755. BuNYARD, E. A. A handbook of hardy fruits. Apples and pears. 205 p. John 

 Murray: London, 1920. — '*This volume is designed to fill the place formerly occupied by 

 Dr. Hogg's Fruit Manual, which has now been out of print for some time. In preparing the 

 present handbook, the author has endeavored to provide information in a popular form with- 

 out any loss of accuracy." A classification and Key is given for both apples and pears, 356 

 varieties of the former being described and 157 of the latter. — /. H. Gourley.

Informe An. Estac. Exp. Agron. [Cuba] 1918-1920: 1-786. 329 fig. 1920.— During the 2 years 

 under review experimental work has been carried on with a wide range of economic plants, 

 including both indigenous and exogenous ones. The work has included varietal and cultural 

 tests with the following plants: Sweet potatoes, cassava, malanga {Xanthosoma sp.), Dio- 

 scorea spp., Maranta arundinacea, Calathea allouya, Cacara erosa, many types of Cucurbits 

 (including Sicania odorifera, Trichosanthes anguira, Benincasa spp., Cucurbita moschata, 

 Lagenaria leucantha), tomatoes, peppers, cabbage, brussels sprouts, Solanum muricatum, 

 Jatropha urens var. inermis, strawberries, pineapple, banana, plantain, citrus, mango, coffee, 

 cacao, grape, and Clitoria ternatea. — John A. Stevenson. 



lib". Chasset, L. Quelques traces de ftxite chez certaines varietes fruitieres. [Some 

 traces of fixity of certain varieties of fruits.] Rev. Hort. 93: 298-299. 1921. — The seedlings 

 of a number of varieties of apples and of pears often closely resemble the parents in various 

 characters. Many examples are listed. It is possible that through long cultivation and 

 vegetative multiplication of a variety greater fixity of its characters may be brought about. —

1762. Georgeson, C. C, and C. H. Benson. Report of work at Sitka station. Rept. 

 Alaska Agric. Exp. Sta. 1918: 22-33. 1920.— In the strawberry breeding work about 3000 

 seedlings fruited for the 1st time, and 1800 new seedlings were growTi. One salmonberry- 

 raspberry hybrid of 1916 bore promising fruit. Growing potatoes from seed balls is being 

 continued with good results. Some crossing has been done with flowering plants. Vege- 

 tables which are favorably reported upon are: Cabbage, cauliflower, brussels sprouts, kale, 

 kohl rabi, turnips, rutabagas, carrots, parsnips, parsley, chard, lettuce, radishes, peas, celery, 

 and rhubarb. Chinese cabbage, beets, onions, leek, and spinach are not so satisfactory. 

 Orchard fruits were reported upon unfavorably. Red raspberries, especially the Cuthbert, 

 gooseberries, and currants produced well. Hybrids of Ribes bracteosum and R. nigrum pro- 

 duced fruit for the 1st time. Blueberries, dewberries, and blackberries are being tested. 

 The eastern cranberry is a failure. Comparatively few ornamental trees and shrubs seem 

 adapted to the climate. Rosa rugosa grows especially well, and 20 other roses survived the 

 winter though 9 did not; 43 hardy perennials and 32 annuals are reported as satisfactory, 

 while 2 perennials and 8 annuals were not successful. — /. P. Anderson.
