A complete work on the pruning of fruit trees, J. F. Moody (Perth, Western 

 Australia: Govt., 1912, pp. 135, figs. 175). — A treatise on the pruning of all kinds 

 of fruits and nuts grown in Western Australia. 



ITew dosage tables, C. W. Woodwoeth (California Sta. Bui. 257 (1915), pp. 

 3-16, figs. S). — A new principle applicable to the construction of dosage tables 

 was discovered while making a careful comparison of the rate of charge in 

 the dose necessary to compensate for the differences in leakage. The prin- 

 ciple is that an arithmetical series of leakages is related to a geometrical 

 series of dosages and both correspond to the same complex series of sizes of 

 tents. 



This bulletin discusses the application of the above principle to the construc- 

 tion of dosage tables and points out the errors in the tables commonly used. 

 A set of tables based on the new principle is given and discussed.

 tion of serial accounts of German fruits started in 1905 and consisting of sets 

 of three parts with descriptions of four varieties of fruit in each part (E. S. R., 

 24, p. 641). The annual sets of the years noted continue descriptions of pear 

 and apple varieties and also describe a number of currants, gooseberries, and 

 cherries. The descriptions and illustrations follow the arrangement in the 

 sets previously noted. 



Recent progress in fruit production in Hungary, D. Angyal and J. Gyoky 

 (Internat. Inst. Agr. [Rome], Mo. Bui. Agr. Intel, and Plant Diseases, 6 (1915), 

 No. 5, pp. 652-657). — A short account of the fruit industry in Hungary with 

 reference to climatic conditions, distribution of the chief species of fruit trees, 

 native and foreign varieties, area of orchard lands and estimated yields, re- 

 search work and education, state encouragement of the fruit industry, and 

 associations. 



Fruit packing and the marketing and exporting of fruit, J. F. Moody and 

 J. Ramage (West. Aust. Dept. Agr. Bui. 46 (1915), pp. 77, figs. 108). — A treatise 

 on the packing and marketing of citrus and deciduous fruits with special refer- 

 ence to the preparation of fruit for the export trade. 



The pollination of the pomaceous fruits. — II, Fruit bud development of 

 the apple, F. C. Bradford (Oregon Sta. Bui. 129 (1915), pp. 10, pis. 6).— This 

 is the second of a series of studies of the pollination of pomaceous fruit 

 (E. S. R, 29, p. 541). 



In the present bulletin the author describes and illustrates with a series of 

 plates the development of fruit buds of the Yellow Newtown apple. Buds were 

 gathered throughout the v/ork in six separate classes as follows : Axillary buds 

 on the newest wood ; terminal buds on the newest wood ; buds from young 

 spurs on second-year wood which had not borne fruit but seemed likely to bear 

 in the following year; buds from spurs which were bearing in the current 

 year; buds from spurs which had borne previously but had not blossomed in 

 the current season, in other words, were " resting a year ; " and buds from spurs 

 which had blossomed but which had not set fruit, or having set fruit, had lost 

 it early through dropping or thinning. Consideration is given to fruit bud 

 differentiation in these various classes. A bibliography of literature cited is 

 appended. 



The earliest differentiation in fruit buds was visible during the first ten 

 days of July, there being possibly a slight variation from year to year. Samples
