 ])jt. 112, }>h. 9, Ji(jx- 8). — This is the sixth volume of the series of Handbooks of Prac- 

 tical (iardening, edited by II. Roberts. It deals primarily with apple culture in 

 England, including descriptions of de.ssert and cooking varieties of apples most prom- 

 inent there, and includes chapters by the editor on the history and cookery of apples 

 and on the preparation of cider. English methods of apple culture are so different 

 from those observed in this country that the book will l)e found of but little practical 

 use to American orchardists.

 32, figs. 9). — The general characteristics, history, and classification of the Chinese 

 cling grou{) of })eaches are given, together with historical and descriptive notes of 

 65 varieties. Synonyms of these varieties are also given. In this work the author 

 has endeavored to revise the nomenclature of the group and simplify the names. 

 The name "Chinese cling group" is believed to be more exa»'t than "Northern 

 Chinese race," by which the group is (piite generally known, and is therefore pro- 

 posed for it. The varieties of this group most largely grown are stated to be (Jreens- 

 boro, Carman, Thurl)er, Georgia, and Elberta. 



Variations in olives during ripening, C. E. Zav {Staz. Spn-. Acp-. Jlal., 34

 re])orte<l. 



The fig, R. II. PKitE and E. A. White {Texas Sta. Bui. 62, pp. 17-29, ph. 12).— 

 A brief discussion is given of fig culture in Texas, including details for propagation, 

 fertilizing, planting, and pruning. Various kinds of figs are classified and descriptive 

 notes given of 20 varieties. The correct nomenclature of the different varieties has 

 been made a special feature of the bulletin. The variety (juite generally known as 

 the ^Magnolia fig has been foimd to be identical with Brunswick, Clare, and P>arni- 

 sotte. Eigs are not extensively grown in Texas, and their more general u.se is advo- 

 cated. The folloVing varieties, mentioned in the order of their productiveness, have 

 been successful on the station ground: Brown Turkey, Black Marseilles, White Mar- 

 seilles, Brunswick, Violet de Bordeaux, Early Violet, Pitaieuse, Brown Marseilles, 

 Negro I^argo, Grosse \'erte, antl Angelique.
