The plums of New York, U. P. Hedrick et al, {^Jew York State Sta. Bpt. 

 1910, pt. 2, pp. XII-\-616, pJs. 100). — This is the third ot a series of monographs 

 on the fruits of New York (E. S. R., 20, p. 940). Although the work has a 

 special significance for New York State, its contents are considered sufficiently 

 general to be offered as a record of the present knowledge of cultivated plums 

 and to be applicable to the whole country and more or less to the world. 



In the first chapter the history and general characters of plums are dis- 

 cussed; a conspectus showing the relations of the species to each other is given; 

 and each species is described and discussed in detail relative to its literature, 

 botanical characteristics, and varietal groups. Chapter 2 discusses the present 

 status of plum culture in America under the following headings: Climate, the 

 pollination of plums, locations and soils, stocks and propagation, plum orchards 

 and their care, harvesting and marketing, diseases, and insects. A table is 

 given showing the averages of the blooming dates at the New York State Station 

 of varieties of plums for the 8 years 1902 to 1909. Chapter 3 describes the lead- 

 ing varieties of plums. The technical descriptions are for the most part 

 original and the aim has been to give a concise idea of all of the characters of 

 each variety. Synonyms and important references ai'e also given. Chapter 4 

 contains briefer descriptions of the minor varieties of plums. 



The color plates of species and leading varieties are a valuable adjunct to the 

 text. A bibliography is given containing all horticultural books in America 

 dealing with the plum, together with the European books and all periodicals 

 referred to in the volume.

 [English Ed.], 5 (1912), No, 3, pp. 123-132, pis. 2, fig. ]).—An account of the 

 roselle (Hibiscus sahdariffa) relative to its history, botany, and geographical 

 distribution; varieties; soil, planting, and cultivation: harvesting and yield; 

 composition and uses; diseases; and insect pests. 



The only disease that has been thus far noted on the roselle is the mildew 

 (O'idimn sp.), which was found in Florida to attack the plant in the cool, damp 

 fall nights. This is easily controlled by dusting with dry sulphur when the 

 plants are wet with dew.
