Plat 1 in the experiment was heavily fertilized during each of the years 1891 to 

 1904 with cattle manure. Plats 2 and 3 received during each year of the same period, 

 except in 1894, 1,200 kg. of Thomas slag and 900 kg. of kainit per hectare. In addi- 

 tion plat 2 received each year liquid manure and plat 3, 450 kg. of nitrate of soda per 

 hectare. Plat 4 received no Thomas slag or kainit, except in the year 1894. 



The average yield of fruit during the 13 years of the experiment on the different 

 plats was as follows: Plat 1, 5,547 kg.; plat 2, 5,485 kg.; plat 3, 5,430 kg.; and plat 

 4, 4,669 kg. The largest fruit on an average was secured on plat 3. The largest 

 amount of second-class fruit, 9.5 per cent, was found on plat 1, and the smallest 

 amount, 4.7 per cent, on plat 4. The wine produced was of practically like quality 

 on each of the different plats. 



Analyses of soils and the interpretation of the analytical results in the 

 manuring- of grapes, A. Hubert (Prog. Agr. et Yd. (Ed. V Est), 26 (1905), Xo. 50, 

 pp. 690-699, tig. 1) . — Chemical and physical analyses with descriptions of the methods 

 employed are given for a number of different soils, together with a table showing 

 the amounts of different kinds of nitrogenous, potassic, and phosphatic fertilizers to 

 use on different classes of calcareous and noncalcareous soils. 



Roses and how to grow them (New York: Doubledai/, Page & Co., 1905, pp. X-j- 

 189, ph. 32, Jigs. 4). — A popular manual containing directions for growing roses in the 

 garden and under glass, and designed more especially for the use of the amateur. 

 Much of the matter in the book has already appeared in magazine form. 



Carnation breeding, C. W. Ward (Gardening, H (1906), Xo. 321, pp. 129, 130, 

 figs. 3). — Brief historical notes on the carnation, with an account of the author's 

 methods of breeding carnations by hybridization and selection. 



It is stated that the annual value of the carnation product is between $5,000,000 

 and $6,000,000. A half interest in the variety Robert Craig, originated by the 

 author, is stated to have brought $10,000. The bulk of the profitable varieties origi- 

 nated by the author trace back to the variety General Maceo, which was a cross 

 between the English variety Winter Cheer and the American variety Meteor. 



The chrysanthemum, A. Herringtox (New York: Orange Judd Co., 1905, pp. 

 VIII-\-160, pi. 1, figs. 32). — Directions are given to professional growers and ama- 

 teurs for the culture of chrysanthemums. 



The main portion of the book is devoted to the production of large flowers such as 

 are seen at exhibitions and in flower stores. The work takes up in systematic detail 

 culture directions, beginning with the taking of the cuttings to the staging of the 

 blooms. Chapters are also given on raising chrysanthemums from seed, hybridizing 

 chrysanthemums, insect pests, and diseases. 



A chemical study on the culture of chrysanthemums, A. Hebert and G. 

 Truffaut (Bui. Soc. Chim. Paris, 3. ser., 33 (1905), Xo. 11, pp. 661-664).— The 

 authors cultivated the variety of chrysanthemums Madame Gustave-Henry out-of- 

 doors in a rich soil without the addition of fertilizers, and analyzed the plants at 2 

 different stages of growth. 



At the time of the first analysis, July 28, the plants had been growing 178 days and 

 the first buttons were appearing. Sixty-four days later, during the first days in 

 October, when the plants were in full bloom they were analyzed again. During the 

 last 64 days of growth the plants took daily 3 times as much nitrogen, 3 times as 

 much potash, 7 times as much phosphoric acid, 16 times as much lime, 20 times as 

 much magnesia, and 5 times as much sulphuric acid as during the preceding 178 days. 



It appears, therefore, that the most active growth of the chrysanthemum begins 

 during August and it is at that time that special attention to watering and the use of 

 soluble manures should begin. The analyses further show that for each part of 

 nitrogen taken from the soil during the first period of vegetation there was with- 

 drawn 1.42 parts of potash and 0.28 part of phosphoric acid, while during the second
