the dormant season, and In the second of the leaf and flower buds of some 

 peaches and apricots. 



Summer pruning the peach, C. A. Keffer (Tennessee Sta. Bui. 108 (1914), 

 pp. 205-S12, figs. 9). — This comprises a discussion of summer pruning the peach 

 as a means of developing fruiting wood on the lower part of the main or skeleton 

 branches which are usually bare. The subject matter is based upon the results 

 of pruning tests conducted at the station and herein noted. 



Some fertilizer tests In vineyards, F. H. Hall {New York State Sta. Bui. 

 381 (1914), popular ed., pp. 3-8). — A popular edition of the bulletin previously 

 noted (E. S. R., 31, p. 339).

 {Rev. Vit., 42 {1914), No. 1074, pp. 57-60, figs. S).— The author reports the 

 successful renovation of old grapevines by means of layering. 



Strawberry culture, A. K. Gardner and H. P. Sweetser {Bui. [Maine] Dept. 

 Agr., 13 {1914), No. 3, pp. 28, pi. 1, figs. 13).— A popular treatise. 



Summary of preliminary Feijoa pollinating experiments, K. A. Ryerson 

 {Univ. Cal. Jour. Agr., 2 {1914), No. 2, pp. 51-53). — Preliminary experiments 

 conducted by the author in 1913 and 1914 relative to the nonsetting of fruit with 

 the feijoas {Feijoa sclloiviana) indicate that the blossoms are largely sterile to 

 their own pollen and that the trouble may be overcome by mixed plantings of 

 different varieties. 



The Siamese pomelo^ H. H. Boyle {Jour. Heredity, 5 {1914), No. 10, pp. 

 Jf40-444< fig- !)• — The author describes four types of seedless pomelos obtained 

 from Siam for the Philippine Bureau of Agriculture. Two of these types are 

 considered to be both excellent in quality and desirable for market purposes. 



Tea: Green manuring at the experiment station, Peradeniya, ]\I. K. Bamber 

 {Dept. Agr. Ceylon Bui. 9 {1914), PP- 119-134, pls. 3). — A progress report on the 

 pruning, cultivation, and manuring experiments with tea at the Peradeniya 

 station (E. S. R., 25, p. 139). Summarized data are given showing the yields 

 of tea on the various plats for 1906 to 1913, inclusive.

Classification of daffodils for use at all exhibitions of The Boyal Horti- 

 cultural Society {London: Roy. Hort. Soc., 1914, PP- 73). — In the present 

 classification, which is designed for exhibition purposes, the daffodils are 

 divided into eleven divisions. A general list is then given of all known vari- 

 eties, and each variety is referred to its proper class or division in so far as 

 the varieties are sufBcently well-known to be clasified. 



Preserving cut flowers, L. Knudson (Amer. Florist, 43 {1914), ^o. 1376, 

 pp. 649, 650). — Some experiments were conducted by B. M. Dnggar and the 

 author in 1908 and by the author and Lua A. Minns in 1913 to determine 

 whether or not the keeping quality of flowers can be prolonged by special meth- 

 ods of treatment. In the experiments here described a large number of chemical 

 solutions of different concentrations were tested with reference to their value 

 for prolonging the life of flowers of relatively short duration of life. 



Over 10,000 cut flowers were used in the experiments, including the following 

 kinds : Cosmos, petunia, aster, verbena, violet, coreopsis, dahlias, Tagetes erecta 

 (African marigold), T. patula, geranium, zinnias, sweet peas, and pansles. The 

 results did not at all substantiate the favorable work secured by Fourton and 

 Ducomet (E. S. R., 18, p. 44) and in no case were any striking results secured. 

 An increase of a day or so in the keeping qualities was frequently obtained but 

 it is believed that this might have been due to other causes. With certain
