Value of hybrids for wine, J. R. Ciievrier ( Troisihne Congres Internntional de 

 Defense contre la Grele et de V Hybridation de la Vigne. Lyons: Sor. Reg. Vit., 1902, II, 

 pp. 142-203). — The value of a large number of hybrids for wine making is discussed 

 and sliown in tables of analyses. 



The affinity of Vitis vinifera with V. berlandieri, T. V. Mrxsox {Troisieme 

 Congii's International de Defense contre la Grele et de V Hybridation de la Vigne. Lyons: 

 Soc. Reg. Vit., 1902, II, pp. 139-142). — T'. berlandieri, in the author's experience, has 

 jjroved one of the most satisfactory stocks for various varieties of T'. vinifera. It is 

 one of the most resistant species to fungus diseases and jihylloxera. It is very 

 resistant to drought. 



The eflfect of phosphoric acid on the quality of w^ines and on the gray 

 rot, E. Makke {Prug. Agr. et Vit. {Ed. L'EM), 23 {1902), Xu. 2, pp. 39, 40).— In 

 tliese experiments tlie vineyard was manured the first year with barnyard niaimre 

 at the rate of 35,000 kg. per hectare; the second year with superphosphate, 500 kg. 

 per hectare; the third year no manure was given. Since the employment of tne 

 superphosphate regularly the vines have been more vigorous and less subject to the 

 "coulure," and there has been an increase in the production of about one-third. 

 The maturity of the grapes on the plats manured with superphosphates has been 

 hastened about 8 daj^s, and the body of the wine increased from 1 to IJ degrees. 

 The leaves, shoots, and fruits seemed more resistant to fungus diseases. Thus in 

 1900-1901 it is estimated that 1 10 of the grapes was destroyed by the gray rot on 

 the plats fertilized with barnyard manure, while on the superphosphated plats only 

 about 1 200 was destroyed. 



Contribution to the preparation of orchard fruit wines, E. Hotter {Separate 

 from Ztschr. Landv:. ]'erK)i_cJiKii\ Oesterr., -5 {1902), pp. 63). — This consists of a discus- 

 sion of the cider and berry industries in the more important fruit-producing districts 

 of Europe, the characteristics of certain varieties of fruits best suited for cider pro- 

 duction, and the results of a number of experiments with different machines for 

 pressing out cider. Both apples and pears are considered; and these are classified 

 and their comi")Ositlon as regards sugar, acid, total extract, etc., is given in a series of 

 tal)les. The analyses of the wines produced are also tabulated. 



Pecans, F. H. Burxette, W. C. Stubbs, and H. A. Morgan {Louisiana Stns. Bui. 

 69, 2.ser.,pp. 850-884, figs. 19). — This is a popular discussion of pecan culture in 

 Louisiana, giving methods of propagation, including budding and grafting, and the 

 subsequent treatment to be observed in the nursery and orchard. A number of the 

 better varieties are illustrated and briefly described. The States in which a number 

 of the different varieties originated are also given. Seedling trees planted at the 

 station in 1895 had reached a diameter of 11 J in. and a height of 34 ft. by 1902. The 

 final chapter gives a brief discussion of pecan insects, with suggestions as to the best 

 methods for their control. 



The shrubs of Wyoming, E. E. Nelson ( Wyoming Sta. Bui. 54, PP- 47, ph. 5, 

 figs. 16). — This bulletin has l;)een prepared as an aid in the identification of native 

 shrubs, with the hope that it may be instrumental in interesting the people of the 

 State in the more general planting of shrubs for home decoration. It is stated that 

 most of the cultivated shrubs of the Eastern States will not thrive in Wyoming, 

 especially in the higher altitudes. Brief popular descriptions are given of a large 

 number of different shrubs belonging to 23 different families of plants. The bulletin 

 is indexed with both the Latin and common names of the different shrubs described. 



Bulb culture in North Carolina, W. F. Massey {Amer. Florist, 19 {1902), No. 

 742, pp. 146-148) . — The author has been growing bulbs experimentally for a number 

 of years in North Carolina, and here summarizes the results of his work. It has 

 been definitely determined that sections about Raleigh, and all that portion of the 

 State known as the lower Piedmont countrv, east of the Occoneechee, are unsuited
