642 EXPERIMENT STATION RECORD. 



Some experiences with seedling canes in British Guiana, F. J. Scard ( West 

 Indian Bid., 1 {1900), No. 4, PP- 380-386). — A number of promising seedling canes 

 have been grown in comparison with the Bourbon variety. The results obtained 

 have been contradictory. 



Tobacco culture, J. C. Espin {Bui. But. Dept. Trinidad, 1900, Oct., j)p. 291-304). — 

 This bulletin deals popularly with the culture of tobacco, including harvesting, cur- 

 ing, packing, and baling in Cuba and neighboring islands. 



Experiments with grain and the necessity of regularly conducted field- 

 fertilizer experiments, M. Fischer {Fii]dAii(/i< Landw. Ztg., 49 {1900), Xos. 6, pp. 

 220-229; 7, pp. 248-256). — Fertilizer experiments with wheat after potatoes and with 

 oats are reported, the purpose of which is to show that because of the wide variation 

 in soils and conditions of different localities, each farmer must carry out his own 

 experiments on his farm. Before beginning such an experiment, a definite plan 

 should be outlined. A general scheme is submitted covering fertilizer trials on light 

 and heavy soils. The 3 jwints covered are (1) determining the fertilizing elements 

 needed; (2) the most profitable amomit of fertilizer; and (3) the most suitable form 

 of the fertilizer. 



Experiments on wheat at Ghizeh, G. P. Foaden {Jour. Khedir. Agr. Soc. and 

 School Agr., 2 {1900), No. 4, pp- 160-169). — In variety tests at the station Indian 

 wheats have been found much superior to the ordinary wheat of Egypt. JNIuch bet- 

 ter crops have been secured by watering twice, i. e., when the crop is about 14 in. 

 high and just when the flowering stage is reached, than when only 1 watering is 

 given. When the crop is not watered at about the time it is coming into ear, the 

 grain is often small and shriveled in appearance. In the fertilizer experiments the 

 most beneficial results were obtained by the use of nitrate of soda. 



Analyses of varieties of wheats {Ann. Agr. Sui-^s^e, 1 {1900), No. 2, pp. 74, 75). — 

 Analyses, with reference to protein, of 30 varieties of wheat. 



Weak straw, J. A. Murray {Ann. Rpt. Field Expts., Univ. Col. Wales, 1899, pp. 

 79, 80; abs. in Jour. Chern. Soc. [London'], 78 {1900), No. 453, IT, p. 498). — Analyses 

 are reported of two lots of rye straw (1) manured with phosphates, nitrogen, and 

 potash, and (2) with phosphates and nitrogen only. The straw in the latter case 

 was too weak to stand, and when dried was so brittle that it could almost be reduced 

 to powder by crushing in the hand. Results indicate that the weakness of the straw 

 was probably due to a deficiency of oil. 



HORTICULTURE. 



On the limits of the possibility of grafting plants, L. Daniel 



{Compt. Rend. Acad. !Scl. Far is., 131 {1900), Xo. o, pp. 192^ 193; Jar- 

 din, 11^ {1900), No. 325, pp. 271, 272).— Kn account is given of 12 

 unusuftl unions between plants belonging to different families, obtained 

 by grafting b}' approach. Successful grafts were made between seed- 

 lings of the following plants: Kidney bean and cocklebur, kidney 

 bean and castor-oil bean, sunflower and melon, cabbage and tomato, 

 chrysanthenumi and tomato, Jerusalem artichoke and black night- 

 shade, coleus and acaranthus, cineraria and tomato, aster and phlox, 

 coleus and tt)mato, maple and lilac, zinnia and tomato. 



The most perfect grafts in these experiments were made between 

 plants nearest alike in vigor and vegetation. The nature of the tissue 

 of the diflerent plants also played an important role. The tomato and
