its appearance as yet in the vineyards of southern ITtali, but as a future protection 

 tlie use of resistant vines is urged. 



Experiments with commercial fertilizers for grapes, E. Zaciiakewicz {Prog. 

 A(jr. et 17/. {Kd. UEd), 25 {1904), Nos. 1, pp. 17-19; 2, pp. 37-40; 3, pp. 72-76).— 

 The varying results secured in cooperative fertilizer experiments with vineyardists in 

 a number of different localities are here reported in more or less detail. 



On the duration and variations in grafted vines, L. Deorully {Prog. Agr. et 

 Vit. {Ed. L'Ed), 25 {1904), ^o. 13, pp. 3S3, 3S4). — A controversial article in which 

 the author points out that the variations in characteristics of vines due to grafting 

 are not sufficient on the whole to cause vineyardists any apprehension. The thou- 

 sands of acres of French vineyards which have been reconstructed on American 

 stocks still continue in a thriving condition and produce an abundance of wine 20, 

 25, and 30 years after grafting. The subject of variations brought about as a result 

 of grafting is wholly in an experimental stage, and as yet is of scientific interest only. 



Notes on the reconstruction of French vineyards by grafting, L. Daniel 

 {Rec. Vit., 21 {1904), Nos. 532, pp. 210-215; 534, pp. 269-275; 535, PP- 301-305).— 

 Contrary to the general belief, grafting has been found to change the character of 

 the scion graft as well as of the wine produced from the fruit grown on it. The 

 variation in vine and product is due in a large measure to change in nutrition which 

 takes place as a result of the callusing of the grafted parts, and the consequent 

 greater difficulty of sap circulation. By taking advantage of the changes thus 

 brought about it is believed that it will be possible to produce by grafting new varie- 

 ties which shall combine the good qualities of the French grapes with the phylloxera 

 resistance of the American sorts. Grape growing by the use of direct producers is 

 considered highly desiraljle, and scientists are urged to experimenf^along the line of 

 the production of new varieties, by means of grafting, which shall be direct pro- 

 dut-ers. 



Report of the viticulturist, R. Bragato {New Zealand Dept. Agr. Rpt. 1903, pp. 

 451-461). — This deals largely with the results secured in tests of varieties and in the 

 analyses of must and wine obtained from Euroj^ean varieties of grapes. A paper 

 read by the author at the recent meeting of the Auckland Fruit Growers' Union on 

 phylloxera pest in vines is included in the article. 



Experiments on the coloration of lilac flowers due to forced culture, E. 

 Laurent {Bui. Agr. [Brussels], 19 {1903), No. 5, pp. 659-669). — It is stated that in 

 the winter forcing of lilacs the flowers obtained are usually white; and this is true 

 even when varieties normally producing violet-colored flowers are forced. The 

 author made a series of experiments to determine the cause of the production of 

 white flowers. The results obtained are recorded in detail, but they are conflicting 

 and no general conclusions are drawn. 



Pictorial practical chrysanthemum culture, W. P. Wright {London and New 

 York: Cassell A Co., Ltd., 1904, pp. I'S, figs. 63). — This is a practical treatise on the 

 culture of home and show chrysanthemums, dealing with all the different phases of 

 the plant from propagation to final exhibition. It is the sixth of this series, and as 

 in the earlier numbers, pictures form a prominent and valuable feature of the book. 



Alabama-grown bulbs for forcing, W. J. Stewart {Amer. Gard., 25 {1904), 

 No. 478, p. 223). — This is a report on the blooming of the Paper White Narcissus 

 grandriflorum and N. princeps from bulbs grown in Alabama. It is reported that the 

 Paper Whites Which flowered were very fine and fully equal to imported stock. 

 "There were, however, a good many 'sets' in the collection, the bulbs evidently 

 having been grown in a clump and taken up as such and separated." It is believed 

 that had the sets been i)lanted out as is done in general bulb culture and grown for 

 one season they would have made a much better showing. The results with N. 

 princejjs were not so satisfactory, and in the opinion of the experimenter the climate 

 of Montgomery is too warm for the growing of bulbs of this class.
