740 EXPERIMENT STATION EECOED. 



The data gathered with regard to the effect of grafting include its influence 

 on the graft, on the form of leaves, the resistance to cryptogamic maladies, and 

 the period of maturing, as well as its effect on the content of alcohol and sugar 

 in the wine. The author concludes that the variations in sugar and acid con- 

 tent of the wine are of the same order and of the same amplitude as variations 

 which have been noticed in the French vines themselves. With all other in- 

 fluences identical, such as climate, soil, culture, season, etc., a definite stock 

 does not exert the same influence on scions of different varieties, and opposite 

 variations may be noted from year to year where scions of the same variety 

 are grafted on similar stocks. When the scions from native vines are grafted 

 on various American stocks the results are equally confusing when compared 

 with the behavior of similar scions growing on their own i-oots. No unusual 

 A-ariation was noted with regard to the form of the leaves and grapes, the 

 period of maturity, etc. In short, in spite of the numerous grafted stocks 

 studied during a period of 5 years, grafting does not appear to have produced 

 anything new. 



Rotundifolia grapes, C. C. Newman (South Carolina Sta. Bui. 132, pp. 18, 

 figs. 8). — Popular directions are given for the propagation, planting, pruning, 

 training, fertilizing, and cultivation of the Rotundifolia type of grapes, to- 

 gether with descriptive notes of the more important varieties and data on 

 some pruning experiments conducted to dem-onstrate the evil effect of late 

 pruning. 



AVith vines cut in October and November no bleeding took place, even when 

 gi-owth started in the spring. Where pruning is delayed until after December 

 there is considerable loss of sap in the spring, and growth commences from 

 a week to 10 days later than with vines pruned in the early fall. From one 

 vine that was cut March 20, 23 lbs. of sap were collected in 4 weeks' time. The 

 entire vine appeared to be affected and its growth considerably checked. 



As a result of this work it appears advisable to prune during the months of 

 October and November. 



Notes on the operations of the royal American grape nurseries in Asti 

 L Italy] from 1901 to 1906, G. PERsf (Bol. Ufflc. Min. Agr., Indus, e Com. 

 [Rome], (1007), III, Xo. 8, pp. 919-929).— This is a report on the operations 

 conducted at the govei*nment grape nurseries at Asti in the production and dis- 

 tribution of grafts and cuttings of American vines. 



Tables are given showing the species and varieties grown, and the number of 

 vines distributed from 1001 to 1900, inclusive, together with data on grafting 

 experiments and an outline of the course of instruction given at the grafting 

 school. In all a total of 1,365,628 grafts and cuttings of American vines and 

 hybrids were distributed from 1901 to 1906. inclusive. 



The hybrid direct bearers at the Philippeville agricultural school in 1906, 

 F. GoDARD {Bid. Off. Gouvt. Gen. Algerie, 1907, Xo. 17, Sup., pp. 287-315)'.— 

 This is a report on investigations made with all the well-known hybrid direct- 

 bearing grapes in order to determine those most suitable for cultural purposes 

 in Algeria. Notes are given on all the varieties tested, together with lists of 

 those varieties resistant to cryptogamic maladies and drought, as well as the 

 most productive kinds. 



The spindel tree. A suitable dwarf tree form for coiTiniercial fruit grow- 

 ing (Ber. K. Lehranst. Wein, Olist u. Gartenhau Gciscnheim, 1906, pp. Ji9-53, 

 figs. 2; ahs. in Deut. Lancliv. Pressc, 3J, (1907), No. 75, i)p. 598, 599, figs. 2).— 

 Comparative data are given with regard to the training of dwarf fruit trees at 

 the horticultural school at Geisenheim on the Rhine. 



The three forms used were the bush, pyi-amid, and spindel shape trees, of 

 which the last-named is said to have given highly satisfactory results. This
