HORTICULTURE. 945 



About 6 weeks after planting, the Maine cuttings bad made an average 

 growth of 2.06 in., the New York cuttings 1.6 in., and the Louisiana 

 cuttings 1.3 in. The difference in the growth of the grape and poplar 

 cuttings from different States is shown in plates. 



Potatoes from Maine and New York were grown under like conditions 

 in a greenhouse. Crane June Eating potatoes of New York stock and 

 grown for a single season in Maine were compared with others of the 

 same stock grown continuously in New York. Similarly, Early Eose 

 potatoes of Maine stock and grown in New York but a single season 

 previous to the experiment were compared with others of the same stock 

 grown continuously in Maine. little difference was observed in the 

 rapidity of germination in either case between the Maine and the New- 

 York potatoes. In both cases the plants from tubers grown in Maine 

 had much darker green foliage, grew larger, and yielded a larger crop 

 than plants from tubers grown in New York. The increased yield was 

 shown in the greater size rather than in the greater number of tubers 

 produced. 



A number of experiments on the germination of seeds of various 

 varieties of corn, beans, and watermelons grown in the North and the 

 South are quoted from a thesis presented to Cornell University by 

 Messrs. 1 Joyce and Atwood. The results indicated that northern-grown 

 seeds germinate somewhat more rapidly than southern-grown ones. 



The author believes that these experiments are sufficient to establish 

 the superiority of northern-grown seeds, potato tubers, and hard-wood 

 cuttings, a northern climate having a tendency to hasten development 

 and increase yield. 



Mixed graftage, L. Daniel (Compt. Bend. Acad. Sci. Paris, 125 

 (1897), Xo. 18, pp. 601-001; also in Rev. Hort., 69(1897), Wo. 24, pp. 

 566-568, (ind Bui. Mens. Soc. Cent. Ayr., Wort, et Acclim. [Niee],37 (1897), 

 Wo. 12, pp. 229-233). — The author describes a method which he calls 

 mixed graftage (la greffe mixte), and reports some experiments com- 

 paring it with the ordinary method. The method differs from the ordi- 

 nary method in that a few shoots are allowed to grow permanently upon 

 the stock and are kept pruned sufficiently to prevent their seriously 

 checking the growth of the scion. 



By means of mixed graftage a successful union of a scion of the wild 

 cherry (Gerasus avium) with the cherry laurel (Primus laurocerasus) as 

 a stock was readily effected, a union which is considered very difficult 

 to secure on account of the widely different characteristics of the 2 

 trees, one having deciduous and the other persistent leaves. 



In order to compare the effect of ordinary graftage with that of 

 mixed graftage, 2 very unlike haricots, the large haricot of Soissons 

 and the black Belgian haricot, were used. In case of both methods of 

 graftage the black Belgian haricot was used as the scion and the large 

 haricot of Soissous as the stock. The grafted plants were grown 

 together with nongrafted ones of both sorts under the same conditions
