The peach foliaj^e is very susceptilile to injury from copper sohitions, which must, 

 therefore, be applied at from one third to one fourth the strength used upon the apjile 

 and pciir. 



E.vperinirnts irifh (jrapes and peaches (p]). 32-30). — Of 120 varieties of 

 grapes grown in tlie station vineyard, 105 fruited in 1891. Very few of 

 tlie new varieties are found e(|ual totlie standard sorts for general pur- 

 poses. Concord, Worden, Moore Early, Delaware, Brighton, and Lady 

 are reeomniended for general planting in ISTew England. Among new 

 varieties, Berckinann, Lindley, Massasoit, Kocliester, Salem, Wilder, 

 and Winchell (Green Mountain) have shown tliemselves to be promising. 

 Ten of the new varieties are briefly described. 



To test the keeping' ([ualities of tlie many kinds of grapes grown, small ([uaTitities 

 of each were placed on trays and put into the fruit rotmi about October 1. Those 

 that showed the poorest keeping (qualities were Ann Arbor, August Giant, Chainj)ion, 

 Concoj'd. Early Victor, Eaton, Hayes, Jancsville, Lady, Martha, JVIoore Early, Nectar, 

 Niagara, Pearl, Triumph, and Worden. Those keeping u]> to Man-h 1 in fair condition

Of 18 varieties of peaches which fruited at the station in 1891, Cool- 

 idge, Old Mixon, and IStnni]) — white fleshed varieties — and Crawford 

 liate, Foster, Reeves Favorite, Wheathmd, and Crosby (Excelsior) — 

 yellow fleshed varieties — were the most productive. 



0])servations on peach bnds showed " that tlie buds were largely 

 destroyed before the middle of December and generally before the tem- 

 perature had reached zero or a few degrees below. When it has reached 

 from 15° to 20^ below the buds have nearly all been killed." The per 

 cent of buds of 10 varieties found killed March 1 during the past 3 

 yeais (1890-92), as tabulated, iiuticates considerable difference in the 

 hardiness of dilTereiit varieties. 



Exix'rimcats daring 1 years (1888-92) in protecting the buds by bend- 

 ing dowii the trees and covering thi-m with mats (obtained from straw- 

 hat factories) and otiier light material indicate that when the covering- 

 is not too heavy it prevents the destructii)n of the buds and that this 

 treatment does not injure the trees.

 on an unsuccessful attein])t to top-bud Siberian crab apple trees with 

 the Williams Favorite a])ple. The results are illustrated. 



Girdling grapevines (pp. 37, 38). — An account by J. Fisher of exj)eri- 

 ments in continuation of those report(;d in Bulletin No. 13 of the sta- 

 tion (see Ex])eriment Station Record, vol. in, ]». 24). Data are given 

 which indicate that girdling (in 1890) weakened the vines and reduced 

 their productiveuess the following season.
