GRAPES.— (F«w). 



The fact will doubtless be recollected that, during the spring of last 

 year, a severe frost occurred, after the t^rowth of the young canes was well 

 advanced, which nearly or quite ruined the incipient canes. The injured 

 canes were allowed to remain; and many of the buds upon them subse- 

 quently developed new canes. These, together with the additional canes 

 subsequently produced from the old wood, soon multiplied the number of 

 young canes beyond the ability of the plants to produce strong fruiting 

 wood for the following year, rendering it highly probable that the better 

 practice would have been to entirely remove the injured growths, and 

 depend wholly upon new growths from dormant buds. Many of the 

 weaker canes were cut away when the error became obvious, although too 

 late to insure the best results. 



The crop of this year has apparently been considerably diminished from 

 this oause. 



The spray of copper sulphate (one pound in twenty- five gallons of 

 water), with which all dormant plants were treated, was applied to grapes 

 on April 15th. 



On June 12th, grapes were sprayed, to prevent anthracnose, with a 

 solution of one pound of copper-sulphate in 200 gallons of water. 



On July llth to 21st, finding indications of mildew, grapes were again 

 treated with a solution of one pound of copper -sulphate in 250 gallons of 

 water. 



Mildew proving unusually persistent, the latter solution was again 

 applied on August 4th and 5th, and again on the 13ch. 



No attacks of either fungi or insects have proved troublesome, beyond 

 those already specified. 



In the column headed Parentage, in the following table, the species of 

 the mother or seed parent is first given, and followed by the known or 

 supposed cross. In the determination of such parentage, the writer has 

 been very kindly aided by Prof. T. V. Munson, of Texas, who is generally 

 recognized as the leading expert in this country, so far as the botany of 

 the grape is concerned. 



In the great majority of cases, the actual parentage can only be inferred 

 from the characteristics of the resultant plant, or the tendencies mani- 

 fested in seedlings therefrom; it will therefore be understood that, in many 

 eases, conclusions are drawn from such premises.
