condition. Although the trees suffered a temporary check from this 

 cause, new and healthy foliage soon appeared and growth was resumed. 



The peach borer {^geina exUiosa), was looked after during last spring, 

 but none were discovered. Another examination in September brought 

 more or les§ of them to light; the greater number occurring, as seemed to 

 be usually the case, on the lightest soils. 



GRAPES, Vitis. 



Of these, forty-three varieties were planted in the spring of 1888; the 

 same number in 1889, and forty in 1890 — a total of one hundred and 

 twenty-six varieties. Of these, thirty-eight varieties are black or nearly 

 so; thirty are classed as red varieties, and thirty-four are white, yellow, or 

 green in color when mature. Of nineteen varieties, not yet fruited here, 

 the color is not known. 



Of those planted in 1888 and 1889, thirty-nine varieties have shown more 

 or less fruit this season, and the following is a tabular list of such, with 

 results of the present year's experience, together with such further partic- 

 ulars as are deemed warrantable from that of the past. 



It should be noted, however, that there is unavoidably more or less 

 uncertainty as to season of ripening, and perchance as to the estimate of 

 quality also, since it became necessary to gather the fruit of several 

 varieties before full maturity, to avoid their entire loss by pilfering. 



Insect attacks have not proved troublesome upon either plants or fruit 

 this season. 



Late in the season, numerous small, dark spots appeared upon the 

 foliage of several varieties, due, probably to mildew. No injury to the 

 fruit was observed, although, when gathered, slight attacks of mildew were 

 discovered upon the stems of a few clusters of Brighton. 



Many of the varieties here tabulated were originally disseminated under 

 numbers appended to the name of the originator or introducer, and (as in 

 the case of the Rogers hybrids) a very common practice has been to 

 retain them, attached to the name, as subsequently given. As these are 

 no longer needed, they are omitted.
