138 • MILDEW. 



Union Village, tat our observations have not fully satisfied us 

 that this is the case. It is an exceedingly coarse, vigorous grow- 

 ing variety, not any more hardy than the Isabella, with exceed- 

 ingly large, compact, weU shouldered bunches, and berries fully 

 as large as those of the Black Hamburgh ; black, juicy, with 

 very little pulp, and a pleasant, mild, vinous flavor. It ripens 

 usually a little before the Isabella. 



Eebecoa. — Is not suited to general culture, thriving weU 

 only in a few favored localities. It is a white Grape, of good

 is not vigorous, nor capable of enduriag extremes of cold. 



Saibm. — Rogers' No. 22. — One of the best of the red-colored 

 Grapes of Mr. Eogers' Seedlings. A healthy and vigorous vine, 

 bearing abundantly, having good sized, short, but compact 

 bunches, and large, round, dark red berries, which are juicy,

 Concord. It is said that this Grape will keep weU through the

Wilder — Rogers' No. 4 — ^The best black grape raised by 

 Mr. Rogers. The vine is vigorous, healthy, and productive. 

 The bunches are sometimes large, shouldered, and compact ; ber- 

 ries large, with very little pulp ; sweet, juicy, and rich ; ripe 

 with the Concord.

 sequence of an enfeebled condition of the vine. These parasitic 

 plants do not find in the healthy vine the conditions favourable 

 to their development. It is when the vine has received some 

 shock, has become in some degree unhealthy, that these para- ,
