GRAPES AND VARIETIES. 
479 
years, the summer average was 68 ^. From this I conclude 
that the Delaware and Concord may be safely planted in 
southern Wisconsin, and that the Delaware will ripen atGrreen 
Bay. While near large bodies ©f water, or on high altitudes, 
where the September mean temperature extends into October, 
without intervening frosts, the Isabella, Catawba, Iona and 
some of Eogers’ hybrids, with other late varieties, will suc¬ 
ceed. I, therefore, further conclude that no varieties should 
be extensively planted that require an aggregate summer 
temperature of over 8,000^ Fahrenheit, while near lakes, as 
at Madison, or on the bluffs along the Mississippi, or near Bara- 
boo, the late ripening varieties may be planted with expecta¬ 
tions of success. 
Among the thoroughly tested varieties, I would name the 
Delawares as at the head of the list, and the Concord as nearly 
equal to it. While the Janesville, with its early ripening wood 
and fruit, together with its productiveness, adapts it to a large 
range of country, where the late ripening kinds cannot be suc¬ 
cessfully grown. And in concluding, let me urge the horti¬ 
culturists of Wisconsin to observe the requirements of the 
many candidates for public favor, and thus determine what 
varieties to plant, that every family in our state may sit under 
their own vine and enjoy their refreshing fruits, using as not 
abusing, one of the best gifts of God to man. 
The essay being completed, the president announced that

• GRAPES AND VARIETIES. 
Mr. Adams remarked, that with him, in northwestern Iowa, 
Rogers’s Hybrid No. 8, ripened as early as the Delaware; and 
he thought much of that grape. 
The Oi'eveling. —Mr. Kellogg preferred the Hartford Prolific 
to the Creveling, for its fruit and bearing qualities. 
t 
Mr. Greenman said his Crevelmgs rotted badly on the vine. 
Mr. Adams said the Qreveling was of the first quality with 
him; though the bunches were loose, it fruited well.
