With regard to the quality of wine produced by any grape, it may be taken 
as a general rule that the best will be secured from the most southern climatic 
limit in which each variety will succeed. 
Although good wines have been produced from both of the species noticed, 
yet it is believed that the summer grape varieties ( Vitis Aistivalis,) are capable 
of furnishing them of greatly superior quality. Taking Norton’s Virginia 
Seedling as an example of this class, we find that its northern limit of excellence 
in ripening is much south of that required for the two formerly mentioned species 
and varieties; but, when properly matured, its wines are pronounced to be of 
first quality. There are, however, other varieties of this species still more 
promising, such as Lenoir, Herbemont, and Devereaux. When these are culti- 
vated in suitable localities in the States of Virginia, North Carolina, Kentucky, 
Tennessee, Missouri and Arkansas, they will furiish wines that, there is every 
reason to expect, will be unequalled by any that can be produced from any 
of the other species of American grapes, and will form, it may safely be 
prophesied, sooner or later, a means of largely increasing the remunerative 
products of these States. 
These distinctions of species, varieties, and the climates to which they are 
severally adapted, must ultimately be recognized as the basis upon which 
American wine culture is to be established, so far as it refers to American 
grapes. Wo.

Extracts from Correspondence. 
dackson Parish, La.—‘Since the worms ate up the cotton we are visited by 
worms destroying the oak leaves. They strip the trees completely, and hang 
in immense numbers from the limbs. They are large, black, ugly-looking 
worms, and our hogs eat them in such quantities that the meat tastes of them,. 
and emits a very bad smell when cooked. To eradicate the taste and smell it 
will be necessary to pen the hogs and feed them on corn for several months.” 
This caterpillar is probably Anisota (Dryocampa) senatoria, or a variety of 
the same which destroys the oak foliage in the middle States, and is in turn 
destroyed by an ichneumon fly. 
Bonaparte, Iowa—‘Have sent in a box, with ears of corn, worms supposed 
to be bud or heart worms, so called from their being found in corn-stalks, stems 
of horse-weed, &c. These were eating in the soft ends of ears of corn, but are 
darker than I ever saw them before. ‘They are always solitary, feeding alone.’” 
One of the worms sent was an Agvotis, or cut worm, and the other Helothis 
armigera, or corn worm of the middle States.. The worm mentioned as feeding 
in the horse-weed is probably a Gortyna, as they feed generally in the interior 
of stems of various plants. It is unusual to find an Agrotis on corn ears, as. 
they generally feed at the roots of plants. 
Albemarle, North Carolina—H. J. Kron, esq., gives discouraging reports 
about the destruction of grape vines in that region by Algeria polystaeformis. 
The larva of this insect working underground mines and destroys the vine 
roots, and being shielded by the bark defies the action of remedies for its. 
extermination. 3 
Mr. Kron states that the seuppernong alone resists the attacks of this insect, 
and thinks that grafting other varieties on this root is the only remedy in the 
infested districts. 
More recently a correspondent in Cincinnati writes that a new enemy has
