Fruit ripened the first week in September, and the wood fully ripe to tips by the first of October; exposed to twenty-nine and a half degrees below zero, as indicated by a registering thermometer. Uninjured.

The following I class as half hardy. The fruit for 1861 is entirely killed; but ordinarily they stand our severe winters, and bear fruit. I have found, however, that whenever this class of vines are laid upon the ground and covered with earth, the fruit of the following season is fine, and ripens several days earlier than if exposed on the trellis during winter: Isabella, Catawba, Diana, To Kalon, Union Village, Garrigues, American Hamburgh, Hyde's Eliza. My advice to cultivators north of Maryland is, to cover these varieties every fall.

The following varieties I find were covered purposely, or by accident, and of course are in good order now: Delaware, Anna, Rebecca, and Lenoir.

[The above statistics are of much value, and we should feel obliged to any of our subscribers who can furnish carefully collated observations on the same subject. We have seen the "oldest inhabitant," and he told us confidentially that the cold was the greatest he had experienced during his long life. He said,, moreover, that the weather was " very queer;" by which he no doubt referred to its extremes and sudden changes. The weather last fall was unusually unfavorable for the ripening of wood, and the winter exceedingly trying; under the operation of these two causes, the destruction has been great. When it is understood that it is not the simple freezing that does the mischief, it will be easy to comprehend why Mr. Cornell's vine on the north side of his barn escaped. There are some kinds in your list that might have been injured without much harm to any body. In a locality quite as cold as yours, and much more trying, we recently examined a number of kinds, and found uninjured, the Diana, Delaware, Concord, and Hartford Prolific. The Isabella, Catawba, and Rebecca were killed " root and branch".
