A correspondent of the Ohio Farmer, F. R. E., (it will not be difficult to guess who that is,) describes the following new grapes. . The Mottled and the Mary we have alluded to in a former number, the latter, however, not having been ripe. We should like to see them again. It would be nothing singular to receive the Isabella from Germany, for it has been grown and propagated there many years. F. R. E. remarks as follows:

"Among the many valuable grapes now before the public, the following have claims to favor equalled by very few. One, the Aiken, has been some years grown as a superior and early Isabella, but its description has never been printed; the other two are entirely new, and thus far have not been offered for sale.

The Grapes #1

We present our readers in the present number with much matter regarding grapes, a topic of increasing importance. Mr. Charles Downing's article will be read with interest, and in connection with it we refer to the reliable catalogue of Dr. C. W. Grant, of Iona near Peekskill, New York, who has a very valuable stock of grape vines, for the supply of dealers and growers. Dr. Grant now brings out the Anna, which we have twice tasted, and we think well of it, though for excellence, independent of growth, our own choice is as follows: Rebecca, Delaware, Diana, Clara. Anna may prove superior, as it gets more growth and age. Of the Diana Dr. Grant says:

"The 'stock' (constitution) of the vine has been yearly developing, and has now attained an excellence that at first the most sanguine scarcely hoped for. It has generally been considered a feeble grower, as well as small and unproductive; and from unfavorable circumstances such it appeared at the beginning. For a large price I procured in the spring of 1850, twenty-five plants which were so small and languishing in appearance, as to be regarded with despair, rather than pitying hope; and for two years, under the most tenderly cherishing nurture, my success was not very encouraging, even with those that survived; for with my best care, life had let go its feeble hold of some of them. After they became strong enough for layering, the progress of development was very encouraging; and each year has marked a decided improvement on the foregoing up to the present; and this has afforded the most gratifying result of all. For, notwithstanding the very unfavorable character of the season, not only have my own vines given better and handsomer fruit than ever before, and this uniformly on all my vines - those the second year from planting giving fine crops, and those planted this season (one year old at the time of planting) have given excellent specimens of fruit; and those to whom I have sent large vines, have expressed their gratitude to me for the same performance of their vines.

This, although quite satisfactory, is far from the full capability of the Diana, for every well-treated vine improves for ten years from planting".

We find that a postscript to Mr. Downing's article has been omitted. It is as follows:

P.S. - I will here state that I have no vines for sale, and am not connected either directly or indirectly with any Nursery establishment. I say this, because it appears not to be generally known that I discontinued the Nursery business some five or six years since. - C. D.
