Wm. Sumner, one of our occasional correspondents from South Carolina, writes of a remedy for rot in the grape, as follows:

"I have in my possession a most important discovery which I propose to furnish applicants for a reasonable sum. It is a remedy for the rot in grapes, accidentally discovered, and tested with success upon the Catawba, Isabella, Herbemont, Madeira, etc., all of which rot badly in this climate. The Isabella has rotted so badly for years, that in many sections it has been cut down as a cumberer of the ground; while the Catawba, so valuable as a wine grape, has almost been abandoned, and one or two inferior grapes (the Clinton, etc.), that are comparatively free from rot, have been taken up and are now being cultivated as the wine grapes of the United States. This remedy will restore the Catawba to its place as the grape richest in glucose, and better adapted for making good wine without the addition of sugar than any other grape. The remedy is cheap, within the means of all who cultivate the grape, and can be applied, if need be, with any of the other fertilizers without injury to their properties. If we all had not been left so poor from the war, the remedy would have been given cheerfully to the public; as it is, it may restore us to a competency".

We confess we ourselves have little faith in any of these so-called remedies, but it is worth while before denying a point to prove one's denial, and therefore we hope to see this tested.
