I have just read the article by W., of Norfolk, Va., on disease of Marechal Niel Rose, but think he mistakes in assigning the cause to our severe climate.

Up to two years ago I think I had the finest single specimen for its age (three years) I ever saw; but now it is going in the way your correspondent speaks, viz: a knotty formation above the root. I had thought perhaps it was being on its own root; but last week, on a visit to the rose-houses of the late George Pum-pelly at Tioga, N. Y., I found the great Marechal Niel rose in a worse condition than mine - in fact, just about dead. It is a grafted rose that Mr. Pumpelly procured at Boston, about six years ago, and is a remarkable bush, having a trunk at the graft, I should think, some 18 or 20 inches in circumference. It is mournful to see such destruction; and can't some of our horticulturists find a remedy? I should state that the Pumpelly rose is all right below the graft, say 18 inches above the ground, but just above the Marechal Niel wood is affected as mine is, and as your correspondent speaks.
