Mr. Barron, of Chiswick, in a paper read recently before a learned society in the Old World, says on the authority of " Prof. Beal, of Agricultural College, of Lansing, Michigan," that a potato scion set into a tomato plant induced the latter to set small tubers in the axils of its leaves, as are seen sometimes on the tops of potatoes. The grafting of an Artichoke plant into a Sunflower caused the latter to form tubers underground. We do not believe that any tomato ever put forth tubers in the axils of the leaves as here stated. To the best of our recollection Professor Beal did not give this as fact in his lecture, but simply reported that he had "heard so".
