Before I close, I should like to call attention to a plant, endemic in eastern North America, whose tubers were called "ground-nuts," or "Indian potatoes" by the early colonists. The latter name caused the plant to be mistaken by certain early writers for the white potato, which was unknown in North America in early colonial days, but which was confused with the ground nut on account of the resemblance of the descriptions of the two plants. The white potato, _Solanum tuberosum_, was discovered in the Andes of South America by Cieza de Leon; it was quite unknown in North America or in the West Indies in the days of Sir Walter Raleigh and Sir Francis Drake, both of whom have erroneously been given the credit of introducing the potato into England. The "potato" which they observed in the West Indies was not _Solanum tuberosum_, which we now call the "white potato" or "Irish potato," but a very distinct plant, _Ipomoea batatas_, which we now call the "sweet potato," but which in early days was known as the _batata_ or _potato_. The error which has become widely spread, can be traced to John Gerarde, the first author to publish an illustration of _Solanum tuberosum_. In his celebrated _Herball_ he declares that the potatoes figured by him were grown in his garden from tubers which came from "Virginia, or Norembega." It is quite certain that this statement was untrue, and that, as certain English writers have already suggested, Gerard "wished to mystify his readers." Whatever may have been his motive, the error became widely spread. Even Thomas Jefferson was led to believe that _Solanum tuberosum_ was encountered in Virginia by the early colonists, and Schoolcraft declared that its tubers were gathered wild in the woods like other wild roots. The Indian potato of the early colonists is still abundant in "moist and marish grounds," as described by Herriot. It is a tuber-bearing plant of the bean family, and is known botanically as _Glycine apios_. But I fear my talk has become too discursive, in turning from nuts to ground nuts, and from ground nuts to potatoes; but the subject, bearing as it does on the origin and history of cultivated plants, is one which has great attraction for me, and I hope it may have been of interest to the members of this association. Professor C. P. Close, Pomologist, U. S. Dept. of Agriculture, spoke as follows: MR. CLOSE: The subject I had intended to speak on was "Extension Work in Nut Growing." Many of you know that I am putting in most of my time on the fruit end of extension work, but I am also doing some extension nut work. I was hoping that there would be representatives from many of the states here, because I wanted to encourage them to get in touch with the state extension men, to work up interest in nut culture.
