This is the title of a very pleasant paper in the Overland Monthly for May, by Mr. J. G. Lem-mon. Mr. and Mrs. Lemmon collected a quantity of the tubers of the native Solanum Fendleri and Solanum Jamesii; and these have been widely distributed for trial under cultivation. Mr. Lem-mon gives a history of the potato, and of these Arizonian forms in connection therewith; endeavoring to give all that has been written in regard to them. He singularly overlooks what is, perhaps, the fullest account of any trial made with them, given in the proceedings of the Academy of Natural Sciences of Philadelphia, for October 13th, 1874, and which work must be in the library of the California Academy of Sciences, and which paper gives the result of eight years trial with one of these species. It is there stated that this species when first planted had tubers about the size of a bullet, and had the bark or skin roughened by the free development of tuber cells. At the end of this period some had developed to tubers nearly as large as a walnut, oval, flattened, and with the smooth skin of a modern potato - and this, not by sowing the seed, but merely by selection from the tubers raised from the original tubers.

It is remarkable, seeing how much that communication to the Academy favors Mr. Lemmon's idea of the probable origin of the potato from the Arizona forms, that, in a chapter purporting to go over the whole ground, he should have overlooked this.
