The language of the law presents some very interesting problems to those of us who have tramped the fields and valleys in search of nut trees producing better nuts than those already propagated, and it incidently brings into the patent practice a brand new requirement. The ablest patent lawyer in America might not know the difference between a bud and a graft, a layer or cross-pollination. I have frequently had some very able lawyers who visited my farm and had their attention called to a pecan tree grafted onto a hickory, ask what kind of nuts it would bear. Of course when they ask such questions as that I promptly change the subject and begin to talk about the weather or something else; I certainly do not try to educate them in the fundamentals of tree propagation. It will also require specialists in the patent office who likewise know something of horticulture and reproduction methods of plants. It will also be noted that the law excludes tuber-propagated plants. The Committee report states that: "The bill excepts from the right to a patent the invention or discovery of a distinct and new variety of a tuber-propagated plant. The term "tuber" is used in its narrow horticultural sense as meaning a short, thickened portion of an underground branch. It does not cover, for instance, bulbs, corms, stolons, and rhizomes. Substantially, the only plants covered by the term "tuber-propagated" would be the Irish potato and the Jerusalem artichoke. This exception is made because this group alone, among asexually reproduced plants, is propagated by the same part of the plant that is sold as food." It will be noted that there is quite a spread, however, between the exact language of the law and the Committee report, for example: under the law it would appear that a dahlia might be excluded, and it also raises the question, under the language of the law, as to many of the root plants, such as peonies and others. Obviously, Congress did not intend to exclude plants such as the dahlia, peony and others, as evidenced from the excerpt in the Committee report above quoted, and whether the matter of the production of a new dahlia by cross-pollination and tested out through the growth of the bulbs, can be made to harmonize with the language of the law is the question. The Committee report says that tubers mean only "Irish potatoes and Jerusalem artichokes." It always occurred to me that the sweet-potato is also a tuber, but the Committee report apparently attempts to exclude it. There are any number of interesting questions that occur to those of us who are fortunate enough to have some knowledge of the law as well as a few fundamental principles of horticulture, but in spite of whatever weakness the law may or may not have, it is undoubtedly a step in the right direction, and meets a long-felt want. The Secretary of Agriculture said in his letter to the Committee:
