Professor Lake: I may say that the western knowledge of the walnut is based very largely upon the character of the Santa Barbara Softshell, and the people in the West are fully satisfied that the Pacific Coast walnuts are the best in the world. I am thoroughly of their belief, too. I agree thoroughly with the doctrine that we have got to improve our own varieties, and that is being done in the best way that we know at present,—by cross-fertilizing and growing the seedlings. A number have been developed the past few years. It is very true that the general public's taste, however, is not up yet to the connoisseur's in this matter, and I am satisfied that the ordinary grade of walnut is going to meet the public demand for a long time yet. The Santa Barbara Softshell will sell to the American public for good profitable prices for some time, and in the meantime, the men who are really wideawake and have a knowledge of the situation are going to endeavor to improve the home strains. I can't see that we can hope for very much from France, for during the last two years the real Mayette of France has been imported, because we have trees bearing in Santa Clara Valley a Mayette as near like the Mayette of Europe as it is possible to make them. The French have not been particularly anxious for us to get their best strains.
President Morris: In this connection, let me say I have seen Mayette, Chaberte, Parisienne,—the best European walnuts—growing in this country, and in this country they do precisely like the best European grapes,—that is, they give us a different product. Imported grafted stock will take from our soil those elements which make an astringent, tough, insipid nut. We have got to recognize it. Don't let us fail to go on record as calling attention to that fact. That means if we import the very best European kinds and plant these, we are going to have the same records as with grapes.
Professor Lake: This matter of quality is of considerable moment to the growers out there. Last year I took occasion to write five of the leading dealers in New York, like Parke and Tilford. They said in their letters of reply, "We consider the quality as varying from season to season. Some seasons we get the California product better than the European product; other seasons it is just the other way." It leads me to think seasonal variation has a great deal to do with the walnut, possibly. In some cases even the large dealers are not yet agreed that the American product is not yet good enough for the American market.
President Morris: Shall we say that nuts for the connoisseur should not be bleached?
Professor Lake: Modern bleaching consists in running the nuts through a current of salt. It is applied in such a way that it does not do any injury whatever to the flavor or the kernel, unless possibly salting the kernel in cracked nuts would be considered injurious. The bleaching is beautiful. They are not over bleached. They use six pounds of salt to a thousand gallons of water, and run a current of ninety-five volts. It is sprayed on to the nuts as they pass through a revolving cylinder, the spray coming on in a fine mist. As they pass over the cylinder, they are graded and ventilated, and put into sacks. That is after they have been dried. They are ready in about twenty-two hours to be sacked and delivered. The old method of processing in soda and lime and sulphur certainly did injure them.
Mr. Pomeroy: I am just a short distance from Niagara Falls and Buffalo. When any of you are in that section, I would like to have you come and see my trees. There are the seven year old trees my father started, and the orchard is of five or six acres. Some of the seedlings are in bearing now. I have a good many black walnuts in nursery rows, and I am going to begin grafting and budding. One thing I came for was to get information in regard to budding and grafting. In regard to the caring for the trees, it is a great pleasure to watch a tree grow and get it in shape.
Professor Craig: It seems to me that out of the very interesting discussion we have had on this question of the Persian walnut, and out of the discussion which has arisen from the papers of Mr. Littlepage and others on native nuts, we have obtained some very general principles which should be emphasized at this time. The one large principle that I want to call attention to is the principle which says that, in order to develop fruits—and we will include nuts in that general group—which shall be useful to the American public, we shall have to develop them under American soil and atmospheric conditions. In other words, the importation per se of European stock of whatever kind is altogether likely to meet with failure. This is the history of American fruit growing from the beginning. The very first beginning of fruit culture in this country was the importation of European fruits, and these uniformly failed. Success came when American colonists began to grow American seedlings. The fact that these have prevailed is shown by the percentage of American fruits the large orchardist produces at the present time. Today nearly ninety-nine per cent of our apples are of American origin. The condition of today means success; the condition of a hundred years ago meant failure.
In this Persian walnut business, I think success is going to come to us through such work as Mr. Pomeroy and other interested amateurs are doing throughout the country, in selecting a good type of seedling here and there and growing seedlings from it. This homely old method of producing new types through seedling selection is, I think, going to do a great deal to ameliorate conditions the country over. I simply wanted to impress that idea, that if we nut growers are going to do something to help the nut interests of the country, we can do it by planting nuts and selecting nuts from the best types, again taking the best nuts from the best types and planting them; thus by keeping on selecting, we shall win success in the future.
