Four years after Mr. Sexton of southern California had planted this sack of walnuts from San Francisco, Mr. Felix Gillet of Nevada City, in northern California, began the introduction of French walnuts both by seed and scions. Out of his efforts and those of others who subsequently joined him, developed the walnut industry of northern California, which now bids fair some day to equal that of the lower part of the state. The famous French varieties of Franquette and Mayette were introduced by Mr. Gillet, and from seedlings of his growing evolved the Concord, the San Jose, and no doubt the Chase varieties.[1] A nut which probably has received equally as much, if not more, attention at the hands of experimental planters in this part of the country is the chestnut. Just when the introduction of foreign strains began, history seems to have failed to make clear; but according to Powell[2] general dissemination in the Delaware section began with introductions by Eleuthers Irénée du Pont de Nemours, made at about 1803. It is said that some of the original trees planted at that time near the present site of the du Pont Powder mills by Mr. du Pont, still survived when Mr. Powell recorded their history in 1898. The spread of both European and Japanese chestnuts and their general trial throughout the Eastern States has been narrated at former meetings of this association. The chestnut blight, discovered on Long Island in 1904, after it had apparently gained several years' headway, and which now seems fairly certain to have been introduced from Japan, has so monopolized the attention of orchardists, foresters, landscape gardeners and others interested in the chestnut that for the time being little is being done with it, other than to study and discuss this disease. What the final outcome will be no one can predict, but it is not improbable that our pathologists will discover some practical means of control, or that a natural enemy to the blight will appear. Nor is it unlikely that immune strains of chestnuts, either native or foreign, will replace our present groves and orchards, in case other efforts fail.
