The raisin made from the Muscat of Alexandria looks smaller on account of its oblong form, and is less suited for facing the boxes, but as to other qualities, such as taste, sweetness and color, there is no marked difference between these two varieties of Muscats. All varieties of Muscats set better in moist air than where the air is very dry, and the moister air tends to better develop the bunches. This explains why, in isolated vineyards in the interior, the bunches are never so large as where a large number of acres of vines have modified the often excessive dryness of the atmosphere. As to the relative distribution of these two varieties of Muscats in our State, it may be stated that the former is not based upon any particular adaptability of the respective varieties to the localities where they are grown. The Muscat of Alexandria is the older variety of the two, probably both in Spain as well as in California. To Valencia in Spain it was brought by the Moors from Africa, or possibly from Alexandria in Egypt. The Gordo Blanco again appears to be a native Spanish variety, especially adapted to the warmer region of Malaga or Southern Spain. The Gordo Blanco is the principal grape of Malaga; the Muscat of Alexandria is the one grown in Valencia and Denia and also in Smyrna in Asia Minor. In California the Gordo Blanco is found around Woodland in Yolo county, throughout the San Joaquin valley, and in Fresno it is the favorite and almost exclusive Muscat grape. The Muscat of Alexandria is grown in Solano county and elsewhere in Northern California, while it is the exclusive grape in Riverside, Redlands, Orange county and El Cajon, and probably elsewhere in San Diego county or Southern California generally. The Muscat of Alexandria was imported by Colonel Agoston Haraszthy in 1852 from Malaga, and by D. M. Delmas some thirty-eight years ago from France. _Huasco Muscat._--This variety (pronounced Uasco) resembles very much the Muscat of Alexandria, of which it is probably a seedling, and was introduced into Chile by the Spaniards soon after the conquest. According to Professor E. W. Hilgard, this variety sets better than the Alexandria, and on that account deserves to be cultivated. It is strange that no attempts have been made in this country to grow it on a larger scale. The Huasco is undoubtedly one of the most interesting grapes, and the fact that it produces the most expensive raisins in the world should be a sufficient inducement to our California growers to at least study the variety closely. I should think that El Cajon valley would be the proper locality for it in this State.
