_General Remarks._--The San Joaquin valley is well adapted to raisins along its whole length almost, but especially in its central and southern parts. The farther we go south in the valley, the drier is the climate, and the less is the rainfall in the autumn of the year, both conditions favoring the curing of the grapes. The present raisin center is around Fresno City, where over twenty-five thousand acres are planted to raisin grapes, principally Muscatels; but from this locality the industry has been constantly spreading, until at present the other counties in the valley, viz., Merced, Tulare and Kern, can show a good acreage of young vines. Next after Fresno, Tulare county produces the largest quantity of raisin grapes, and produces raisins of the very highest quality. The principal raisin vineyards in that county are situated in the Mussel Slough district, on the rich bottom lands formed by the former delta of Kings river; of late, the planting of raisin grapes has extended to other parts of the county as well. In Kern county few old raisin vineyards exist, the oldest one being situated on the Livermore ranch, being a part of the Haggin and Carr tract. Several hundred new acres have been planted there this spring, especially in the Rosedale, Lerdo and Virginia Colonies, as well as on the plains near Delano. I need here hardly say that the raisins of Fresno, Tulare, Kern and Merced counties should be all classed together, as the climate in these various localities is one and the same, with only a slight and gradual change as to rainfall as we go south in the valley. If there will, in the course of time, be found some difference as regards quality in the raisins of these various localities in the San Joaquin valley, this difference will not be due to any great difference in the climate, but to the variety of soil on which the grapes are grown. The raisins are only grown on the level lands, situated from three to four hundred feet above the sea.
