Soils and Ripening.
—The soil here is the very best, and I doubt if the same fine quality of soil is found anywhere else in California over the same extended territory. I ride for miles and miles, everywhere the finest and richest loam of a gray color, sometimes a little drawing towards slate blue, sometimes again towards yellowish. It is immensely rich, and can hardly be improved. There is, however, especially near Orange, a different kind of soil consisting of the sand loam, but intermixed with very coarse gravel. This soil is warmer but consequently not so rich. The grapes ripen on it two weeks earlier, but yield only one-half as much as those on the richest loam along the creeks. The vines planted here were alone the Muscat of Alexandria. Strangely enough I find no traces of Sultanas or currant, which latter, it seems, should be especially adapted to the coast climate.
The Vineyards.
—In planting a vineyard, rooted vines were seldom used. Cuttings grew so readily and so well that they were much preferred. I am told that five per cent loss was unusual. It must be remarked that the moister is the air the better it is for any kind of cuttings. The moisture sustains and nourishes the wood while it is making roots. As to distances, I remarked nothing new. Eight by eight or eight by ten feet seems the generally adopted way. The nature of the soil and climate make higher cultivation a necessity. McPherson Bros., who packed the largest quantity of raisins and owned the finest vineyards, told me that they plowed and cross-plowed and cultivated from fourteen to sixteen times every season; in fact they never ceased working the ground. The pruning was begun in December, or as soon as the leaves began to turn and fall. To begin with, only a few spurs were left on every vine, and on every spur three eyes, including the bottom eyes, but experience taught that that way was not the very best. Gradually more space was given the vines, and now from fifteen to twenty spurs to a vine in full bearing is considered proper. Summer pruning is only practiced in some of the vineyards where the ground is quite wet. The most profitable vineyards were irrigated. The nearer the coast the more moisture there is in the soil. Thus three miles west of Santa Ana the ground is always moist enough to grow grapes, but as we come nearer the foothills to the east, the moisture is farther down. At Tustin, Orange, and especially at McPherson, irrigation was practiced in all first-class vineyards. Some were irrigated in the winter only, and this was considered the best; others again were irrigated also once in summer,—a practice the best vineyardmen considered unnecessary and even injurious. I found land near the town of Santa Ana moist one inch below the surface, where no irrigation had even been practiced. Sulphuring was used everywhere to counteract the oidium. For this purpose powdered sulphur was dusted through the vines as soon as the grapes were as large as small shot. From three to four sulphurings were used every year with a week between each. Sulphuring for the colure or dropping of grapes was not known; in fact I am informed that this colure was seldom known. Besides mildew, there are few enemies to the vine here. Grasshoppers, leaf-hoppers and grape moths have never been known to molest the vines. When the late vine-plague struck the country the vineyardists were entirely unused to fight any enemy of the vines besides the oidium. Sunscald of the berries was not known.
The Crop and its Curing.
—The grapes begin to ripen in the end of August, say about the twenty-fifth, on the gravelly soil, but on the cooler and richer bottom land very much later, or about the middle of September. The harvest then begins; the grapes are picked on trays two and a half by three feet and placed to dry in the sun; the drying takes two or three weeks or more, and is accomplished with some difficulty. Two years the grapes had to be carried out to the Mojave desert, to be dried there. The trays are placed among the vines in such a way that the trays from three rows are placed in one. To protect them from the fog and dew, they are covered with canvas. This is done in two ways. One way is to put small pegs on one side of the trays. The long canvas is furnished at intervals with rings, which are slipped over the pegs and thus held steady on one side. In the daytime the other end of the canvas is simply thrown back over the pegs; in the night-time the canvas is again turned over the trays, resting directly on the grapes. The other and better way is to run three wires along the row of trays, one on each side of the trays. The canvas is furnished with rings on each long side, which are made to run on the wire. The center wire is run a little higher up, and here and there simply supported by posts. It takes comparatively little time every evening to run the canvas along the wires and cover the trays. The expense is considerable, both in furnishing and preparing the canvas, and in maintaining and operating it. The peculiar climatic conditions of the district, however, necessitate some such contrivance for the drying of the grapes. The vines seldom bear a second crop of any importance. Sometimes in October the district is visited by a warm and dry desert wind called the Santa Ana wind. It comes from the cañon of the Santa Ana river, and originates, no doubt, in the Mojave desert, and rising high up in the air is again precipitated over the hills on the lowlands towards the ocean. This Santa Ana wind is always welcome. It hastens the drying of the grapes just as the Terral or land winds from the plains of La Mancha hasten the drying of the grapes of Malaga in Spain.
Yield and Profits.
—The yield is quite small on the gravelly soil, at the most being three tons of green grapes to the acre, on richer land from six to seven tons, and in rare instances ten tons to the acre. I heard of one vineyard where the owner had sold from twenty acres of Muscatels thirty-three tons of raisins and fifty-six tons of green grapes, equal to about 155 tons from the lot. Another lot of three-year Muscatels bore ten tons to the acre,—indeed a very unusual yield anywhere for Muscatels. I hear reports of some wonderful yields and high profits, but am informed by the most experienced and trustworthy that $125 per acre is an average profit which can be relied upon year after year. The first Muscat vines were planted near Orange, now the station of McPherson, about 1873, by McPherson Bros. The acreage in grapevines in the Orange county district was about 8,000 acres; but probably over half of it is wine grapes. The highest output of raisins was 170,000 boxes of twenty-pounds each.
