Colure is quite common, much more so on sandy soil. Sunscald is frequent but not bad. I saw quite a number of grapes scalded on every vine, but not enough to warrant any special measures to be taken as a protection. The grapes have during this and last year ripened by the first days of September, but it is generally much later, or at about the 10th of September, when the vintage usually commences. The picking was, until last year, done by white labor, but the same was so very difficult to obtain that Chinese were then employed. They gave satisfaction to some, while to others not. Some of the principal growers are this year (1889) going to employ Chinese help at $1.25 per day, at which price they board themselves. _The Crop._--The grapes are dried on redwood trays made of sawed redwood shingles, three-eighths of an inch thick. The trays are made two by three feet. The best growers are this year going to assort the grapes when putting them on the trays. This was never done before, but will be of great advantage. A tray will average eighteen pounds of fresh grapes, which will take about one month to dry,--never less than three weeks. There is but little second crop, generally none that can be saved. September is the warmest month, or else the grapes could not be dried. At a temperature of 103 degrees Fahrenheit, it was found that grapes scalded or cooked while on the trays. This is, however, very rarely the case. From ninety-five to one hundred degrees is considered the best temperature at which the best raisins are made. The sweatboxes used formerly were two by three feet and ten inches deep; but of late eight inches and six inches in depth is considered the best, on account of the facility with which they can be handled. As to packing, many advocate twenty-pound boxes, that are only four and one-half inches deep, contending that they will hold twenty pounds of loose raisins. Few Dehesas are put up, the general brands being three crown London layers, and three crown loose Muscats. Some are also put up in fancy paper boxes. This year the valley has two packing companies, who buy raisins in sweatboxes, and pay from four to five and a half cents per pound. The yield per acre is from two to three tons of green grapes, I should say this year nearer two than three tons. I saw, however, some that would average five tons per acre, but this land was favorably situated in a moister place than is generally found in Sweetwater valley, and the vines were yet growing on August 21st. I heard of much greater yields, so extraordinary indeed that they are not likely to return again. From five to seven tons to the acre is a really rare yield, even on the best land, where the water is within six or seven feet of the surface. This shows me conclusively that judicious irrigation would materially increase the crop, and greatly improve the uniform size of the berries. The profit on an acre of bearing Muscat vines is from fifty to one
