_Location and Acreage._--San Bernardino county, California, is entirely an inland county, sheltered by low and high hills from the ocean. Fogs and dew are rare, in places unknown, and the county offers unusual advantages for raisin-growing. The vineyards are widely distributed through the county in different localities or raisin centers, all of which are greatly similar as to climatic conditions, except as regards altitude. The San Bernardino vineyards are the highest elevated above the sea of any in California. Below will be found a list of the raisin centers in the county, with the number of acres and their altitude above the sea. It must be understood that each locality has a large extension as regards altitude, and varies in many instances several hundred feet; this fact being indeed a characteristic of the San Bernardino county vineyards. The raisin centers in San Bernardino county are: Riverside, 1,500 acres. Altitude above sea, 900 to 1,000 feet. Redlands, 800 “ “ “ “ 1,200 “ 1,600 feet. Highlands, 400 “ “ “ “ 1,500 feet. Ontario, 500 “ “ “ “ 983 “ 2,350 feet. Cucamonga, ---- “ “ “ “ 900 “ 1,500 feet. Etiwanda, 700 “ “ “ “ 1,200 feet. There are several other localities where raisin vineyards are found in smaller quantities, and it is safe to estimate the number of acres in the county at over five thousand. Nearly all these vineyards are situated on mesa lands, by which is meant the lands situated between the river bottoms and the foothills. As a consequence, the surface water is never near the top, but generally far down, and even continued irrigation would not be liable to raise it much higher, as the water will as rapidly drain off through the substrata, which generally consists of sandy soil and gravel. The land is in fact well drained, and differs in this respect from the plains of the San Joaquin valley. In Riverside, the surface water is from thirty to fifty feet down, and only in one or two vineyards situated deep down in the _arroyo_ is the surface water as shallow as ten feet. These latter vineyards are never irrigated. In Redlands the surface water is at an average of thirty feet on the mesa lands. In Ontario the surface water is even deeper, and found at from seventy to eight hundred feet, and the shallowest water in the district is, according to Mr. W. E. Collins, twenty-five feet below the surface. It is the general belief in the San Bernardino district that deep water is necessary for, or at least beneficial to, raisin grapes, and that shallow surface water is conducive to all kinds of diseases. In this I cannot agree, as contrary to my own experiences and to the experiences of the Spanish growers.
