_Climate._--As regards temperature, there is some difference in the various districts. A true comparison between them and other districts is almost impossible, as the signal service thermometers are placed at unequal heights above the ground, and in localities with very different characteristics. It can, however, be said that the winter climate of the district is much milder during the winter than that of the plains of the San Joaquin valley, and very similar to the Orange county and the San Diego districts. In Riverside and Redlands, the thermometer seldom reaches one hundred and nine degrees Fahrenheit in the shade during the summer, and in winter seldom goes below twenty-four degrees Fahrenheit, while twenty-eight or twenty-seven degrees Fahrenheit is no unusual occurrence once every year, but is considered the extreme of the season. It may thus be seen that raisin vineyards and orange orchards may be and actually are grown side by side in every part of San Bernardino county, and this is a distinct characteristic of the district, which, however, it shares with Orange and San Diego counties. The warmest months are August and September, and October is generally fine for drying. So is November, and only twice (in 1885 and 1889) has there been any serious difficulty in drying the grapes. In two other years the crop has suffered slightly, but during the majority of seasons in the months of November there has not been any rain on the mesa lands, and it is this absence of fall rains which makes it possible for the raisin-grower to dry his crop without any other appliances than raisin-trays. Dew and fogs are very rare, and occur only very seldom during the summer months. When they do occur at this time, they are of but short duration, and last perhaps only from five to seven o’clock in the morning. In the fall of the year, in October and November, the desert wind blows warm and dry, and hastens the drying of the raisins. It may blow three or four times during the season, but has also been known to be entirely absent. The rain in the winter season is light, in Riverside twelve inches being an exceptionally wet season. From six to eight inches are the usual rainfall, while again the actual average for Riverside is six and one-fourth inches. In Ontario the rainfall in 1887 was 8.21 inches, and in 1888 9.23 inches.
