CUM ATE. There is a great contrast between the climates of western and eastern Washington, owing to the fact that the Cascade Range con denses the greater part of the moisture in the west winds and shuts out the tempering influence of the sea. In western 'Washington the climate is equable, with a mean temperature for Janu ary of 39° and for July of 62°, while the minimum is generally between 10° and and the maxi mum about 95°. In eastern Washington the mean for January is 30° and for July 74°. while the extremes range between 112' and 30° below zero. 'Western Washington has a humid atmos phere with an annual rainfall ranging front 54 inches at Olympia to 132 inehes at Clearwater, on the Pacific coast. In some years the rainfall on the coast may be even more than 150 inches, a quantity exceeded in few' places on the globe. The average normal rainfall for the whole of eastern 'Washington is 16 inches, and except on the higher slopes in the north and southeast, it is insufficient to support agriculture without ir rigation. In the south central part of the State
the average is less than 10 inches. Another cir cumstance unfavorable to agriculture in the east ern section is the fact that throughout the State by far the greater amount of precipitation occurs during the winter months. Thus at Clear water the normal precipitation for January is 20 inches, while in July it is only one inch. The snowfall is head• on the western mountains, but in eastern Washington it is light, and the warm chinooks often evaporate it completely without wetting the ground. Blizzards and tornadoes are unknown, but thunderstorms occur at long intervals.
