The soils of the county are largely sedimentary, having been washed
down from the mountains for ages, assisted by the decomposition of
vegetable matter accumulated through centuries. In the valleys, where
most of the farming is being done, these soils produce remarkable
crops under the influence of the charming climate the county affords.
The rainfall in the eastern part of the county is moderate, but
ample for all purposes; the average rainfall is about 20 inches.
The temperature rarely exceeds 80 degrees in summer, while the
winter months average about 45 degrees.
Such soils and such climatic conditions combine to force wealth
upon every industrious tiller of the soil. Clover yields from four
to six tons per acre.
Oats and vetches for ensilage purposes yield five to seven tons
per acre. Fifty to seventy-five tons of cabbage or mangles per
acre are not uncommon, and onions and potatoes produce from six
to ten tons. The fruit trees, particularly cherries, apples, and
pears, produce wonderful crops. Cattle can graze ten months in the
year or more, and the products of the dairies of Jefferson county
cannot be excelled.
Because of the light rainfall and moderate weather, this county is
admirably suited to poultry-raising. Green food can be had twelve
months in the year. Runs can always be open, and with proper care
hens can be made to pay $3.00 per year each.
