BICE CULTURE IN CALIFORNIA 
The average precipitation for the 12-year period from 1913 to 1924 
was 20.85 inches. In 1913, 1914, 1915, 1916, 1920, and 1922 the pre- 
cipitation was considerably above the average, while in 1917, 1918, 
1919, 1921, 1923, and 
1924 it was below the 
average. The months 
of greatest precipita- 
tion are December, 
January, and Feb- 
ruary. 
Heavy continuous 
rain in October and 
November may result 
in serious losses to rice 
growers. In the fall 
of 1920 losses were 
heavy from November 
rains, which delayed 
threshing until spring, 
and in 1922 and 1924 
rains during October 
and November inter- 
fered with harvesting 
operations and materi- 
ally increased the cost 
of production. 
WIND 
In general this sec- 
tionhas but little wind, 
though strong winds 
sometimes blow from 
the north or the south. 
The strong north winds 
are known as " north- 
ers" and are especially _ 
welcome during the rice harvest because of their effective drying 
qualities. 
Table 4 presents data showing the maximum, minimum, and aver- 
age monthly wind velocity in miles per hour from April 1 to October 
31 during the 12-year period from 1913 to 1924, inclusive.
