FIGURE 3.-Variations in yearly rainfall at Gainesville, 1901-50.
In the last half century, yearly rainfall has ranged from 65 percent of average in 1917 to 128 percent of average in 1941; this percentage range is much less than is common in the drier parts of the Nation. The lower graph shows a dry period from 1906 through 1918 and a wet period beginning with 1941; the intervening period was neither notably wet nor notably dry.
