 In 1'916 the leading religious denominations among the whites were Baptist, Methodist (southern), Church of Christ, Episcopalian and Presbyterian; and among the negroes Baptist and African Methodist.
 Agriculture. Agricultural conditions here are, more like those of the typical South or cotton belt than in most other parts of central Florida. The ratio of farm land and improved land to total area is indeterminate, for the same reason as density of population, but in Levy and Citrus Counties in 1900 and 1910 there. were 2.56 improved acres per inhabitant, a lower figure than in a purely agricultural region with American standards, and indicating the employment of a considerable part of the population in mining, lumbering, fishing, etc. (This is especially noticeable in the case of the negroes, who have less than one improved acre per inhabitant). Although it is impossible to get any accurate data on the subject from existing census reports, there are probably nearly as many families supported by phosphate mining as by farming, and even more may be engaged in exploiting the forests for lumber and turpentine.
 The salient features of agriculture for the last three census periods previous to 1920 are shown in the following table.

 The leading crops in these two counties in 1909, in order of value, were "vegetables", peanuts, corn, cotton (both kinds), sugar-cane, oats, sweet potatoes, oranges, hay, peaches, grape-fruit, pears, and Irish potatoes. Peanuts had probably increased in relative importance since 1899, judging by the increase in number of hogs per farm.
