GEOGRAPHY OF CENTRAL FLORIDA 275

negroes there was greater uniformity, about one-third being above the average and two-thirds below.* In central Florida about 8% of the negro farmers had larger farms than the average white man, while the corresponding figure for the whole State was about 7%, and for Marion County only about 2%. The greatest inequality in our area is in Osceola County, where only 9% of all farms (for both races, but there are so few negroes that the results would be much the same for whites alone) are above the average in size. But the largest farms are cattle ranches, with very little improved land, and if improved land alone was considered Osceola night not show up very different from some of the other counties.
 If we only had similar graded figures for acreage of improved land, value of land and buildings per farm, yield of different crops, etc., the results would be very significant. But in the absence of such data we can safely assume that the resulting curves would all be steepest in their higher portions, as we already know to be the case with those for ages of the population, grades of school children (fig- 43), cities arranged in order of size, mountains in order of height, rivers in order of length, etc.

 CROPS
 Relative Importance
 In the regional descriptions the relative importance of the principal crops for 1909, 1913-14 and 1917-18 has been -indicated, without specifying how much'of the total crop value is contributed by each, except sometimes in the case of one or two near the head of the list. Table 36 shows for each of the more important crops what percent it made in 1909 of the total crop value in each region for which we have statistics, as nearly as can be ascertained from the 13th U. S. census. The value of each crop in each county is not given by the Tederal census as it isiby the State census, but it has been estimated by assuming that the value per bushel, pound,
 *Fcom these curves it can be determined that the median sizes of farms in the seven central Florida counties that had over ico negro farmers in 1910 were about 43 acres for whites and 30 for negroes; that is to say, there were just as many farms above as below these sizes. But the average sizes for the two races, as shown in Tables 34 and 35, were 102.5 and 43.5 respectively.
