GEOGRAPHY OF CENTRAL FLORIDA 249

 mal, and the passage of a compulsory attendance law in 1919 disturbed the equilibrium again, at least as regards enrollment. It would be very interesting to present comparative statistics for periods several years apart, but that would necessitate making allowance for the great changes in the value of money in recent years, and would take more time and space than can be spared at present. Another advantage of using the figures for 1915-16 instead of 1917-18 is that they can be compared closely with the population figures of the State census of 1915. The figures for 1919-20 would be equally interesting, but neither they nor the government figures for race, sex, age, etc., in 1920 have been published yet.
 The State reports unfortunately do not give separate statistics for city and country schools. And although they tell how many teachers in each county have homes in other counties or states, there is no indication of how many were born in Florida or any other state, which would be equally interesting. Information about the marital condition of the teachers is likewise lacking But very likely there are few if any other states that give a greater variety of information about schools than Florida does.
 Of the many kinds. of school statistics available only a few can be safely used for computing regional statistics, for when only one or two counties are considered some of the numbers (e.g., of male teachers) are so small that a slight change in them would make a considerable difference in some of the ratios or averages. But some statistics of the value and size of school buildings, school expenditures, enrollment and attendance, for the tvo races separately, are given in Table 25 for each region treated statistically* and for the whole area and State; and Table 26 gives some additional details about schools, teachers and pupils for central Florida, the whole State, and the whole United States at the same period.
 In preparing these tables a few errors in figures have been detected, but checked up pretty satisfactorily by comparison with other data in the same biennial report or corresponding figures

 *There are so few negro schools in Osceola and Brevard Counties that averages based on them might be misleading; which explains the four blank spaces in Table 25.
