242 FLORIDA GEOLOGICAL SURVEY-I3TH ANNUAL REPORT

 A "Guide to Florida" by Harrison Rhodes and Mary W. Dumont, published in 1912, devotes 27 pages to a hotel directory of the State. There is no explanation of how complete it is supposed to be, or whether the rates quoted are American or European plan, and in some cases either the rate or the capacity is left blank. But the towns and hotels omitted are mostly very small ones, and the rates in nearly every case are evidently American plan, and the list is useful for indicating the distribution of the tourist business and calculating the average cost of board in each region, if nothing else.
 According to that there were within the area under consideration accommodations for i5,68o visitors, at an average minimum rate of $2.47 per day, American plan.* About 1i% of the rooms were in the lime-sink region, mostly on the coast thereof in Pinellas County, 23.2% in the lake region, the same in the western division of the flatwoods (mostly at St. Petersburg), 35.6% on the east coast, and the rest scattering. The average rates per day were about $3.00 in the lime-sink region (one hotel on the coast contributing a large part of this), $2.21 in the lake region, $2.00 in the western division of the flatwoods, and $2.88 on the east coast. (Of course to convert these figures to present-day prices they would have to be multiplied by about two, on account of the depreciation of money during the recent var.)
 A winter resort directory of the South issued by the Atlantic Coast Line for the season of 1914-15 seems to have about the same degree of completeness as that just mentioned, and the number of hotel accommodations in central Florida listed in it is about 20,000. A similar publication for 1920-21 increases the number to about 24,000, 9.7% of which are in the lime-sink region, or on the coast thereof, 34.7% in the lake region, 21.4% in the western division of the flatwoods, and 26.5% on the east coast. (In all these calculations Tampa has been divided equally between the lime-sink region and the flatwoods.) Hotels are most numerous in the lake region, but they average smaller there than on the east coast.
 *This average is not simply the sum of the rates divided by the number ot hotels, but a weighted average obtained by multiplying each rate by the number of rooms before adding. Where the rates given are obviously European they have been multiplied by three or four.
