FIFTH ANNUAL REPORT. 13 
demand for specific information regarding local soils such as can 
be supplied only by detailed soil maps of the several counties. A 
limited amount of soil mapping has already been done by the 
United States Bureau of Soils. As in the case of topographic 
maps many of the States are cooperating with the National 
Bureaus in the preparation of soil maps, and it is probable that 
an appropriation made for this purpose would be doubled by the 
United States Bureau of Soils. I would urgently recommend 
an appropriation of $5,000 per annum for the preparation of topo¬ 
graphic and soil maps. Such an appropriation may be made 
contingent upon cooperation with the national bureaus and would 
thus result in the expenditure of $10,000 per annum in the State 
for this purpose. 
EXPOSITIONS. 
National Conservation Exposition at Knoxville. —A National 
Conservation Exposition will be held at Knoxville, Tennessee, 
during September, and October of the present year. This exposi¬ 
tion is intended especially to exhibit the natural resources of the 
Southern States and to encourage their development. The 
opportunity is favorable for making more widely known both the 
mineral and agricultural resources of Florida and it is to be 
hoped that provision will be made by which the State may make 
a good showing at this exposition. 
Panama Exposition at San Francisco. —A world exposition 
will be held at San Francisco in 1915 to commemorate the open¬ 
ing of the Panama Canal. Florida by reason of its extensive 
coast line and its nearness to the canal zone is specially interested 
in this exposition, and can not afford to lose the opportunity of 
making its favorable location with regard to the canal more 
widely known. It is none too soon to begin the compilation of 
data on the harbors of Florida, and the preparation of maps, 
charts and drawings showing their relation to the canal and to 
the population and business centers of the United States, as well 
as to the lines of transportation within the United States. The 
exhibitions of the mineral and agricultural resources made for
