Several samples of central Florida soils collected by the writer 

 in 191 5 were analyzed in the same year by L. Heimburger, assistant 

 State chemist, in the same manner as those made for the 6th An- 

 nual Report, viz., the A. O. A. C. method for organic fertilizers.* 

 These samples, which are all rather exceptional, and not typical of 

 very large areas, are listed below, in regional order as before. The 

 numbers in parentheses are those under which the analyses have 

 been published in the report of the State Chemist for 191 5.
