upwards and joins the ridge about at right angles, near the center of the western 

 side. The length of this roadway from its beginning to the mid-line of the ridge is 

 82 feet. Off the northern end of the ridge is a depression (C) with sloping sides, 

 having a maximum depth of 4.5 feet, a maximum breadth of 56 feet and 96 feet in 

 length. From this depression doubtless came material for the ridge. A short dis- 

 tance west of the ridge is a mound (D) very much spread out, which, apparently, 

 has been under cultivation in earlier times. Its basal dimensions are 80 feet by 68 

 feet; its height, 4.5 feet. Various excavations showed it to be of white sand with 

 a certain intermixture of loam, and local layers of shell. A few fragments of 

 human bones lav near the surface.

Several hundred yards from this mound, in a northerly direction, in pine 

 woods, on property of Mr. L. G. Newman, of Tampa, is a sand mound (E) about 3 

 feet in height. Considerable digging showed it to be domiciliary. A similar mound 

 (F) but a short distance from the other yielded no result. Depressions around 

 these mounds are shown in broken lines. 



Bullfrog creek is a tributarj- of the Alafia river. On this creek was formerly

 shell heaps of Tampa Bay and its location given on a plan. This mound has since 

 been largely demolished to furnish shells for the streets of Tampa, and its destruc- 

 tion was watched with interest by many. We are informed on all sides that no
