In addition to the skeletal material a large number of artifacts 

 have been obtained from stratum No. 3. A small arrowhead was 

 taken from this stratum by Mr. Weills in April, 1916. A rather 

 large arrowhead was obtained from near the base of the deposit 

 by the writer in June, 1916. Two spalls have been found near 

 the contact line of strata Nos. 2 and 3, and four others have been 

 obtained in sif tings from No. 3. From this deposit has been 

 taken about two dozen bone implements, as well as one wood 

 implement and one object, probably a section from an alligator 

 tooth, which apparently was used as an ornament. Broken pot- 

 tery is not uncommon in this stratum, about one hundred or more 

 pieces having been collected. Neither the pottery nor the bone 

 implements are restricted in their occurrence. On the contrary, 

 they are common to this horizon and are found at places where the 

 horizon reaches its maximum thickness and retains its covering of 

 marl rock, as well as at other places where the stratum is thinner 

 and has been cut into by the recent stream bed. 



FOSSILS FROM STRATUM NO. I 



Stratum No. 1, as previously noted, is a marine deposit in which 

 invertebrates are abundant and well preserved, the natural colora- 

 tion of the shells being in some degree retained. No vertebrate 

 fossils are known from this stratum at this locality, although from 

 shell marl, probably equivalent in age, at West Palm Beach the 

 writer has obtained the distal end of the humerus of a camel. 



A collection of invertebrates from this horizon was made by the 

 writer in 1915 and submitted to Dr. T. W. Vaughan, in charge 

 of Coastal Plains investigations of the United States Geological 

 Survey. The mollusks of this collection have been identified 

 under Dr. Vaughan's direction by Mr. Wendell C. Mansfield. Of 

 forty- two species definitely identified (17 gastropods and 25 pele- 

 cypods), all, according to notes kindly supplied by Mr. Mansfield, 

 are identical with the species believed to be now living. One 

 species only, an Area, is regarded by Mr. Mansfield as intermediate 

 between the recent A. ponder osa and the probably extinct A. 

 limula. It appears, therefore, that the marine molluscan fauna of
