grooving and notching were apparently done partly with a narrow bit of hard 
mineral, or by means of sticks, the parties using sand again as an abrasive, which 
was pushed or rubbed into the spot to be worked upon.” 
This ends the list of objects found with Burial No. 37, with the exception of 
а black material in the soil nearby, which was submitted for analysis to Dr. H. F. 
Keller who writes: “The material you sent me yesterday is a typical specimen of 
mineral pitch. It gives all the characteristic reactions of asphaltum, and contains 
2.65 per cent. of mineral matter.” 
Asphalt is found in Alabama.’ 
Vessel No. 21, a cup in fragments, since put together, has incised decoration 
showing the ribbon-fold design (Fig. 48). 
But one burial іп the mound was found at a depth of 5 feet, although a number 
were 4.5 feet and 4 feet from the surface. In addition to burials particularly de- 
scribed, eight bunches or aboriginal disturbances were met with, having no arti- 
facts in association. There were present in the mound, away from human remains, 
fragments of sheet-copper in two places and one bird-arrowpoint of quartz. 
With a full-length burial the number of which is not given in our field notes, 
were two shells ( Zu/otoma magnifica). We are indebted to Dr. Н. A. Pilsbry and 
to Mr. E. G. Vanatta, of the Academy of Natural Sciences, for all determinations 
of shells given in this report and in the three other reports in this volume.
