later stream deposits, stratum No. 3 of the section, cuts sharply 
into the older formation, and for a short space cuts entirely through 
stratum No. 2 and into the shell marl beneath. 
Fig. 14. Detail of the section of the south bank from about 470 to 478 
feet west of the bridge. Horizontal and vertical scale, 1 inch equals about 2 
feet. Human bones are found at or near the contact line between strata 2 and 
3. The strata Nos. 2 and 3 correspond to strata 2 and 3 of the general sec¬ 
tion. No. 3 is an alluvial deposit made up of alternating layers of sand and 
muck which were undisturbed. For a photograph of this exposure see fig.

The bones from this skeleton were taken from the bank by 
Ayers, Weills and the writer. In addition to the ulna and humerus, 
there were obtained from cavings from the bank a part of a 
sphenoid bone, scapula, and a left upper incisor; and in place in the 
bank the left ulna, a femur, radius, base of a jaw, parts of the 
skull and two metatarsals. The first bone found in place was the 
left ulna, of which the proximal part only was present, although 
the distal part lacking the extremities was later obtained a few 
inches farther back in the bank. The bone next found, the left 
femur, of which only a part of the shaft is preserved, was lying 
near the ulna and at about the same level. Another piece from the 
shaft of this bone was obtained the following June, having been 
found several feet farther back in the bank. The radius, of which 
the proximal part only was obtained, was found five feet north 
of east of the ulna, and at the same place in the section, that is 
at the bottom of the bed of sand and alluvial material. Owing to
