 as shown by the pebbles of black sandstone. The whiter portion 

 of the sands of the stream deposit may have come from either layer 

 a or from layer d of the upland section. To layers b and c are 

 assigned the bones of the extinct vertebrates together with the 

 pebbles and cobbles of black sandstone. While this deposition of 

 formation No. 2 was in progress, the human bones are believed to

have received their first and only burial in connection with the 

 stream deposit. The human bones should thus naturally be less 

 scattered than the fragments of the mammals which had been shifted 

 from their original location into the stream channel. 



Following the deposition of formation No. 2 there was a period 

 of erosion, either in the form of the ordinary scour-and-fill process 

 of streams or as a result of ordinary subaerial denudation. A 

 change in the stream conditions following the erosion stage caused 

 a very heterogeneous alluvial flood-plain deposit (Sellards' forma- 

 tion No. 3) to be laid upon the irregular surface of formation No. 2.
