yielded very satisfactory results. In the additional fossil material 

 secured were specimens representing some important species new to 

 this locality, and the geologic observations made at this time are 

 proving to be valuable aids in the study of the general problems 

 involved. For example, one of the most important specimens obtained 

 on the jDrevious expedition was a crushed human skull and jaws 

 which had been found associated with fossil bones. But the exact 

 position in the geological strata was not definitely determined, owing 

 to the fact that much of the overburden or covering layer had been

removed before the skull was discovered. At the time it was made 

 certain that the sedimentary layers above the specimen had previously 

 not been disturbed since their deposit, but it was not quite clear 

 whether the fossil skull belonged in the upper six inches of the 

 Pleistocene fossil-bearing deposit, as it appeared, or whether it lay 

 in the dividing zone between this bed and the overlying deposit. This 

 doubt was caused mainly by the fact that the upper lo inches of the 

 lower bed was changed into a perceptibly darker hue than that 

 observed in the main mass below. Going back to this locality last 

 spring I extended the relatively small excavation which had been made 

 the previous suinmer, but concluded to follow a different plan than
