SECRETARY’S REPORT 83 
Others have already been analyzed by Mrs. Catherine Clisby of 
Oberlin College, preparatory to establishing a fossil pollen sequence. 
Geologic-climatic investigations have been carried out by Alan H. 
Coogan, who was employed for the purpose by the River Basin Sur- 
veys. He worked in collaboration with William N. Irving in the 
lower Big Bend Reservior area. Other less specific researches are in 
progress to bring all possible chronology techniques to bear on this 
one basic framework for Missouri Basin chronology. 
The laboratory and office staff devoted its full time during the 
year to processing specimen materials for study, photographing speci- 
mens, preparing specimen records, and typing and filing of records 
and manuscript materials. The accomplishments of the laboratory 
and office staff are listed in the following tables:
