TITLES AND ABSTRACTS OF PAPERS PRESENTED AT THE MORNING SESSION 

 AND DISCUSSIONS THEREON 



STRAND AND UNDERTOW RECORDS OF UPPER DEVONIAN TIME AS 

 INDICATIONS OF THE P RET AILING CLIMATE 



BY JOHN M. CLARKE 



{Abstract) 



The effort to interpret the strand markings of the Portage sandstones in the 

 light of records made on existing strands indicates that certain of tliese 

 ancient strand marlis are caused by the indirect action of ice, and that some 

 of them may be due to ice crystallization. It is further indicated that such 

 records of long continued cold are in accordance with other evidences of pre- 

 vailing cold conditions during a part of the Middle and Upper Devonian period. 



Read in full from notes. 



Questions were asked by Dr. E. Blackwelder and Mr. F. Leverett and 

 answered by the author.
