Sci., etc. I would recommend that in all such cases the current numbers 

 be turned over to the state librarian at the end of each year. By this 

 means duplication will be avoided, the library will be relieved from the 

 expense of purchasing the books, and the academy will be saved from the 

 expenses incident to binding- and preserving them. I would further recom- 

 mend, that in cases where the books received by the academy duplicate 

 those received by the state library, the librarian of the academy be allowed 

 to dispose of them upon the best terms available. I would further recom- 

 mend, that, at the end of each year, all unbound books and pamphlets 

 belonging to the academy be transferred to the state librarian, provided 

 that the latter agrees to have them properly bound and preserved, and that 

 they continue to be available for the uses of the members of the academy. 



I would further recommend, that the academy petition the board of 

 library trustees to allow the members and fellows to withdraw, under such 

 regulations as they may devise, books from the scientific department of the 

 library. 



A memorandum of sales of proceedings and expenses incurred by the 

 librarian will be found in the treasurer's report. 

 Respectfully, 



H. Foster Bain. 



In addition to the regular papers read in full or by title and 

 published herewith, the academy was shown a very full series 

 of photographs of geological formations by Prof. J. L. Tilton. 



Prof. F. W. Sardeson, of Minnesota State university, and 

 Prof. J. E. Todd, state geologist of South Dakota, were in 

 attendance and participated in the discussions. 



Professor Sardeson was by motion invited to address the acad- 

 emy, and responded by cordially expressing his pleasure at being 

 able to attend the session, and appreciation of the courtesies 

 extended. 



Touching upon the discussion that had followed the reading 

 of papers on Loess formation he made the following: 



REMARKS ON THE LOESS. 



F. W. SARDESON, STATE UNIVERSITY, MINNESOTA. 



(Abstract.) 



The speaker commented on the common discrepancies in the 

 use of the name "loess," which are due to the different theories 

 held by scientists as to the origin of the geologic formations 

 called loess. He denied having any immediate intention of 

 trying to solve the question of origin of the deposits called 

 loess in Iowa and neighboring states, but commended the prob- 

 lem to the Iowa geological survey as the strongest agent for
