PROCEEDINGS OF THE THIRTY-THIRD 

 ANNUAL SESSION 



Held at Cedar Falls, April 25 and 26, 1919 



The meetings of the thirty-third session of the Academy were 

 held at the State Teachers College on April 25 and 26, 1919. The 

 opening meeting was called to order by President Beyer at 1 :30 

 Friday afternoon in the recitation room of Chemistry Hall. After 

 a short business session, Doctor Beyer delivered the Presidential 

 Address on "Some Problems of Conservation," after which the 

 Academy passed to the reading of papers of general interest. Fol- 

 lowing these the Academy separated into sections of Zoology, Bot- 

 any, Geology and Physics for further reading of papers. 



At 6:45 the Academy convened for a special war film exhibit, fol- 

 lowing which President Emeritus Macbride addressed the Academy 

 on the work of Scientists in the war. It was moved and carried that 

 brief outlines of the work of the different branches of science be 

 prepared by members to be chosen and that these be printed in the 

 Proceedings. Following this meeting the members attended a re- 

 ception tendered the Academy by President and Mrs. Seerley. 



On Saturday morning the sections resumed their work and at 

 1 1 :00 o'clock the Academy met for its final business session. 



REPORT OF THE SECRETARY. 



Members of the Academy : 



It is scarcely necessary for me to remind you that this has been 

 an abnormal year in all lines of activity, to explain several features 

 of the year's work in the Academy. I strongly suspect that the 

 decrease in the number of papers to be presented at this meeting 

 may be traced to this abnormality and to the diversion and distrac- 

 tion of men's thoughts. We have, with difficulty, been able to 

 direct our minds along the customary channels of reasoned scientific 

 procedure and the results of the year's activity may perhaps reflect 

 this situation to some extent. It is but a passing phase, however, 

 and before long we shall find ourselves settled back into more 

 normal fields of productive efifort.
