My dear Dr. Schmitt: 
The Committee on the Sixth Pacific Science Congress has de- 
cided to arrange for a number of General Sessions for presentation of 
addresses dealing with scientific problems of outstanding significance 
to the Pacific Area. These addresses will be scheduled for evening 
sessions during the Congress, and they will be open not only to mem- 
bers of the Congress but also to the general public. We hope that 
they will deal, therefore, in summary fashion with matters of interest 
to all informed people. 
In behalf of the Committee, I have besi axthorized to ex- 
tend an invitation to you to deliver one of these addresses, and I 
sincerely hope that your interest in the Congress will persuade you to 
accept. If you are able to attend the Congress and to accept this 
commission will you kindly inform me, at your earliest convenience, as 
to the exact title of your address; aid also as to any facilities, such 
as lantern projection, which would be needed in connection with it. We 
leave the subject entirely to your judgment. 
Very truly yours, 
Roy E. Clausen, 
Secretary.
