duly 12, 1957 Dear George: Thank you for your wonderful posteard. It sage ‘Airmail! but I don't see how they got it on the plane, unless they fastened it under the wings. The abbreviated plan for the symposium is certainly all right with me; in mhy waye it makes life easier. The particular item 1,2,3,6 would indeed be ay own first choices, and it should work out quite well. So by all means go ahead with your invitations. We have made some slight changes in our itinerary, which is enclosed, as revised, We had a wonderful time with you, and look forwamd to seeing you again next Yours,
