Henry Fairfield Osborn
AMERICAN MUSEUM OF NATURAL HISTORYNEW YORKOFFICE OF THE PRESIDENT25 September, 1911My dear Mr. Muir:On our return from the West I found your most welcome letter of August 29th from Para, Brazil. After I left Mrs. Osborn in Glacier Park I had an inspiring trip down the Red Deer River two hundred and fifty miles in a small boat, observing the geological formations closely and collecting fossils. This journey enables me to plan for work two years ahead for our collecting parties, and I feel sure that we have a wonderful field for Upper Cretaceous life.I have been back a week now, and am fairly started with the continuation of my Titanothere Monograph. I have broken so many promises regarding this monograph that I feel in honor bound now to finish it before I do anything else. This was my principal reason for not joining you on your wonderful trip in South America.We are delighted that you are in good health, and that you feel compensated already for your journey.05110
