ABSTRACT
After his eighty-first birthday Davis began to travel less. His global wanderings were over and his major lecture tours virtually completed. His venture to Columbia University, New York, was specially arranged by his dear friend Douglas Johnson and was his last prolonged lecture tour away from California, although he continued to attend conferences and give single lectures in the American East. The warm winters of southern California suited him well and there seems no doubt that he had now to be more careful of his health and of catching cold.
