He was not above medium height, somewhat slight of figure and seemingly frail in physique, though this frailty was in appearance only as he was a man of tremendous, tireless energy. Although in no sense athletic, he made some sort of exercise in the open air each day almost a religious duty. At one time this took the form of bicycle rides, though he soon gave these up in favor of walking. His rule was to cover at least four miles a day, rain or shine, and there was no part of the less congested portions of New Haven and its environs over which he had not many times traveled as he walked unhurriedly alone, stooping somewhat, buried in thought, compelled by poor eyesight to keep his gaze fixed upon his path a few feet ahead of him. This methodical exercise he kept up until, in his last years, injuries received as the result of a fall confined him to his home.
