"One hesitates, therefore, to criticize a life which, beginning with so little, has done so much. And yet the time is come when one may speak in all sincerity and utter courtesy of the mistakes and shortcomings of Mr. Washington's career, as well as of his triumphs, without being thought captious or envious, and without forgetting that it is easier to do ill than well in the world."
