In the middle-third part of the nineteenth century, the date of Sudbury Fight was a topic of serious controversy by genealogists and historians. I was responsible for the date that appears upon the monument that was erected in the year 1852. The conclusion that I had reached was condemned by the _Genealogical Register_ and by a committee of the Society. In the year 1866 I reviewed the evidence, on which my opponents relied, and I marshaled the evidence in support of the accuracy of the date that appeared upon the monument. In the year 1876 the town of Sudbury observed the bi-centennial on the 18th day of April, thus giving sanction to the date on the monument. At the dedication of the Sudbury monument I made the following address: ADDRESS Families, races and nations of men appear, act their respective parts, and then pass away. Political organizations are dissolved by influence of time. At some periods and in some portions of the world, barbarous races appropriate to their use the former domain of civilization, while at other points of time and space nations are rapidly advancing in wealth and refinement. If savage communities have been exterminated by superior races of men, so have the arts and civilities of the most enlightened people been displaced by the rude passions and rugged manners of barbarism. As in the natural world there is a slow revolution of thousands of years, by which every part of this globe is brought within the tropics and beneath the poles, so there appears to be a great cycle of humanity, whose law is that every portion of the race shall pass through each condition of social, intellectual and moral existence. But whatever may be the fate of families, races and nations, their influence is in some sense perpetual. The Past is not dead. By a mysterious cord it is connected with the Present. Could we analyze our life, we should perhaps find that but few of the emotions we experience are to be traced to events and circumstance which have occurred in our own time. We admire the heroes of Grecian history and even of Grecian fable. We are inspired by ancient poetry and eloquence, as well as by the bards and orators of modern times. Painting and sculpture are the equal admiration of every refined age. The virtue of patriotism has been illustrated by savage as well as civilized life. Thus every recorded event of the past has somewhat of value for us. Hence men seek to connect themselves by blood and language with Europe, or even with Asia, and delight to trace their family and name into the dark centuries of the Past. We search for the truth amid the myths and fables of Grecian and Roman history, and have faith that the ruins of Ninevah, Memphis and Palmyra shall yet declare the civilities, learning, and religion of ancient days.
