This discussion arose from a notice by Mr. Poole, in the Boston Daily Advertiser of April 11, 1866, of Prof. Patterson's Address which appeared about that time in print. In this notice the writer sharply assailed the claims for the Popham Colony, as set forth by the orator, and also by Mr. Kidder in a Letter which the Publishing Committee of the Celebration had printed as an Appendix to the Address. Dr. Ballard replied in the Boston Daily Advertiser of April 21; and Mr. Kidder in the Portland Advertiser of April 26. From this point, the disputants came into close quarters on the general merits of the question. As earnest historical discussion too often leads to bitterness and estrangement, we are happy to state that such has not been the result in this instance. "P.," whose notice brought on the discussion, received an official invitation to attend the Popham Celebration in August last, which he accepted. One of our firm, who was also present, can state that the hospitality of the Maine gentlemen named in the following extract from the report of the Celebration in the Boston Daily Advertiser, of September 1, is not over-stated:-- "I see to-day, among the guests from Massachusetts, your correspondent "P.," who has written of late some hard things respecting this Popham Colony. He is receiving every personal attention from Rev. Dr. Ballard, ("Sabino,") President Woods, Hon. Chas. J. Gilman and others; and the merry peals of laughter, that burst occasionally from the group, indicate that difference of opinion on historical questions need not disturb the harmony of social intercourse. As I finish this report in Bath, I understand that Dr. Ballard and the other gentlemen named have captured their friendly detractor, and taken him home with them to Brunswick, where he will doubtless receive good treatment." The Bibliography of the Popham Colony, which is appended, was compiled, at our request, by Mr. Poole; and, so far as the newspaper articles, and the minor pieces connected with the first Celebration, are concerned, it was made chiefly from the collection preserved by Mr. John Wingate Thornton, of Boston, who has kindly placed them in our hands for that purpose. The list was then sent to Dr. Ballard, who has contributed the articles in his possession which were not already included. W. & L. [_Boston Daily Advertiser, April 11, 1866._] THE LAST POPHAM ADDRESS.
