We find another contribution to the literature of Popham, in the elegantly printed Address of the Hon. James W. Patterson, delivered at the Peninsula of Sabino, on the 258th Popham Anniversary; which, as all the world knows without our giving the information, was August 29, 1865. Thick, creamy paper, John Wilson and Sons' best typography, and Mr. Wiggin's imprint, were among the least of the motives that induced us to seize upon and devour the contents of this delectable pamphlet. We confess to a partiality for Popham literature. Its theory is so original, so free from conventional trammels, so utterly at variance with the accepted facts of history, that it is often difficult to persuade one's self that its advocates intend anything more than historical waggery. So we read on, as in other fiction, to be amused. A false theory zealously defended commonly finds more sympathy than the truth feebly supported. The Pophamites have nailed their flag to the mast, and ask for no favors from any quarter. We admire their pluck, and, for their sakes, regret that they have so few historical verities in their ammunition locker. We have read their "Memorial Volume," from title-page to errata, as well as Mr. Poor's facetious Addenda in "Vindication of Sir Ferdinando Gorges;" not shying either at his Appendix of fifty-two solid nonpareil pages. Every other Address on the subject, and every scrap of newspaper controversy accessible, we have diligently perused; and yet the impression remains on the mind that the facts to sustain this extraordinary theory have not yet been developed. For some reason, (perhaps to surprise us the more when it does come,) the stern logic of truth is withheld; and we are served to empty assertion and vapid declamation in its stead. Every new publication, therefore, of Popham origin, or from the Maine Historical Society, is of interest, as possibly it may contain the suppressed developments. Plymouth and Massachusetts Bay are waiting, gracefully to yield the honors awarded them in history for more than two hundred years to "the Church Colony" of Sagadahoc. Is the pamphlet before us the coming document? Let us see.
