A word in regard to my advice to Mr. Fish. I received a letter from Mr. Fish some time since, in which he expressed some apprehensions that an attempt would be made by the natives to take possession of the Meeting-house, parsonage, &c. His letter enclosed rather a singular communication, signed by the Selectmen of Marshpee. I did not keep a copy of my answer to Mr. Fish, but recollect distinctly the substance of it. I alluded to the authority of the Legislature in the premises as I have above. That they intended to leave the parsonage as they found it, without undertaking to limit or modify the effect of former acts. That the appropriate mode for the natives to ascertain their rights to, or to obtain possession of, the parsonage, &c. was by resorting to the courts. That any forcible attempt by single individuals to obtain possession of the Meeting-house, &c. would be a trespass; that if numbers combined for that purpose, it would constitute a riot. I take it I hazarded no professional reputation by giving these opinions. For you very well know, that they would be correct, Mr. Fish being in peaceable possession of the premises, whether he were so by seisin or disseisin, by right or by wrong. I hope, my dear sir, that our experiment in regard to the affairs of our Marshpee friends may yet succeed. If not, I think we may console ourselves as one of old did: that if Rome must fall, we are innocent. I am, very respectfully yours, J. BARTON.
