Besides filling the conspicuous post indicated by his title, Mr. Secretary Jarvis was also the first Grand Master of the Masons in Upper Canada. The archives of the first Masonic Lodges of York possess much interest. Through the permission of Mr. Alfio de Grassi who has now the custody of them, we are enabled to give the following extracts from a letter of Mr. Secretary Jarvis, bearing the early date of March 28th, 1792:--"I am in possession of my sign manual from his Majesty," Mr. Jarvis writes on the day just named, from Pimlico, to his relative Munson Jarvis, at St. John, New Brunswick, "constituting me Secretary and Registrar of the Province of Upper Canada, with power of appointing my Deputies, and in every other respect a very full warrant. I am also" he continues, "very much flattered to be enabled to inform you that the Grand Lodge of England have within these very few days appointed Prince Edward, who is now in Canada, Grand Master of Ancient Masons in Lower Canada; and William Jarvis, Secretary and Registrar of Upper Canada, Grand Master of Ancient Masons in that Province. However trivial it may appear to you who are not a Mason, yet I assure you that it is one of the most honourable appointments that they could have conferred. The Duke of Athol is the Grand Master of Ancient Masons in England. Lord Dorchester with his private Secretary, and the Secretary of the Province, called on us yesterday," Mr. Jarvis proceeds to say, "and found us in the utmost confusion, with half a dozen porters in the house packing up. However his Lordship would come in, and sat down in a small room which was reserved from the general bustle. He then took Mr. Peters home with him to dine: hence we conclude a favourable omen in regard to his consecration, which we hope is not far distant. Mrs. Jarvis," the Secretary informs his relative, "leaves England in great spirits. I am ordered my passage on board the transport with the Regiment, and to do duty without pay for the passage only. This letter," he adds, "gets to Halifax by favour of an intimate friend of Mr. Peters, Governor Wentworth, who goes out to take possession of his Government. The ship that I am allotted to is the _Henneker_, Captain Winter, a transport with the Queen's Rangers on board." The Prince Edward spoken of was afterwards Duke of Kent and father of the present Queen. Lord Dorchester was the Governor-General of the Province of Quebec before its division into Upper and Lower Canada. Mr. Peters was _in posse_ the Bishop of the new Province about to be organized. It was a part of the original scheme, as shewn by the papers of the first Governor of Upper Canada, that there should be an episcopal see in Upper Canada, as there already was at Quebec in the lower province. But this was not carried into effect until 1839, nearly half a century later.
