It seems strange that more of these covers have not been found. Such well-known authorities on the stamps of British North America as Mr. Lachlan Gibb and Mr. William Patterson, of Montreal, and Mr. Donald A. King, of Halifax, had not seen any until I consulted them about this one. I think it is very interesting to hear of a stamped envelope like this being used by the Post Office just before the issue of postage stamps. So far as we have been able to find out the above constitutes all that has been published regarding this envelope. We can find no further mention of it in the columns of the _London Philatelist_ or of any other journal published since 1904 nor does Mr. Howes so much as refer to it in his recently published monograph on Canada's postal issues. Yet, on the face of it, the matter seems one worthy of extended investigation by some Canada specialist or other. Its history, as given above, is similar in many respects to the history of many of the much sought after Postmaster's provisional stamps of the United States and there is a possibility that this envelope may represent a legitimate postmaster's provisional. CHAPTER III.--_The First Issue._ In common with the other Colonies of British North America Canada was granted the privilege of administrating its own postal service in 1850, and in the same year an Act was passed providing for the change. It is hardly necessary to quote this Act in full though the following extracts are of interest:-- CAP. VII. An Act to provide for the transfer of the management of the Inland Posts to the Provincial Government, and for the Regulation of the said department. II.--And be it enacted, that the Inland Posts and Post Communications in this Province shall, so far as may be consistent with the Acts of the Parliament of the United Kingdom in force in this Province, be exclusively under Provincial management and control; the revenues arising from the duties and postage dues receivable by the officers employed in managing such Posts and Post Communications shall form part of the Provincial Revenue, unless such monies belong of right to the United Kingdom, or to some other Colony, or to some Foreign State, and the expenses of management shall be defrayed out of Provincial Funds, and that the Act passed in the Eighth year of Her Majesty's Reign, and entitled An Act to provide for the management of the Customs, and of matter relative to the collection of the Provincial Revenue, shall apply to the said Posts and Post Communications, and to the officers and persons employed in managing the same, or in collecting or accounting for the duties and dues aforesaid, except in so far as any provision of the said Act may be insusceptible of such application, or may be inconsistent with any provision of this Act.
