The statutory authority for the establishment of posts in Canada, as in other parts of North America, was section 4 of the Act of the 9th of Anne. This Act, however, failed to prescribe for North America rates of postage for letters passing greater distances than 100 miles. Hence, for the post from Quebec to Montreal no legal rate was ascertainable. The rate actually charged was 8d. for a single letter, and so in proportion for double, treble, and ounce letters, which was not an excessive charge, seeing that the legal charge for distances up to 100 miles was 6d. for a single letter. It proved sufficient, however; the whole scheme was completely successful and greatly appreciated by the colonists. To link this local post with the service from England, the Postmasters-General at New York arranged a connecting post to run monthly in connection with the arrival and departure of the English packets. They realized that the number of letters likely to be carried by such a post would be small and would not yield a revenue nearly equal to the expenses, the more so as, in any case, a comparatively high rate of postage would be payable on account of the great distance, and in recommending its establishment, they suggested moderate rates of charge.[103] The Act of 1765 provided reduced rates of postage for North America. "The vast accession of territory gained by the late Treaty of Peace," and the establishment of new posts in America, for which rates of postage could not be ascertained under the existing law,[104] made a new Act necessary, and the rates prescribed in that Act were fixed under the enlightened principle that moderate rates might yield increased revenue.[105] The rate which would apply to Canada, for the greatest distances, was fixed at 8d. for a single letter for not more than 200 miles, and 2d. for each 100 miles beyond 200 miles--double letters double rates, treble letters treble rates, ounce letter four times the single rate, in the usual way.
