Mr. Hill succeeded likewise in proving many of the facts adverted to in the preceding chapter. He showed that the high rates were so excessive (not only varied according to distance, but doubled if there was an enclosure, with _fourfold_ postage if the letter exceeded an ounce in weight) as greatly to diminish, where they did not absolutely prevent, correspondence. Not only so, but the high rate created an illicit traffic, involving all classes of the country in the meshes of a systematically clandestine trade. These facts and their results on the public revenue shine out of the pamphlet as clear as noonday. But this was not all. The expenses of the department, or the _secondary distribution_, might be much reduced by simplifications in the various processes. The existing system resulted in a complicated system of accounts, involving great waste of time as well as offering inducements to fraud. The daily work of exposing letters to a strong light, in order to ascertain their contents, also offered a constant temptation to the violation of the first duty of the officers of the State, in respect to the sanctity of correspondence. If, instead of charging letters according to the number of sheets or scraps of paper, a weight should be fixed, below which, whatever the contents of a letter, a certain rate be charged, much trouble would be saved to the office, not to speak of any higher reason. Again, he suggested that if anything could be done to expedite the delivery of letters by doing away with the collection of postage from door to door, a great object would be gained; that five or six times the number of letters might be delivered with the existing machinery, and this even in less time than under the old system. The only requisite was, that some plan for the prepayment of letters should be devised, so that the Post-Office might be relieved from the duty of charging, debiting, &c. and the letter-carriers from collecting the postage. The Post-Office authorities had had the question of prepayment, by means of some kind of stamp or stamped covers, under consideration prior to this time. The Commissioners of Post-Office Inquiry deliberated on the measure in the early part of 1837 (after Mr. Charles Knight had suggested a penny stamp, or stamped cover, for collecting the now reduced postage on newspapers), considering it very favourably. Hence it arose that that part of the proposals relating to prepayment by stamped labels or covers, formed part of Mr. Hill's scheme, and was considered with it.
