In 1875 an Act of Parliament was passed making the prepayment of letters by postage stamp obligatory and imposing a fine of double the deficiency on all insufficiently prepaid letters. At the same time local or drop letters (accepted for 1c) were restricted to 1/2 oz. in weight. The Postmaster-General's Report for 1879 says:-- A reduction has been made, from the 1st September last, in the postage rate on closed parcels sent by post within the Dominion, from 12-1/2 cents per 8 oz. of weight to 6 cents per 4 oz. Under this change small parcels not exceeding 4 ounces in weight are admitted to pass for 6 cents instead of 12-1/2 cents as before. It will thus be seen that this change did away with the chief use of the 12-1/2c value and made it practically useless. Hence the reason it was never included among the series of small "cents" stamps. In 1889 another Post Office Act increased the limit of weight of single letters from 1/2 oz. to 1 oz., and at the same time increased the postal rate on local or drop letters from 1c to 2c, though a weight of 1 oz. was allowed under the new schedule. An official notice recording these changes was published as follows:-- NOTICE TO THE PUBLIC CHANGES IN POSTAGE RATES UNDER AUTHORITY OF POST OFFICE ACT 1889. The rate of postage upon Letters posted in Canada, addressed to places within the Dominion or in the United States, will be 3 cents per ounce instead of 3 cents per half ounce as heretofore. Upon Drop Letters posted at an Office from which letters are delivered by Letter Carrier, the postage rate will be 2 cents per ounce, instead of 1 cent per half ounce. The rate of postage upon Drop Letters, except in the Cities where free delivery by Letter Carrier has been established, will be 1 cent per ounce. The fee for the Registration of a letter or other article of mail matter, will be five cents upon all classes of correspondence passing within the Dominion. For the present and until further instructed, the registration fee may be prepaid by using the 2 cent Registration Stamps and Postage Stamps to make up the amount. Letters insufficiently prepaid will be charged double the deficiency as heretofore, provided at least a partial payment has been made. Letters posted wholly unpaid will be sent to the Dead Letter Office for return to the writer. JOHN G.
