It has always been the policy of the Canadian Post Office to admit letters to Registration at a low rate of charge for the additional security thus given, so as to leave no adequate motive, on the score of cost, for sending valuable letters through the mails unregistered; and, doubtless, the very large proportion of such letters offered for registration demonstrates a gratifying measure of success in attaining the desired object. We have here the reason for the extremely cheap domestic registry fee of 2 cents--a reason which might, possibly with profit, even, enter more deeply into the calculations and published rates of even larger countries than Canada. The above recommendation did not bear immediate fruit, but after a delay of three years the suggested special stamps made their appearance on November 15, 1875. The Report of that year says of them:-- Registration stamps have been issued, to be used by the public in prepaying the registration charges on letters passing within the Dominion, or to the United Kingdom or United States, each destination being distinguished by a different colour in the stamp, as well as by a variation in the amount of registration charge and corresponding value of the stamp. There is a red stamp of the value of two cents for prepayment of the registration charges on letters within the Dominion. There is a green stamp of five cents value for registered letters addressed to the United States. There is a blue stamp of eight cents value for registered letters addressed to the United Kingdom. These stamps are to apply exclusively to the registration charges, and the postage rates on registered letters are to be prepaid by the ordinary postage stamps. It is believed that the use of these distinctive stamps for the registration charges, will tend to give registered letters additional security against the risk which is sometimes felt of the registration escaping observation, when such letters are dealt with hurriedly or handled at night, whilst passing through the post.
