Of all the stamps of this character, those issued by the St. Louis Postmaster have been most discussed in the Philatelical Press. The ten cents was first noticed in an article in the Stamp Collector's Magazine in November, 1863, and the five cents was mentioned in Kline's Manual, 3rd edition, 1865. Mr. L. W. Durbin first mentioned the second die of the 10 cents, Mr. Pemberton the second die of the 5 cents, and Mr. Scott is entitled to the credit of discovering the third die of each. It is unnecessary to repeat the numerous discussions, pro and con, concerning the authenticity of these stamps, since the present author discovered, and republished in Le Timbre Poste, in May, 1873, the following articles from contemporaneous daily papers, which leave no further room for doubt concerning the two values, 5 and 10 cents. _Missouri Republican._ July 17th. 1845. "Free stamped envelopes. For the convenience of those who may wish to prepay their packages at any hour of the night, Robert H. Morris, the postmaster of New York, as we learn from the Express, has prepared a variety of stamped envelopes. They are marked five cents, ten cents, &c., and under these words is the name R. H.

Envelopes of various sizes will also be furnished and of fine quality when desired by the purchaser. The plan has also been adopted by the postmaster at Washington and has met the approval of the Postmaster General. We think it not only a convenience to the public but that it will add to the revenue of the Department very considerably. The above arrangement would be a great convenience to many persons. Why should not the postmaster here adopt the same plan. We believe the public generally would buy them." This article, although a mere repetition of the article of the Express, and like that mentioning envelopes of New York and Washington which no one has ever seen, contains at the end a reference which was evidently the inspiration of the St. Louis postmaster to issue his stamps, for we read in the Missouri Republican of November 5th, 1845, the following:
