In the National Aegis, published at Worcester, Mass., September 2nd, 1846, may be found the following item: "POST OFFICE STAMPS. The postmaster has issued postage stamps of the denomination of five cents and ten cents. They are very convenient, and will save the trouble of making change at the post office, and will enable people to send prepaid letters at times when the office is closed. To cover the expense of engraving and printing, these stamps are sold at five per cent advance upon the regular rates of postage." Maturin L. Fisher was postmaster at Worcester, from 1839 to 1849, and Andrew A. Williams was his chief clerk in 1846. The above item was recently found by the present author in searching old files of newspapers, for information about the various postmaster's stamps. No other Worcester paper seems to have noticed the matter, and no further information has so far rewarded the limited inquiry and search possible since the discovery. Both of the gentlemen in the office at the time are now deceased. XV. STAMPS OF THE PITTSFIELD POSTMASTER. A short notice published in one of the Springfield, Mass., papers, in the summer of 1874, asserts that in overhauling the vaults of the Berkshire Mutual Fire Insurance Company, of Pittsfield, a number of stamps were found that were issued by the Pittsfield postmaster, in 1846-7. Phineas Allen was postmaster of Pittsfield at the time. No further information concerning these stamps, has rewarded inquiry. XVI. OBSERVATIONS. It is by no means improbable that other similar devices were in use in other towns and cities at this period, by which prepayment of postage was secured. The salaries of many of the smaller offices depended on the amount of postage collected, and the importance of all offices was estimated by the revenue collected. It was natural, therefore, as the public demand for such accommodation grew, that the postmaster should adopt a device tending to their own benefit. There are in the possession of the present author a number of hand stamps, apparently cut from letters and envelopes, inscribed such and such a "Post Office," "5 Cents Paid," which would seem to be stamps of this kind, but in the absence of further information, are not here chronicled. The wide spread use of such stamps would appear from the following caution, published in the Courier, of New York, July 18th, 1845.
