The New postal arrangements.
--The Montgomery Advertiser, of May 17th, speaking of the Confederate postal service, says: ‘"The law which goes into operation on the first proximo, requires prepayment in money until the necessary stamps and stamped envelopes can be procured, at the rate of five cents per letter, weighing not more than half an ounce, for any distance not exceeding five hundred miles, and five cents additional for every half ounce or fraction of an office; over five hundred miles, double these rates. Advertised letters will be charged two cents in addition to the regular postage. All drop letters and letters placed in the office for delivery only will be charged two cents; newspapers, circulars, and other printed transient matter, placed in the office for delivery only will be charged one cent. The postage on weekly newspapers within the Confederate States will be ten cents per quarter; for a paper published six times per week six times that amount, and for other publications in proportion. Monthly magazines weighing not more than one and a half ounces will be charged two and one-half cents per quarter, and periodicals published quarterly or bi-monthly will be charged two cents per ounce. Transient newspapers, pamphlets, periodicals, engravings, &c. not exceeding three ounces in weight, and published within the Confederate States, two cents. For all matter coming from beyond the Confederate States double postage will be charged. Publishers of newspapers are entitled to send and receive from their respective offices of publication one copy of each publication free of postage." ’
