A magazine is nowhere defined in the Postal Laws and Regulations. A law that would increase the postage rate on “magazines,” without an explicit definition of the word, would apply to just such publications as the Postmaster-General might select in the administration of the law, and none others. No such power of discrimination should be vested in any official. The Postmaster-General is an executive, not a judicial officer, nor a lawmaker. It has been wisely and aptly said that this is a government of laws and not of men; that there is no arbitrary power located in any individual or body of individuals; but that all in authority are guided and limited by those provisions which the people have, through the organic law, declared shall be the measure and scope of all control exercised over them. There seems to be no good reason why a newspaper, which is carried in the mails once a day or once a week, should pay a less rate than a monthly or quarterly. If the Government really loses money in handling and transporting second-class matter, the loss would be greater on the former than on the latter, because a daily goes through the mails 365 times a year, a weekly 52 times, while a monthly only goes 12 times, and a quarterly 4 times. We learn from official records that daily newspapers comprise 40.50 per cent. of all second-class matter, weeklies 15.23 per cent., papers devoted to science 1.30, to education .64, religious 5.91, trade 4.94, agriculture 5, magazines 20.23, and miscellaneous 6.25. Note that it is stated that 20.23 of the whole consists of magazines; but what is a magazine? We are nowhere told, and the percentage quoted has the appearance of being founded upon conjecture.… This Commission may not be aware of the fact that the Pennsylvania Railroad will take, and does take, packages of papers for all of the great newspapers that are published along its lines, and transports them in the baggage cars for one-quarter of a cent per pound, to any station on the line, whether it is ten miles from the place of origin, or 1,000 miles from the place of origin. And yet the Department is paying the railroads approximately two cents a pound for hauling the newspapers of the country.
