The sources of government revenue other than taxes, are various, and differ in different countries. In our consideration of the revenues and expenditures of our national, state, and local governments we shall have occasion to notice the various means by which their treasuries are filled. _#The Federal Government#_ raises its revenues independently of the other governing bodies, from different sources, and by a different set of officials. Besides taxation, the principal source of revenue is from the sale of public lands. Federal taxes are of two kinds: 1. Customs duties. 2. Excise or internal revenue duties. Of these, much the greater sum is raised from customs duties. For the year 1889,[1] the total net receipts were $387,050,058. Of this $223,832,741 was derived from customs, and $130,894,434 from the internal revenue duties. The sale of public lands yielded in that year $8,038,651. The miscellaneous revenues amounted to $24,297,151. [Footnote 1: For fiscal purposes the year begins July 1st.] Customs or tariff duties are taxes which have to be paid on a large class of goods imported into this country from foreign countries. These charges are collected by Government collectors, stationed in all our principal seaport cities, who inspect all incoming vessels and determine the amount to be paid, according to the rate determined by Congress. This system constitutes the so-called protective tariff policy of our country. Those commodities not so taxed are said to be on the "free list." How much, and on what articles these duties shall be levied, is the question upon which the Republican and Democratic parties differ; the former favoring high, and the latter low rates, that is to say merely enough to support the Government, or, as it is termed, "a tariff for revenue only." Internal revenue duties are those taxes collected by the government from its own citizens upon a small class of articles produced in this country. The chief items of this class are distilled liquors, tobacco, and oleomargarine. In 1889, out of the $130,894,434 received from internal revenue, there was derived from spirits and fermented liquor $98,036,041; tobacco, $31,866,861; oleomargarine and miscellaneous, $991,532. These duties are collected by Government collectors stationed in every United States district, who visit the distilleries, collect the taxes, and see that the law is enforced. In several Southern States attempts to evade the law are very frequent and difficult of detection. The expenses of the vast postal system conducted by the Federal Government are very nearly defrayed by the charges made for postage, and the amount received by fees more than equals the expense of the Patent Office.
