Note 663 — VIII CONCLUSION
Reading edition
"The Post Office is properly a mercantile project. The Government advances the expense of establishing the different offices and buying or hiring the necessary horses or carriages, and is repaid with a large profit by the duties upon what is carried. It is perhaps the only mercantile project which has been successfully managed by, I believe, every sort of Government. The capital to be advanced is not very considerable. There is no mystery in the business. The returns are not only certain but immediate."—Wealth of Nations, ed. 1904, vol. ii., p. 303.
