In the early clays of the United
States, postal charges were paid by the recipient and charges varied with the

carriers received no government salary and their entire compensation on what
they were paid by the recipients of individual letters. In 1847 the United States Post Office Department adopted the idea of a postage stamp, which of course simplified the payment for postal service but caused grumbling by those who did not like to prepay. Besides, the stamp covered only delivery to the post office and did not include carrying it to a private address. In Philadelphia, for example, with a population of 150000, people still had to go to the post office to get their mail. The confusion A. A salary. B. Housing. C. Transportation. D.

Each has its own language, customs, names, and physical characteristics that make its members almost immediately recognizable to a person from another tribe. To the Westerner, tribalism is one of the most difficult of African customs to understand. It makes many people think of savagery, warfare, or old fashioned customs.
