Whn w snd a lttr or a postcard, w hav to put stamps on th nvlop or on th card. Whn did popl first bgin to us stamps? Who was th first to think of this ida? Hr is som information about it. In th arly nintnth cntury, popl did mot us stamps. Thy had to pay for th lttrs or postcards thy rcivd. Popl didn t lik it. First, it was not convnint. Scond, somtims thy had to pay for th lttrs thy didnt want to rciv at all, such as advrtismnts. Third, th postag was high at that tim. And it was difficult for postmn to collct th postag. Thn on prson thought out an ida to solv this problm. H was Rolland Hill, a schoolmastr in ngland. H was th first to put forward a proposal to us stamps in 1850s. H thought it would b much mor convnint for popl. Thy could go to a narby post offic to buy stamps and put thm on th nvlops bfor thy snt lttrs. Th post offic could simply put sals on th stamps to prvnt thm from bing usd again. That was a good ida and it was accptd by til govrnmnt finally.
