Elsie Eiler is the mayor of Monowi,a tiny town in northern nebraska,USA.But that ısnt her only job.She ıs alse the town clerk,the town treasurer,the librarian,and she works ın the bar.Why has she got a lot of different jobs ? Because there's nobody else to do them.Monowi has got a population of one -Elsie

Monowi is an extraordinary sight.There are about twelve old wooden houses.They are all empty and are surrounded by a few trees,some old cars and lots of rubbish.The town ıs completely silent.An old yellow school bus ,with no wheels or seats,stands next to the small school.The school closed 40 years ago.Opposite Elsie's bar is an old buildings,filled with rubbish.İt was a shop but it closed şn the 1950s.Even the church has been closed since 1960.

The busiest time for Monowi was in the 1930s.Then,the population was 150,mostly farmers and their families.There was a railway too.However the farmers couldnt compete with the enormous industrialised farms.They left the town to look for other work.In 1971,the railway closed and the town began to die:three yeasrs ago,the last inhabitant,apart from Elsie and her husband,moved away.Then Elsie's husband died,and Elsie became the town'S only inhabitant.Elsie's son and daughter left years ago to find work in bigger towns.'The small farmers and businessmen cant make any money here.'says Elsie.İt is the same in other small towns in the region.Between 1996 and 2004,almost 500.000 people left the rural states of Nebraska,Kansas,Oklahoma,North Dakota,South Dakota and Lowa,and went to live in big cities.

Now Elsie lives alone,but she isnt loneyly.Her food is good,the beer is cold,and farmers and truck drivers travel a long way to eat at her cafe.'One day Monowi will just be memories,and it will probably turn to dust.'she says.'but I like it here,and as long as I can take care of myself,I'll stay here.
