     Willa Cather once said,"When people ask me whether writing has been a hard or easy road,

I always answer with the famous saying: The end is nothing;the road is all.That is what I mean

when I say writing has been a pleasure.I have never used the computer with the thought that

one more task had to be done."

Like most writers,Willa Cather did not write books for the money that they brought her,but

rather for the pleasure that came in their writing.Her works were,like her,simple and full of

the vigor of her days in Nebraska,where she grew from child to young womanhood and

where she developed a deep love for the treeless land of the great plain with its wild flowers,

wheat fields and rivers.

     "It's a rather strange thing about the flat country," she wrote later."It takes hold of you

or it leaves you perfectly cold.A great many people find it very dull;they like a church

tower,an old factory,a waterfall,the country all made to look like a German Christmas card

...But when I come to the open plain,something happens.I'm home.I breathe differently."
