The Virginian by Owen Wister

I do not know with which of the two estimates -- Mr. Taylor's or the Virginian's -- you agreed. Did you think that Miss Mary Stark Wood of Bennington, Vermont, was forty years of age? That would have been an error. At the time she wrote the letter to Mrs. Balaam, of which letter certain portions have been quoted in these pages, she was in her twenty-first year; or, to be more precise, she had been twenty some eight months previous.

Now, it is not usual for young ladies of twenty to contemplate a journey of nearly two thousand miles to a country where Indians and wild animals live unchained, unless they are to make such journey in company with a protector, or are going to a protector's arms at the other end. Nor is school teaching on Bear Creek a usual ambition for such young ladies.
