Read it through once

The first time I ever saw St. Louis, I could have bought it for six million dollars, and it was the mistake of my life that I did not do it. It was bitter now to look abroad over this domed and steepled metropolis, this solid expanse of bricks and mortar stretching away on every hand into dim, measure-defying distances, and remember that I had allowed that opportunity to go by. Why I should have allowed it to go by seems, of course, foolish and inexplicable to-day, at a first glance; yet there were reasons at the time to justify this course.
