Famous quotes containing the words mound and/or builder:
“Worn down by the hoofs of millions of half-wild Texas cattle driven along it to the railheads in Kansas, the trail was a bare, brown, dusty strip hundreds of miles long, lined with the bleaching bones of longhorns and cow ponies. Here and there a broken-down chuck wagon or a small mound marking the grave of some cowhand buried by his partners on the lone prairie gave evidence to the hardships of the journey.”

“The structure was designed by an old sea captain who believed that the world would end in a flood. He built a home in the traditional shape of the Ark, inverted, with the roof forming the hull of the proposed vessel. The builder expected that the deluge would cause the house to topple and then reverse itself, floating away on its roof until it should land on some new Ararat.”
