Ben: Hey wait a minute. If we hook that pump shaft to a, to a windmill - that'll pump around the clock.
Adam: Why not, Pa. Windmills have been used all over the, all over the world for hundreds of years. They could turn every grindstone and every mill in Holland for centuries.
Hoss: Well, how come we ain't never used them?
Ben: Well we've never had any use for them here until now. But, you know with God's help, we could bring water to this dried up country and maybe that will be a way of stopping people from killing each other.
Adam: It's no use, Hoss. You can't talk to a man who has nothing to lose.
Hoss: They can lose their lives.
Adam: Somehow I have the feeling that it doesn't really matter to them right now.
James Doohan (Bill Collins) and Majel Barrett (Mrs. Ganther) would later appear in many episodes of the original Star Trek series and several of the Star Trek movies.
