John Martindale: I was tryin' to dig this well when they came.
Hopalong Cassidy: [grabbing a handful of soil and smelling it] You have any trouble diggin' this stuff?
John Martindale: Always! Black gumbo keeps oozin' into the hole.
Hopalong Cassidy: This is why Trimble wants your ranch and all the other land in the valley.
California Carlson: You mean that smelly stuff?
Jimmy Rogers: What's it good for?
Hopalong Cassidy: [laughs] There's a young fellah in the East can tell yuh. He's on his way to bein' the richest man in the world on account of it. His name is Rockefeller... John D!

Hopalong Cassidy: [being held under gunpoint by a vengeful Nolan] Well, why don't you get it over with?
Sam Nolan: I'm waitin' for you to beg me not to kill yuh.
Hopalong Cassidy: Don't make it would do much good now.
Sam Nolan: I'm not so sure about that. When a man's dead, nuthin' hurts no more. There must be somethin' that hurts worse than just killin'.

Hopalong Cassidy: Hold onto this land. Never sell Texas short. You know, what's under the ground might some day be more important to America than what's above it.
