- Bill: Here's a cablegram for you, Gene. I reckon it came from your brother in South Africa.
- Frog Milhouse: South Africa!
- Gene Autry: Yeah, it's from Tex all right, fellas. Listen to this! "Dear Gene, Barkley and I discovered a rich diamond mine in the Valley of Superstition. Stop. Need horses badly, but impossible to buy. Stop. Bring at once as many as you can round up. Stop. We can auction off those not needed at big profit. Cable your plans immediately care of John Cardigan - Dunbar, South Africa."
- Ranch hand: Diamonds, huh?
- Frog Milhouse: He's got a diamond mine. A big one, he said!
- Gene Autry: We're ridin', fellas. It's South Africa or bust!
