perhaps fifty important uranium claims on Mars and Ramsey has consolidated all of the holdings into a single major enterprise. To say that he's cornered the market in uranium would be understating the case. He has taken possession by right of seizure, and the colonists can't get to him. They're living a hand-to-mouth existence while he lives in a heavily guarded stronghold behind three miles of electrified defenses." The kid nodded again.
