If the two brigs covered Killick's land-battery with gunfire, then the Marines could go in with powder barrels, pitch-blende, and Chinese lights to torch the Thuella down to charred ribs.
They were standing at the base of the saddle ridge of pitch-blende, looking down the fold limb.
There is not the smallest indication of pitch-blende anywhere in the neighbourhood, and radium, as even those little versed in chemistry or geology are aware, is only to be found in that particular ore.
Ever since we found the pitch-blende pockets in the Great Tunnel, and discovered the simple process of extracting the radium from it, we have gone on by leaps and bounds.
