Radio Prospecting Aids Ore Surveys For Deep Deposits
A method of radio prospecting described in Radio News uses surface wave deflection to locate ore veins and fault lines. Transmitters energize loop antennas while receivers detect deviations, enabling estimate of ore location and potential richness to reduce barren drilling. This technology is framed as vital to public welfare alongside transportation advances.

New CO Detector Trials In Mines Improve Safety
The article explains early carbon monoxide detection methods in coal mines. Canaries and mice proved sensitive but impractical, while a U S Bureau of Mines device uses glass tubes with a chemical mixture that changes color in the presence of carbon monoxide. Tubes are used by breaking end tips, with seven to eight uses before efficiency declines.
