Last week he gave a progress report on this monster in operation. With a power input of only 50 kilowatts (more than enough to run a good-sized radio station), he and his crew have obtained beams of 16-million-volt heavy hydrogen particles and 32-million-volt helium particles. With the 32-million-volt beam, new radioactive substances throwing off electrified helium gas have been discovered...
...Father Summers' Woolworth Building laboratory a newshawk grasped an electrode in each hand as if he were experimenting with a toy shock machine. The electrodes were attached to an apparatus resembling a radio set, inside which were two balanced electrical circuits, with a two stage amplifier on the input side hooked up to a recording milliammeter. Any electrical agitation the newshawk betrayed under emotional stress would jiggle the milliammeter, make a needle correspondingly scratch a chart...

A motor compressor forced air into the vault through a ventilator until a pressure-gauge climbed to 4 Ib. per square inch over atmospheric pressure. At that level the gauge stood still nearly an hour after the air input had stopped. A valve was then opened and the compressed air wheezed...
