Helium Once Worth $5,000 Costs under Two Cents (Dec, 1936)
It looks like Helium will remain cheap, at least for a few more years. (BTW, every single publication I saw felt the need to make a Helium pun in the headline)
Helium Once Worth $5,000 Costs under Two Cents
Twenty years ago it would have cost you $5,000 to buy enough helium gas to inflate a small balloon about two and one-half feet in diameter. Today the same amount of gas can be had for one and one-half cents. The drastic reduction in the price of helium since 1916 is due to the discovery by the U. S. Bureau of Mines of a method of recovering helium from natural gas instead of from the air.
COAL DIGGERS AND DYNAMITE OUST HOMES (Mar, 1924)
Wow, it must have really sucked for the people who still lived in the neighborhood…
I’m waiting on confirmation Charlie, but it looks like this happened in South Scranton, PA.
COAL DIGGERS AND DYNAMITE OUST HOMES
Steam shovels, locomotives, and dynamite have invaded a residential section of a Pennsylvania city to mine a rich vein of coal that was recently found under the district. Yawning gorges have been blown and dug into the earth at the sides of the streets, where the rumble of heavy machinery is punctuated with blasts of explosives. Great lengths of railroad track have been laid in a winding path through the neighborhood to carry the mined fuel away. Guard rails were built on the brinks of the deep openings to prevent accidents to unwary pedestrians. Thousands of tons of soil, rock, and anthracite coal have been torn from the land since operations began.
