The Story of Child Shooting Her Middle-Aged Husband in Tennessee, 1942

In June 1942, 14-year-old child bride Mattie Pearl Manning (née Morgan) and her father, Frank Morgan, were both convicted of second-degree murder and sentenced to 20 years in prison. They were charged in connection with the fatal breakfast-table shooting of Mattie’s 35-year-old husband, Daymon W. Manning, in Lowland, Hamblen County, Tennessee.

14-year-old Mattie Pearl, who possessed only a second-grade education, married 35-year-old Daymon Manning on February 21, 1942. She famously told reporters she married him “because he was the first man to ever kiss me.”
Just three months into the marriage, Daymon Manning was shot and killed at Frank Morgan’s home. Mattie stated that a volatile argument erupted at the breakfast table the day before over a pair of paint-stained trousers. Daymon had also reportedly threatened her.
The investigation and subsequent trial in Morristown, Tennessee, garnered national attention due to the conflicting confessions offered by the family.
Mattie Pearl originally claimed sole responsibility for the shooting, stating she acted because her husband threatened her. Weeks later, her father Frank Morgan wrote a full confession to exonerate his young daughter. When the trial commenced in mid-June 1942, Mattie Pearl changed her story again, testifying that her father had nothing to do with it. Frank Morgan subsequently repudiated his own confession.
The jury took less than an hour to find the child widow guilty of second-degree murder, while her father was convicted of aiding and abetting the crime. Both began serving their 20-year sentences on June 17, 1942. Historical records indicate Mattie Pearl (later Mattie Pearl Morgan Greene) lived until 2007.

The History of Canaries in Coal Mines

The use of canaries in coal mines began in the late 19th century as a biological early-warning system to protect miners from toxic, odorless gases like carbon monoxide and methane. Proposed by British scientist John Scott Haldane in 1895, the practice became a legal requirement in countries like the UK, the US, and Canada through the mid-20th century. It officially ended in December 1986 when digital gas detectors replaced the birds.

Before the 1890s, miners relied on primitive methods to test air quality. They used candles or safety lamps; if the flame shrank or went out, oxygen was low. If it flared up or turned blue, flammable methane gas (“firedamp”) was present.
The fatal flaw in this system was carbon monoxide (CO), or “afterdamp.” Formed after mine fires or explosions, CO is completely invisible, odorless, and highly toxic. A candle flame burns perfectly normal in carbon monoxide, meaning miners would walk directly into a lethal pocket of gas without warning.
Enter John Scott Haldane, a brilliant Scottish physician and physiologist (later known as the “Father of Oxygen Therapy”). Following a devastating mine explosion at Tylorstown Colliery in Wales in 1896, Haldane investigated the disaster and proved that the vast majority of the casualties weren’t killed by the blast itself, but by carbon monoxide poisoning afterward.  Haldane began experimenting with different animals to find a biological sentinel that was more sensitive to air quality than humans. After testing mice, rabbits, and various birds, he discovered the ideal candidate: the canary. 
Canaries possess a unique respiratory anatomy that made them flawless biological radar. To sustain flight and survive at high altitudes, canaries require immense amounts of oxygen.
Unlike humans, a bird’s respiratory system uses an intricate system of air sacs. When a canary inhales, it takes in air; when it exhales, it pushes air from its sacs into its lungs. This means it receives a double dose of oxygen, and a double dose of any airborne poisons, with every breath cycle. Because of their tiny size and fast metabolism, a canary absorbs carbon monoxide roughly 20 times faster than a human.
In a gas-laden tunnel, a canary would show visible signs of distress—agitating, stopping its song, and ultimately falling off its perch unconscious—up to 20 minutes before a human would feel a single symptom. This gave miners a critical window of time to evacuate.
A common misconception is that canaries were treated as disposable, tragic sacrifices. In reality, miners grew deeply attached to their avian companions. They kept them at the pit tops, treated them like pets, and constantly whistled and spoke to them underground.
To protect the birds, Haldane designed a highly sophisticated piece of equipment: the canary resuscitator cage. The cage featured heavy glass walls with an open, grated front door to let the mine air circulate. The moment the canary succumbed to gas and fell from its perch, a miner would slam the airtight door shut and crack open a valve on the small oxygen cylinder mounted to the top of the cage. Within seconds, the chamber would flood with pure oxygen, reviving the canary as the miners carried it to safety. The exact same bird could go back to work the next day.

The practice was formally adopted in British legislation in 1911 and quickly spread to Canada and the United States (though some regions, like the American West, occasionally used wild mice instead due to availability). The birds stayed on the job long into the high-tech era. It wasn’t until December 1986 that the British National Coal Board officially phased out the final 200 pit canaries, replacing them with handheld digital gas detectors colloquially known as “electronic noses.”
Even after they were retired, many mining communities maintained aviaries near the colliery offices as a permanent tribute to the little yellow birds that had saved thousands of lives.
