"As an observer of the lone test of Gilleland’s cannon recounted, ”[The chain shot] had a kind of circular motion, plowed up an acre of ground, tore up a cornfield, and mowed down saplings. The chain broke, the two balls going in opposite directions; one of the balls killed a cow in a distant field, while the other knocked down the chimney from a log cabin.”

The chain didn't break immediately. Reading the trail of destruction, I call that a resounding success. I can't help but wonder and clench my neither sphincter at the idea of what it would have done to an Union battalion.

Conservation of angular momentum--the moon's tidal effects on Earth are transferring the Earth's angular momentum to the moon. The moon speeds up as a result, which causes its orbital distance from Earth to increase over time. The Earth's loss of angular momentum causes it to spin on its axis more slowly, increasing the length of day over time. Total energy of the system is conserved.

This cannon actually belonged to my family.

I'm a descendant of John Gilleland who built it and I even grew up on Gilleland drive in Athens, GA until I was 10 years old.

The "house" was a run down shack built in the 1920's that was adjacent to the family graveyard which has since been bulldozed... The house, not the graveyard. If you go the graveyard today (difficult to find because the new houses block the view), the large family headstone actually says "Sims" on it, because the family patriarch was a privateer for the English crown who settled in GA.

When I attended UGA and was out bar hopping with buddies I would sometimes walk up to the cannon and tell them it was mine.
