"The Miners of Erin" is a science fiction version of my published story "The Miners of Lightning Spruce." I actually wrote "The Miners of Erin" first, but an editor suggested I re-write it as a western.

"Erin" takes place on a mining planet, instead of the American west, and there are a number of other "high-tech" changes. The sf version was published in my collection A Betrayal and Other Stories.

It's an interesting exercise: re-write a story in a different genre. You can learn a lot!
