.....Eight miners were killed in a gas explosion in the Ohio Lead Mines, East Baldwin, and are also buried in unmarked graves, except one, William Corlett of Battery Hill, aged 34. He was very young and the people of the valley paid for his burial and headstone, which lists his death as due to 'Blast and Explosion'.
