Hi Tracy,
There's not much to the section, but there is a clue or two you may be able to follow. The snippet is about a fire in Central City in 1873:
"The section destroyed was largely on Lawrence St. (The eastern end of Eureka Street after being intersected by Main, is so called.)
...
In those days the ground floor was the office of the
Hazard Powder Co. and large quantities of blasting powder were stored in its rear. The manager of the office, J. O. Raynolds, and his musical, talented wife, lived upstairs where Mrs. Raynolds' favorite possession could be found--a piano. When the lapping and jumping flames sped up Lawrence Street, inadequately controlled by a bucket brigade, Mrs. Raynolds realized that if their building caught fire, the powder would explode, causing wide-spread havoc and reducing her piano to bits. She gathered all the rags she could find, and tore up every sheet in the house to dip in water. While the fire singed her skirts and the men threw up dirt barricades, she kept the wooden doors, window sills, and frames of the building cool and damp by constantly changing the wet rags with which she had them draped. The powder magazine--and her piano, the only one in the camp in the '60s--were saved."
