I like old books, and found one with a firsthand account of the fire published shortly after it happened. Some of the details were horrifying. It also showed how fire companies and police departments from four states and the Feds right up to the president offered assistance and sent men and equipment at a moment's notice. The railways cleared the tracks and gave trains delivering aid top priority.
In the left distance, somebody appears to have hung out their wash on a rooftop.
