Anonymous, Souvenir Book of the Great Chelsea Fire April 12…
“ So intense was the heat that buildings made of solid granite crumbled, and were entirely destroyed. The fire could not be checked in its easterly course, and in a short time had traveled across the city and was stopped only by the Mystic River at the East Boston line. Almost the entire business section on Broadway was destroyed, the northern boundary of the fire on Broadway being the Boston & Maine R. R. tracks, and the southern boundary Chelsea Square. Between these two points on Broadway almost all the retail business of the city was done. ”
