Nice map. I did some work in the Ashdown Hardware building (110 8th Ave) a couple years ago; too bad I can't read all the fine print. Looks like that building had a lot going on in 1913 (it was built in 1895, as far as I know).
"Underwriter's Fire Extgrs Thr'out, Oils kept in steel tanks in Bast., Gasoline in iron tanks in Yard, No Varnish kept in Bulk."
The former oil tank storage area in the basement is now the Bear & Kilt pub.
Can't make out the note at the top but it looks like it had a fire alarm even then. Not sure what the dots in the centre represent but I can make out 'Hose'. Anyway, it's all sprinklered now, has been for a long time.
