That's Randolph Street looking East from La Salle, in Chicago, circa 1900. What a wonderful snapshot of life at the turn of the previous century. There's tons to see in the pic of the hustle and bustle of life in a major US city during its hell-bent-for-leather growing years. Here's an enlarged crop of one small area...
Lots of folks walking, is the first thing I notice. Every head covered with some sort of hat as was the norm for the day. No automobiles in sight yet, but there is a cable car making its way up the street. Cable cars differ from "street cars" in that they ride on rails and are pulled along by a cable that moves in the center trench between the rails. The driver in the pull car operates a lever which grabs onto the cable when he wants the car to move and releases it when they want to stop. This one is pulling three additional passenger cars behind it so there were probably lots of stops and starts along the route.
The scoop device on the front is a pedestrian scooper designed to keep people from being run over by the cable car if they should miscalculate and find themselves unable to get out of the way.
Also of note is the detailing on the buildings along the street. Especially the stone dog statue on the 2nd floor of the Democratic Party Building and the stained glass edifice of the building next door. I'm sure the inside of the Power's Theater was something to see.
And here's the same basic view today, via Google Street View:
All the old buildings are gone. Gone are the cable cars and horses. Gone are most of the pedestrians. And gone is most of the visual interest of the area.
