Pittsburgh, From The Northwest
This view was taken from the hill behind Sligo.  In the foreground is seen
a glass-house and dwellings of manufacturers.  On the right is the Monongahela
Bridge, the Steamboat landing, and the Monongahela House, near the end of the bridge.
To the left of that is the cupola of the University, and farther to the left, 
on high ground, the new Court House, and Cathedral, with the spire of the 
Presbyterian Church between them.  On the left is the Allegheny river, with 
several bridges leading to Allegheny town: the second bridge sustains the 
aqueduct of the canal.  Beyond these bridges are seen Bayard's town and Lawrenceville.
