I am doing some research into the formation of a district (now part of =
Pittsburgh) that during the nineteenth century was home to dozens of =
slaughterhouses, butchers, etc. The district originally was located at =
the periphery of a city near Pittsburgh that was annexed in 1907.  =
During the mid-19th century the district developed linearly along a =
stream that emptied into the Allegheny River. By the third quarter of =
the nineteenth century the district had been absorbed into the city =
limits of this city. During the district's early years, local animals =
provided most of the slaughter. As rail transportation grew, animals =
were removed from stock trains bound for New York City from Chicago. =
Refrigerator cars, etc. pretty much wiped out the local industry.
 
What I am looking for are any studies of meat processing districts, =
especially in urban areas, that developed in a similar way. Or, since =
I'm having little luck finding sources, those that developed in any way! =
Citations for historic contexts, specialized studies and archaeological =
assessments would be welcomed.
 
Thanks, in advance, for the help.
