"She was born in 1907 in the boom of the Industrial Age about 18 miles up the Allegheny River from Pittsburgh, in the town of Springdale. From her bedroom window, she could see smoke billow from the stacks of the American Glue Factory, which slaughtered horses. The factory, the junkyard of its time, was located less than a mile away, down the gently sloping riverbank from the Carsons' four-room log cabin. Passers-by could watch old horses file up a covered wooden ramp to their death."
