The building in the upper left hand corner (you can just make out the roof and the north wall) was a mousery.
A lady I once worked with worked there when she was a teenager. She told me they raised mice for drug testing for the serum plant that was in Woodworth. She said she didn"t like it because it smelled so bad inside.
I also went to grade school with a girl who lived there. She too said the house was once a mousery.
The building still stands today (2018) as a home. The house in front of it to the north was torn down several years ago.

thanks MIKE. I know that there is information about the MOUSERY in the Valentine Snippets. https://digitalarchive.mykcls.info/
