As I was looking through the pictures I have stored on my laptop, I realized that there was yet another aspect of the landscape between the old football field and the dorms that has long since disappeared. At some point, a long hedge was planted along the path that ran between them. This hedge fairly quickly grew into a tunnel. Here’s a picture of it that I found in the scrapbook of a math grad student who graduated in 1940:
You can see the long hedge here in this 1950 aerial picture of campus:
I confess that I know neither when it was planted nor when it was taken out. (It doesn’t seem to be there in the picture I posted yesterday, which was dated 1919.) I’m in Omaha for a meeting right now, but as soon as I get back I’ll see if I can figure it out.
