A cellphone snap from a walk around the College of Agriculture at Cornell.

It covers over 800 acres, with its pastures, test plots, arboretum, etc.

so I was glad to see a map on the wall of an old barn.

It turned out to be unlabeled and not much use as a guide to the campus, but still kind of intriguing.

Not roads, I think, but maybe geologic faults?

or pathways only a cow would understand

P.S.

On ceramic or enamel surfaces, it might be described as “crazed with cracks,”

so maybe this is indeed, a sign of the times, as Dave suggested.
