Working at Penn State is no picnic, part two

Here we see Dr. Dirt in times gone by (click pic to enlarge).

Is he:
(a) supervising a very young student's master's thesis project in the Soils Dept. at Penn State?
(b) demonstrating his general ineptitude as a babysitter by feeding an innocent toddler dirt?
(c) holding my daughter hostage unless I tell him the location of more of my coveted grouse coverts?

Yep, you guessed it--it's Uncle Pete bargaining for grouse coverts with my daughter Julia on her first birthday (c. 1998).
