Talk on tree grafting, with 35 mm slides, overhead projections, and a map.
A branch is removed from one tree and grafted to a different type.
This was done about fifteen times the first night (2005), two grafts on the night of my birthday (2006), and one-and-a-half one afternoon visiting my parents' backyard (2007).
Grafts include: maple to pine, birch to mulberry, rose to oak
