Chancellor Mark S. Wrighton (right) plants a tree, a Swamp White Oak, in front of Brookings Hall with students April 22 to celebrate Arbor Day/Earth Day. The new tree replaces a Swamp Chestnut Oak, which had been removed because of disease concerns. The students are (from left) freshman Dan Robinson, junior Christine Orchard, sophomore Cindy Gallin, junior Joey Stromberg, junior Will Fischer and junior Melissa Legge.
