This is ever so slightly belated, but Mondays are busy days, so hopefully Dr. Chips will forgive me for being late in wishing him another happy birthday. In his honor my botany class studied secondary growth this week, and just now so much of their understanding was tangential that they just lumbered around the lab. So cutting right to the heartwood of it, Dr. Chips has added another growth ring to his already considerable trunk, while continuing to slough off that used peridem, although on this occasion perhaps he pulled a cork or two. And never should anyone imply he has any problem with turgor in advancing age, and for a fellow so blessed with a tomentum, he has nonetheless proven to be apically, rather than annually, deciduous. Wonder what his reaction would be? Happy Birthday, guy!
