" These words: if classes were in session, today is the day Nathaniel would have done his lecture on the pheromones of trees. It’s a way of catching the attention of the undergraduates for a minute with the counterintuitive news the trees, so silent and so still, have ways of reaching out to one another, lines of communication, systems of warning. There is something satisfying in it, that the plain reality of the universe reads to us like magic. Henry might go further.
