Look at your world. Anticipation hangs round the trunks and low branches of hillside trees. Behind the laboratory, up on the steep slope, which spends its day much in shade now, fall has come. Everyone always guesses at the reason–some say shorter days; others say cooler weather; still others say moisture. Whatever the cause, it begins gradually in mid-August with a shy, suggestive fading of the green, which few seem to notice; then it waits; time must pass–elusive, insomniac time, falling away at the moment we would seize it.
Then on a traffic-addled September morning, one on which time has willfully mobilized against you, bringing tardiness, despite your efforts, and its attendant threat of reprimand, a spray of red pierces the leaf curtain at your left, followed by scattered assertions of pale yellow. A drowsing, purpling vine sways affably from an oak. And for a moment already passed, time was almost a thing to be grasped.
