exuberance of spirits
...Thoreau's Journal: 07-Oct-1857
One wonders that the tithing-men and fathers of the town are not out to see what the trees mean by their high colors and exuberance of spirits, fearing that some mischief is brewing. I do not see what the Puritans did at that season when the maples blazed out in scarlet. They certainly could not have worshipped in groves then. Perhaps that is what they built meeting-houses and surrounded them with horse-sheds for.
