in Thoreau’s Journal:

A small red maple has grown, perchance, far away on some moist hillside, a mile from any road, unobserved. It has faithfully discharged the duties of a maple there, all winter and summer, neglected none of its economies, added to its stature in the virtue which belongs to a maple, by a steady growth all summer, and is nearer heaven than it was in the spring, never having gone gadding abroad; and now, in this month of September, when men are turned travellers, hastening to the seaside, or the mountains, or the lakes — in this month of travelling — this modest maple, having ripened its seeds, still without budging an inch, travels on its reputation, runs up its scarlet flag on that hillside, to show that it has finished its summer’s work before all other trees, and withdraws from the contest. Thus that modest worth which no scrutiny could have detected when it was most industrious, is, by the very tint of its maturity, by its very blushes, revealed at last to the careless and distant observer. It rejoices in its existence; its reflections are unalloyed. It is the day of thanksgiving with it. At last, its labors for the year being fully consummated and every leaf ripened to its full, it flashes out conspicuous to the eye of the most casual observer, with all the virtue and beauty of a maple — Acer rubrum. In its hue is no regret nor pining. Its leaves have been asking their parent from time to time in a whisper, “When shall we redden?” It has faithfully husbanded its sap, and builded without babbling nearer and nearer to heaven. Long since it committed its seeds to the winds and has the satisfaction of knowing perhaps that a thousand little well-behaved maples are already established in business somewhere. It deserves well of Mapledom. It has afforded a shelter to the wandering bird. Its autumnal tint shows how it has spent its summer; it is the hue of its virtue.
