 in Thoreau’s Journal:

The intense brilliancy of the red-ripe maples scattered here and there in the midst of the green oaks and hickories on the hilly shore of Walden is quite charming. They are unexpectedly and incredibly brilliant, especially on the western shore and close to the water’s edge, where, alternating with yellow birches and poplars and green oaks, they remind me of a line of soldiers, redcoats and riflemen in green mixed together.
