Indian Summer (The).
The autumnal summer; generally the finest and mildest part of the whole year, especially in North America.
The gilding of the Indian summer mellowed the pastures far and wide. The russet woods stood ripe to be stript, but were yet full of leaf. The purple of heath-bloom, faded but not withered, tinged the hills Fieldhead gardens bore the seal of gentle decay; its time of flowers and even of fruit was over.C. Brontë: Shirley, chap. xxvii.
