INDIAN SUMMER, a season of several weeks duration in late autumn in the United States characterized by a calm trans lucent atmosphere and mellow sunshine, in sharp contrast to climatic conditions which precede and follow it, especially in tlae northeastern States and the Mississippi valley. The haziness in the atmosphere is attributed to the smoke and dust floating in the still dry air, which absence of wind and rain makes possible. Indian summer is preceded by squaw winter, a cold spell when the thermometer first dips below the freezing point.
