Any one who has traveled fast through a heavy, damp fog will remember how wet the front of his coat has been from the tiny drops of moisture. Such dampness falling from the clouds, freezing on its way down or just as it starts to fall, into clusters of little ice needles, is snow.

Each of these wee ice crystals glitters brightly in the light, making the snowflake look white like snow, instead of likeclear ice. A snowflake is not made in the same' way as a hailstone. Hail is made up of rain drops, which are driven about among thunder clouds and upward into freezing air by hard-blowing, cold wind, and frozen into ice, or ice a...
