Smoke.
Smoke frequently indicates the state of the air. A person being accustomed to take his pipe early in the morning will have occasion to observe that when the smoke hangs a long while in the air, and scents the place around where he has been smoking, a good hunting day always follows. (Forster.)
Smoke falling to the ground indicates rain.
Smoke ascending indicates clear weather.
When smoke rises from the bottom lands and goes to the mountain, expect an early winter. (Apache Indians.)
When the sun presses the smoke out of chimneys, foul weather follows.
When the smoke in clear weather rises vertically from the chimney, the weather will remain clear.
Snow.
If snow falls in flakes which increase in size, expect a thaw.
Soap.
