Snow falls two years out of three, but soon melts.
Snow falls rarely, and when it does, it melts at once.
In the interior the surface of the inland ice is composed of dry snow which never melts, and is constantly packed and worked smooth by the winds.
In boiling liquids its formation may be prevented by adding paraffin wax; the wax melts and forms a ring on the surface of the liquid, which boils tranquilly in the centre.
