The process by which each water molecule, obedient to the great laws which govern nature, draws together in countless numbers to form and build themselves into countless flower-like ice crystals, which go to form solid ice is a magical, fascinating process, well worth watching.
The types of ice crystals differ, however, upon still surfaces, to those which form upon running or disturbed water. Still, such a similarity exists in all ice crystal formation, and their habits of growth, that one may get a very clear idea of the process of their development by observing it in the simple manner above described.
Their different stages of growth is very clearly divided into five or six types of crystalline formation, and they pass from beginning to end, through the various stages of development as the nuclear, or smooth-edged crystal, the scalloped, the ray-like and the branching stages of growth; after which they lose their individuality by becoming solidified and merged into the solid ice form.
