SNOW 



gECEMBER brings out 

 all of Nature's re- 

 sources. The old 

 mother has fed her 

 children with water in 

 the summer of their 

 growth, and now, 

 when they lie down 

 for their long winter sleep, she turns the 

 water into a blanket which she carefully 

 tucks about them. And wonderful water it 

 is of which this covering is made. Clean, 

 soft, white, porous, it is an ideal protection. 

 When she turns her liquids into solids Na- 

 ture makes crystals of them. She has only 

 a few general plans for her crystals, but her 

 variations of these plans are infinite. The 

 one she uses when she builds up the snow 

 crystals is, of all others, the one that makes 

 them pack most loosely.
