504 NATURE STUDY. 



LESSON V. FORMATION OR STORY OF SNOW. 



Step I. formation of frost. 



Be view briefly what children observed about formation 

 of frost, the evaporation of water, its condensation to 

 water dust, the freezing of these to form frost crystals. 



Step II. Formation of clouds. 



Review briefly what was observed about formation of 

 water dust, steam, or fog, and clouds. 



Step III. Formation of snow-flakes. 



Now cannot we take the children, in imagination, to 

 cloudland, and tell them or get them to tell how the 

 snow-flakes are made ? In the sky the snow-flakes have 

 plenty of room to form perfect crystals. The frost and ice 

 crystals are crowded together. Try to follow the journey 

 of a drop of water from the tea-kettle to the clouds, its 

 change to a snow-flake, and its trip back to us. 



" Pretty little snow-flake, 

 Shining like a star, 

 Did you come to find us 

 From some world afar ? 

 Nay, my home was nearer, 

 Dear, than you suppose ; 

 From the kitchen kettle 

 Through the air I rose. 

 I longed in chilly cloudland 

 To see you once again ; 

 And so I flew, a snow-flake, 

 To your window pane."

THE SNOW-FLAKE. 



11 It was a little snow-flake 

 With tiny winglets furled ; 

 Its warm cloud mother held it fast 

 Above the sleeping world.
