JANUARY. 

 PLANTS. 



Effect of frost upon plant life. 

 ANIMALS. 



Food of animals that do not migrate or hibernate. 



MINERALS. 



Study quartz crystals; form, size, color, hardness, texture, varie- 

 ties. 



ELEMENTARY GEOGRAPHY. 



Compare snow line with December; when farthest north; farthest 

 south; range of latitude covered; influence of Great Lakes. 



Compare marks on shadow stick with previous months; effect upon 

 temperature. 



NOTE. Relate effect of frost upon plants, scarcity of food of animals, the 

 southern limit of snow line, the length of shadow to movement of sun. 



Examine snow crystals. Note form, size, and law of crystallization. 



Saturate solution of salt, alum, chalk, soda, blue vitriol, copperas, bichromate 

 of potash. Note temperature of water in solution. Place solution in shallow 

 dish or bottle with a string suspended in it. Evaporate rapidly; slowly. Relate 

 solution to erosion of rocks; crystallization to crystalline rocks, quartz-crystals, 

 geodes, etc. 



FEBRUARY. 

 PLANTS. 



Any awakening in plant life. Observe trees for mosses. 



ANIMALS. 



Any appearance of animal life. 

 MINERALS. 



Distinguish different species of quartz. Relate hardness of granite 

 to quartz. Association of quartz with other minerals. 



ELEMENTARY GEOGRAPHY. 



Compare snow line and zero isotherm with January. Influence of 

 wind upon course of storm. 



Compare angle of sun's rays at New Orleans and Detroit. Com- 

 pare relative amount of heat and light; effect upon life.
