HEAT AND COLD. 



equilibrium of the forces of heat and cold during this 

 shifting process goes far in proving that heat not only 

 aided by cold carries on these processes but dictates 

 to life of all forms its course during the change in 

 the relative equilibrium of the forces. 



During the period of spring, or the period which 

 brings about the shifting of the planet when at its 

 northern extremes so as to expose a greater portion of 

 the land to the action of heat, there becomes a period 

 of expansion in all earthly substances, through the 

 action of heat. The expansion is not only applied to 

 the vegetable life and water and mineral, but is also 

 found to be present in the domains of the animal life, 

 including that of man. In every form of matter and 

 animal and vegetable life the expanding powers of the 

 sun become manifest during this period of the year, 

 and continue throughout the summer season. Again 

 adding another link in the chain tending to prove that 

 heat tends to expansion or dispersal. 



During the period of the year when the earth be- 

 gins to shift from the south so as to move toward the 

 north, being brought about by cold, there again 

 appears in the northern portion of the earth a 

 cessation of the expansion of earthly properties. 

 This cessation does not apply to vegetable life 

 and mineral products alone, but to all animal life as 

 well. This cessation of the expanding movement con- 

 tinues on into the winter and up to the time the earth 

 takes a shift to again get a greater amount of heat on 

 the portion of the earth in question.
