law of gravitation and that It completes Its revolution 

 around the sun once each year and continues on repeating 

 this process; that It has once been a gaseous mass and as It 

 cooled, Its atoms formed the elements and the compounds 

 of which It Is composed; that It is made up of 88 known ele- 

 ments whose combinations make up everything of which the 

 earth and Its Inhabitants are composed; that the smallest 

 particles of Nature are the electrons carrying a negative 

 charge of electricity, and the protons, which carry a positive 

 charge of electricity; that these electrons travel in their 

 orbits around their nuclei at the rate of hundreds of miles 

 each second in the same manner that the earth revolves 

 around the sun; that the electrons make the atoms which 

 are so small that they can not be seen even with the aid of 

 the most powerful microscope; that the atoms make up the 

 molecules which are still too small to be seen; that the mole- 

 cules make up the cells of which all organic matter Is com- 

 posed; that these elements may exist in the form of a gas, a 

 liquid or a solid. 



Nothing in Nature Is constant. These tiny particles of 

 which all things are made possess the properties of force and 

 energy, the force being the cause of a change In a body and 

 energy Is the power that creates the force. Energy Is found 

 In many forms all of which may be divided Into the two gen- 

 eral forms kinetic and potential, while the natural forces 

 that accompany these such as gravitation, cohesion, chemi- 

 cal, electrical, magnetic, etc., are the forces which supply 

 motion and life to the universe. Our earth Intercepts less 

 than one two-bllllonths parts of the amount of energy that
