A Story Outline of Evolution 



generally and Inventive minds set about to perfecting a 

 motor that would supply the propelling power. This was 

 soon accomplished and the motorcycle came Into being. 

 With these greater speed was attained by the use of the 

 blind forces of Nature which do not tire and which need 

 only the directing force of trained Intellect to guide them in 

 their course. 



Civilization had advanced to a point where necessity 

 demanded a conveyance capable of traveling swiftly over 

 the public highways and which was not limited to the costly 

 locomotive and steel rails. The expense in constructing and 

 operating railroads prohibited their use as a means of pri- 

 vate conveyance and Inventive genius was now directed to 

 the development of a light and speedy conveyance that 

 could be used for private purposes on the public highways. 

 There were many steam driven carriages devised and oper- 

 ated on the public highways but because of the weight, 

 smoke, noise and vibration of these vehicles, their use did 

 not become general and as a whole they were not satisfac- 

 tory and were soon cast into the discard. However, they 

 formed a link In the chain of motor travel and many of their 

 mechanical principles w^ere passed on to the next generation 

 of motor vehicles. 



The next step in private motor conveyance was that of 

 the automobile, which has done more, perhaps, to change 

 the habits of mankind than any other conveyance yet 

 devised. The history of the development of the Internal 

 combustion engine and the detail of Its principles and 

 mechanics are so extensive that many volumes have been
