344 ANNUAL REPORT SMITHSONIAN INSTITUTION, 193 4 



The development of the commercial truck followed, and by 1904 there 

 were over 400 registered in service in the United States. Motor buses 

 were next and are today, with trucks, an important adjunct to rail- 

 way service. That the development and growth of the automobile 

 is the outstanding achievement in transportation in modern times is 

 indicated by the fact that in the world today there are over 33,000,000 

 in use, a 10,000-fold increase in a little over 30 years. Of this im- 

 mense number of cars, America possesses three-fourths, including 

 over 100,000 buses and more than 3,000,000 trucks. 



The Conestoga wagon, the stage coach, the chaise, and the buggy 

 are now rare museum pieces. Each one in turn played an important 

 part in the development of highway travel, and each in its time was 

 believed to be irreplaceable. Their active lives stretched over a 

 period of from 75 to 100 years. Today, the automobile is considered 

 indispensable, but it is still a youngster, only 35 years old. Will it, 

 too, be discarded 60 years hence for something else ?
