554 Our Surroundings 



Progress in industry has been rapid since the invention of the 

 steam engine and the turbine, and the development of electric 

 power. Modern machinery is increasingly automatic, reducing 

 hand labor and cost of production. Progress in transportation 

 has also markedly aided industry. 



Science has rendered exceptional service in the protection of 

 health and life by introducing better treatment of diseases, by im- 

 proving sanitary conditions, and by showing us how to select, pre- 

 pare, and preserve our foods. 



Science affects our daily lives in countless ways. It is responsi- 

 ble for comfortable and sanitary homes, and for their conven- 

 iences. It provides many of our amusements. It protects our 

 lives in endless ways.
