OIL is the source of all wealth. From the 

 soil directly or indirectly human beings 



and all animate creatures obtain food. 

 When the Creator planned this universe, 

 He apparently provided every element neces- 

 sary to sustain life and ordained that m the 

 evolution of life and death there should be no 

 destruction of elements. Complex com- 

 pounds are formed by the union of these 

 various elements, and they perform their 

 function in accordance with fixed laws, and 

 finally turn back in the form of gases, vapors 

 and mineral salts to start anew their endless 

 work of production. 



While elements may be indestructible, 

 they sometimes stray, some become lost 

 and often many are misused. Were it not 

 for such losses, nature's store of plant food 



_. would not be diminished. It devolves upon 



man therefore, to co-operate with nature in order, first, to secure from 

 re so 1 the ful benefit of its fertility, and, second, to P-vent deplet om
