The work of the ten inspectors consists in the collection of samples 

 of oils, which are sent to the laboratory at Raleigh for analysis by 

 the Oil Chemist, and in the cancellation of stamps, gauging of vessels 

 containing illuminating oils, and seeing that they are properly labeled. 

 It is also their duty to see that the law and regulations are carried 

 out in every way. This work, which entails a voluminous cor- 

 respondence, is handled by the Oil Clerk of the Department of 

 Agriculture. It is also the duty of the Oil Clerk to deliver the 

 stamps to the oil companies and dealers upon the demand for the 

 same and to make settlement with the State Treasurer for the quan- 

 tity delivered. He also keeps the books and records of the office.
