 engineer. 



No person shall receive a license who is not able to determine

 stand any given pressure of steam in the boiler. Applicants 

 must also be able to figure and determine the strain brought on 

 the braces of a boiler with a given pressure of steam, the position 

 and distance apart being known. They must be able to figure 

 and determine the safe working pressure of a boiler, such 

 knowledge to be determined by an examination in writing. 

 No license, except third grade, shall be granted to any engineer 

 who does not possess the foregoing qualifications. No license 

 shall be granted to any engineer who cannot read and write 

 and does not understand the plain rules of arithmetic. The 

 examination questions asked an applicant for license shall be 

 practical ones pertaining to boiler and engine care and 

 management; correct answers to 80% of such questions shall 

 qualify the applicant to receive his license.
