be done only through a reexamination, but without cost to the 

 licensee. 



No person shall be eligible to examination for license unless 

 he furnishes proof that he has been employed about a steam 

 boiler or a steam engine for a period of not less than 2 yr., 

 prior to the date of application, which proof must be certified 

 by at least one employer and two licensed engineers. It shall 

 be the duty of every licensed engineer when he vacates a posi- 

 tion as engineer to notify the boiler inspector of such fact. 

 Failure to do so is punishable by suspension of license for such 

 a period of time as the boiler inspector may determine. 



Tennessee. In Tennessee, the license laws are administered 

 by a board of inspectors appointed by the mayor or the presi- 

 dent of cities having a population of 30,000 or over. The 

 duties of the board are to examine into the qualifications of 

 applicants for license to act as engineers of steam plants, The 

 board holds sessions at least twice each month for the purpose 

 of receiving applications for license. The laws state that the 

 board shall grant certificates of license for 1 yr., to all appli- 

 cants who, on examination, shall have the skill, experience, 

 and habits of sobriety requisite to perform the duties of an 

 engineer. Any owner or user of steam boilers of a capacity 

 of not over 75 sq. ft. of heating surface and a pressure of not 

 over 25 Ib. per sq. in., and of all boilers of a pressure less than 

 15 Ib. per sq. in. used for heating purposes only, may obtain 

 a permit from the board to employ a careful and trustworthy 

 person instead of a licensed engineer, such person to be recom- 

 mended by two citizens, one of whom shall be a steam user or 

 a licensed engineer. When boilers are used for engines run day 

 and night, the owner or user of them may employ some trust- 

 worthy person in place of a licensed engineer, not exceeding 

 12 hr. at a time, under the instructions of a licensed engineer- 

 in-charge. 



In case an owner may be deprived of the services of a 

 licensed engineer, he may put a careful and trustworthy per- 

 son in charge for a time not exceeding 6 da. In places where 

 there are steam boilers or steam-generating apparatus of over 

 10 H. P., and when such apparatus is in use, there must b> 

 employed at least one licensed engineer.
