34. SECOND-CLASS ENGINEER.

(a) Age.

A candidate for a second-class engineer's certificate, whether ordinary or motor, must be not less than twenty-one years of age.

(b) Workshop and Sea Service.

Time served in the home trade is reckoned at two-thirds of the time similarly served in foreign-going vessels.

For an ordinary certificate at least two-thirds of the required period of service must have been performed in steamships, and for a motor certificate at least two-thirds must have been performed in motor-ships.
