229. The said board of commissioners are empowered to make such
rules and regulations for the enforcement of the provisions of this sub-
title and for the performance of their duties hereunder, from time to
time, as in their judgment they may deem necessary and requisite; and
they may provide for the examination of applicants for journeyman
plumbers' certificates or permits, and for the issuing of certificates or
permits to journeyman plumbers after passing such examination as
said commissioners may deem proper, said commissioners designating
them cither "certificates" or "permits," as they may deem proper, and
they may provide for the issuing of permits to apprentices, so that,
however, said journeyman plumbers and said apprentices shall be
authorized to work only under the direction and control of a duly
certified master plumber; and that said certificate or permits shall be
so framed as to show that said journeyman plumbers and said appreii
tices are authorized to work only as above provided. Said board may
demand and receive from each journeyman plumber the sum of two-
dollars at the time of issuing of the first certificate to said journey-
man plumber, and the sum of one dollar for the renewal thereof each
and every year thereafter, on or before the first day of May; and said
board, at any time, may require, on any application for renewal, any
applicant to pass another examination before issuing any renewal, or
may issue any renewal without requiring any other examination, as
said board in each case, from year to year, may deem proper; but no
charge shall be made for the issuing of permits or renewals of permits
to apprentices. Said commissioners may fix the requirements of the
competency and qualification of applicants, whether of master plumbers
or of journeyman plumbers, as different standards, in their judgment,
for. different parts of the State, and may accordingly limit the certifi-
cates so as to permit the holder thereof to do plumbing work only in
certain specified sections of the State, as said commissioners may deter-
mine. Whenever by any of the general or local laws of this State it
is or shall be provided that a permit shall be granted to anyone qualified
