nection with or as a service supplementary to a service by trol-
ley cars, the Public Service Commission may grant such per-
mits for a period not exceeding twenty-five years, except that
a permit may be granted for a longer period where application
is made for a permit to operate a motor vehicle or motor vehi-
cles in substitution for the whole or any part of an electric
trolley car franchise, easement or right-of-way originally
granted by local authority or otherwise acquired for a dura-
tion longer than twenty-five years, in which event, upon the
abandonment or surrender of the whole or any part of such
franchise, easement or right-of-way for the operation of electric
trolley cars, the Public Service Commission is authorized and
empowered to grant the permit or permits so applied for
for the same duration as the franchise, easement or right-of-way
which, or any part of which, is so abandoned or surrendered;
provided, however, that whenever a permit or permits are so
granted for a period or periods longer than one year, the
service rendered under such permit or permits may not. be
discontinued without the consent of the Public Service Com-
mission. But if said Public Service Commission deems the
granting of such permit prejudicial to the welfare and con-
venience of the public, then the said Public Service Commission
is hereby empowered and authorized to refuse the granting of
the same. The said Public Service Commission of Maryland is
further empowered and authorized to make such rules and reg-
ulations as it may deem necessary to govern the control and
operation of same, and enforce the same by such penalties or
forfeitures as it may prescribe, including the revocation of the
permit granted under the provisions of this sub-title.

Approved May 18, 1937.
