1766 LAWS OF MARYLAND. [CH. 992

Any funds over and above that necessary for operating and
administrative purposes and any other funds not specifically
pledged by law which heretofore or hereafter remain in the
hands of the Commission may be used in the respective coun-
ties of the District, in the same proportion as the same were
collected from said counties, for the purchase, development,
maintenance and operation of parks therein; provided, how*
ever, that any such funds not collected in the said counties
may be used by the Commission as in its discretion is for the
best interests of the District.

DD. Within the District, the zoning powers or any of
them vested by Chapter 599 of the Laws of Maryland of 1933
in any municipality or council of any municipality within the
District shall be construed to be vested exclusively in and
may be exercised within their discretion only by the Boards
of County Commissioners of Montgomery County or Prince
George's County respectively acting as district councils.

Within the District any power vested by Chapter 599 of
the Laws of Maryland, 1933, in any planning commission or
board of appeals shall be construed to be vested exclusively
in and may be exercised only by the Commission or the re-
spective Boards of Zoning Appeals created or authorized by
this Act.

Insofar as the provisions of said Chapter 599 of the Laws
of Maryland, 1933, may be inconsistent with or contrary to
the provisions of this Act, such provisions of the Act of 1933
shall have no application within the District.

EE. No clerk of the Circuit Court of Montgomery County
or of Prince George's County, no administrative official, no
licensing body or board nor any person whatever shall issue
a license or permit for any commercial or industrial purpose
or for the conducting of any commercial or industrial enter*
prise or business whatsoever in a residential zone, that is, in
any district designated on the zone maps as residential within
the District. Provided, however, that in the case of a lawful
non-conforming use existing at the time of the enactment
of the respective zoning ordinances within that portion of
the District in Montgomery and Prince George's Counties,
comprising the Maryland-Washington Metropolitan District,
created by Chapter 448 of the Laws of Maryland of 1927, as
amended, the particular use may be continued and appropri-
ate licenses be issued, limited, however, to the particular use
already existing in each case; and provided further, that the
Liquor Control Board of Montgomery County may, within
its discretion, renew such licenses as were lawfully renewed
by it in 1938 for premises on which lawful non-conforming
uses either as restaurants, grocery stores, or roadside stands
