After such approval and upon receipt of such plat by the
Clerk of the Circuit Court, every such plat shall be firmly
fixed in a well bound book to be kept by the Clerk of the Court
for the purpose of recording plats and for the recording of
which the Clerk shall receive such fee as he shall determine
to be fair and reasonable.

Every plat of any subdivision shall be prepared upon paper
or cloth of such size and character, with such notations, in-
formation and markings as the Commission may, by regula-
tion, prescribe, and every approved subdivision of land shall
have such permanent markers, bound stones or stations as the
said Commission shall prescribe, which shall be shown and
designated on the plat thereof. The said Commission, the
District Council, and the County Surveyor respectively, of
the county wherein the land lies shall be furnished with copies
of said plat as approved.

SEC. 9. And be it further enacted, That in exercising the
powers granted to it by Section 8 of this Act, the Commission

of population congestion; and for the avoidance of such scat-

lack of water supply, drainage, transportation or other public

subdivided lots to the character of lots within the existing
subdivision with respect to area, frontage and alignment to
existing lots and streets; or for other benefits to the health,
comfort, safety, or welfare of the present and future popula-

other utility mains, piping, connections and other facilities
shall be installed and trees shall be planted or conserved as
