when filed, subject to the respective rights of protest, resurvey,
review and appeal, provided by Sections 91, 92, 93, 94, 94-A,
94-B, and 103 of this Act, shall be taken in all the Courts of this
State as conclusive evidence of the boundaries and limits of all
natural oyster beds, bars and rocks lying within the waters of
the County wherein such report and survey are filed, and sub-
ject to the provisions of said Sections shall be construed to mean
in all of said Courts that there are no natural oyster beds, bars
or rocks lying within the waters of the Counties wherein such
report and survey are filed, other than those embraced in the
survey or resurvey authorized by this Act, and that all areas
of the Chesapeake Bay and its tributaries within the State of
Maryland, not shown in the survey or resurvey to be natural
oyster beds, bars or rocks, nor within the neutral zones sur-
rounding the natural beds, bars or rocks as hereinafter provided,
shall be construed in all the Courts of the State to be barren bot-
toms, and open for disposal by the State for the purpose of pri-
vate planting or propagation of oysters thereon under the pro-
visions of this Act, provided that the said survey or resurvey
and report shall not be so construed as to affect in any manner
the holdings by citizens of this State in any lot which may have
been appropriated or taken up under the laws of this State prior
to the third day of April, 1906.

SEC. 90. The said Board, in defining the natural beds and
bars, shall exercise its judgment liberally in favor of the nat-
ural beds and bars and allow a reasonable margin of the barren
bottoms, rather than encroach on a natural bed or bar. The
natural beds or bars shall be bounded by straight lines, even
though some portions of barren bottoms may thus be necessarily
included within such lines. All natural beds or bars shall be
surrounded by neutral zones 200 yards wide in the Chesapeake
Bay and Tangier Sound, and 50 yards wide elsewhere, to be
located contiguous to but entirely outside of the natural beds and
bars, which neutral zones shall be excluded from the operation
of this Act, and no person shall be permitted to plant or culti-

his own use; provided that nothing herein contained shall effect
in any manner leases actually issued and in force prior to the
approval of this Act within such neutral zones.

SEC. 93. Such amended survey shall be filed in the offices of
the Clerks of the Circuit Courts for the respective Counties in
which the original surveys hereinbefore provided are required
