89. As soon as practicable after the 1st day of April, 1906,
the said commissioners shall organize, and shall at once
proceed, with the assistance of such person or persons as
may be detailed by the United States coast and geodetic
survey, and the United States fish commissioner, to aid them
in their work, and of such persons as may be appointed under
the preceding section, to have laid out, surveyed and designated
on the said charts, the natural beds and bars, and shall cause
to be marked and defined as accurately as practicable, the
limits and boundaries of the natural beds, bars and rocks,
us established by said survey, and they shall take true and
accurate notes of said survey in writing, and make an accurate
report of said survey, setting forth such a description of land
marks as may be necessary to enable the said board, or their
successors, to find and ascertain the boundary lines of the said
natural oyster beds, bars and rocks, as shown by a delineation
on the maps and charts herein provided; said report shall be
completed and filed in the office of the board in the city of
Annapolis, within ninety days after the completion of the sur-
vey of any county. Said commissioners shall cause the same
to be published in pamphlet form, and transmit copies of the
same to the clerks of the circuit court for the respective coun-
ties, where the charts have been filed or directed to be filed as
hereinafter provided; the said report to be filed by the clerks
of the several counties in a book kept for that purpose. And
the said survey and report, when filed, subject to the right of
appeal hereafter provided for, 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 counties wherein such survey and report are
filed, and shall be construed to mean in all of the 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
tiled, other than those embraced in the survey hereby author-
ized, and that all areas of the Chesapeake bay and its tribu-
taries within the State of Maryland, not shown in the survey
to be natural oyster beds, bars or rocks, shall be construed in
all (he courts of the State to be barren bottoms, and open for
disposal by the State for the purpose of private planting or
propagation of oysters thereon, under these provisions; pro-
vided, that the said survey and report shall not be so construed
