through the same point. The meridian so drawn shall be either a
true meridian or the magnetic meridian of the date of the plat and
so marked on the plat. From the said meridian and right-angle
line all of the courses and distances and coordinates shown on the
plat shall be calculated. The coordinates shall be the distance of a
point from each of the two lines drawn through the corner of the
outline, as above directed, measured on lines parallel with said
meridian and said right angle north or south, east or west of said
corner, and those distances shall be marked on the plat as the points
where coordinates are required. The plat shall also show the coor-
dinates for each corner of each avenue, road or street intersection and
the tangent point of all curved lines shown on said plat. No distance
on the plat shall be marked "more or less" except on lines which begin
or terminate or bind on a marsh, stream or any other body of water.
The plat shall show the position by coordinates of not less than four
markers set in convenient places on the land in such manner that
from the position of one marker the position of one other marker
will be visible. These markers shall be made of hard durable stone
or of concrete three feet of which shall be planted into the ground.
From these markers, commonly called "traverse points," all corners
and lines can be readily calculated and marked on the ground. If
the alleged vacant land and/or land resurveyed lies in an area where
a traverse or coordinate system is already established and the traverse
points of said system can be found and used, such points so used
and the coordinate values thereof shall be marked on the plat; then
the meridian courses and distances and coordinates required herein
shall be shown on the plat in accordance with those of the already
established traverse or coordinate system, and no markers will be
required. The plat shall reflect, by broken lines, the outlines of any
alleged vacant land within the tract. The signature and seal of the
surveyor shall be affixed to the plat as well as to the certificate
itself.

(e)    Death or substitution of surveyor.—If the surveyor to whom
a warrant is directed dies or is unable or unwilling to execute such
warrant or to return a certificate as required herein, the Commis-
sioner may upon written request of the applicant setting forth in
detail the circumstances giving rise to such request, issue a duplicate
warrant to another surveyor designated in such request. If notice
of the original warrant has been given as provided in § 13-106,
no further notice need be given of the issuance of a duplicate
warrant. The issuance of a duplicate warrant shall not extend the
time for filing the certificate of the surveyor except upon applica-
tion as provided in subsection (b).

(f)    Charges of surveyor.—All costs, expenses and other charges
of the surveyor in executing any warrant or returning any certificate
thereon shall be paid by the applicant; and such charges shall not
be included in the cost of the proceeding before the Commis-
sioner.

(g)    Application of other law.—The provisions of this section
supersede the provisions of Article 91, §§ 1-18, in proceedings to
obtain patents.

13-108. Depositions.

(a) When required.—A certificate of the surveyor shall be
supported by proof of the holding and possession, if any, of the land
