Section 1. Be it enacted by the General Assembly of Maryland,
That Section 60 of Article 17 of the Annotated Code of Maryland
(1966 Replacement Volume), title "Clerks of Courts," subtitle "Clerks
of Circuit Courts and Superior Court of Baltimore City," be and it is
hereby repealed and re-enacted, with amendments, to read as follows:

60.

Such plats must be drawn accurately to scale and may be made on
a good quality of tracing linen or be blue prints or blue or black line
prints on linen; shall contain the courses and distances of all the
outline or perimeter of as much of the whole tract, proposed to be
subdivided, as is shown on the plat and on all roads, streets and
avenues. Where the alleys and lot lines shown on the plat are not
parallel with the roads, streets and avenues, the courses and dis-
tances of such lines shall be put on the plat. The radii and chords of
all curved lines shall be shown on the plat by courses and distances
and their tangent points located by the coordinates hereinafter
defined. The plat shall show a meridian line drawn through one of
the corners of the outline or perimeter of the whole tract and another
line drawn at right angles to said meridian 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 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 these distances shall
be marked on the plat as the points where coordinates are required
by Sections 59 to 62. The plat shall show the coordinates for each
corner of each avenue, road or street intersection and the tangent
point of all curved lines shown on said plat, and shall show accurately
the dimensions of each lot. 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 body of water. The plat shall show the
position by coordinates of not less than four markers set in con-
venient places on the subdivision 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
subdivision 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,
