These lines and few prominent points
within the corpora ton shall be con.
nected to form an accurate triangula-
ton system. From poinS in this sys-

by stellar observation, to which
the bearing of all lines within tho
corporation shall thereafter be
referred. The boundary limo of the
corpora tions and the boundary lines ex-
listing at tho time tho city was incor-

ticable and connected with the triangu-
lation system. skeleton survey shall
be made of the whole corporation con-
sisting OF locating points at or near tho
intersections of streets, points near i'm
portants objects and points rendered
necessary by the topography of tho
ground. This survey will DO connected
with the triangulation system and it's
object will be to ascertain the length
and bearing of lines connecting the
points. The points, together with the

. to the true location OF boundary lines
referred To i'll deeds. When the local ton
OF streets and alley lines has been de-
cided, monuments shall DO planted
throughout the city. Whenever, for
lack Of sufficient evidence, any street
or alley line cannot be definitely estab-

arbitration which shall consist of the
city engineer, disinterested person APP
pointed by the Hastings Court and the

monuments will be at the street
corners; in others at street centers;

ing to put them where they will be con-
venient for future use. and at the Same
time where they are not likely to be
disturbed. These will be referenced,
numbered, and recorded in the same
manner as the points of tho skeleton
survey and triangulation points. They
will be referenced by measuring the dis
lance to them from three local objcctsnot
in the same straight line. Levels shall
be run to establish accurate bench
marks throughout tho city. Levels
