the lands with the owners' names so far as they can be learned, that
will be affected thereby, and such other information as they may have
collected that will tend to show the correctness of their findings.

81D. The Board of County Commissioners shall consider this re-
port at their first meeting. The engineer and other two viewers being
present. If the viewers report that the drainage is not practicable or
that it will not benefit the public health, or any public highway, or be
conducive to the general welfare of the community, and the Board of
County Commissioners shall approve such finding, the petition shall
be dismissed at the cost of the petitioners. If the report of the viewers
is favorable to the project and the Board of County Commissioners
shall so find after hearing all the evidence, they shall make such rec-
ommendations as they think proper to the viewers, and direct them to
make a complete survey, plans and specifications, and estimate of cost
for the tiles, drains or levees, or other improvements, and fix a time
when said engineer and viewers shall complete and file their final re-
ports, not exceeding sixty days, unless extended by the commissioners
in writing.

81E. The engineer and viewers shall have power to employ such
assistants as may be necessary to make a complete survey of the drain-
age district, and shall enter upon the ground and make a survey of the
main drain or drains and all their laterals. The line of each ditch,
drain or levee shall be plainly and substantially marked on the ground.
The course and distance of each ditch shall be carefully noted and suffi-
cient notes made, so that it may be accurately platted and mapped, A
line of levels shall be run for the entire work and sufficient data secured
from which accurate profiles and plans may be made for each of the
proposed drains or levees. Frequent bench marks shall be established
along the line, on permanent objects, and their elevation and full
description recorded in the field books and their location shown on the
map. If it is deemed expedient by the engineer and viewers, other
levels may be run to determine the fall from one part of the district
to another. If no old water course, ditch or channel is being widened,
deepened or straightened, it shall be accurately cross-sectioned, so as;
to compute the amount of cubic yards saved by the use of such old
channel. A drainage map of the district shall then be completed, show-
ing the location of the ditch or ditches and other improvements, and
the boundary, as closely as may be determined by the records, of the
lands owned by such individual landowner within the district. The
location of any railroads or public highways and the boundary of any
incorporated towns or villages within the district shall be shown on
the map. There shall also be prepared to accompany this map a pro-
file of each levee, drain or water course, showing the surface of the
