table is set a compass. This table is
arranged to mount on tripod. and has
very ingenious dwelling arrangement.

Vey' the engineer sets up the plane table
at the starting point, sights along the
road, notes the exact compass course, UNI
i'm oers the tripod, gets into his buggy
and says "g'long' TO the old mare The
arrangement on the wheel keeps tab on
the distance and he drives ON until the
road changes its direction. Then he gets
out, sets up the tripod and makes a mark
on the paper to correspond to the dis
lance and direction Travelled. It's a very
small mark, but 1t counts. Then the new
course is taken, and the procession moves
on.
Some roads, as the reader we'll knows,
are more prone to change direction than
are others, and so II was that the surveyor
upon occasion had to alight from his
chariot twenty times or more in going Il
single mile. while occasionally he had
benefit III the way Of long stretch OF
straight highway. Mr.. Madden says
that his horse had the business learned SO
well that she would stop when the direct
ion OF the road changed, aud that II he
was minute or two longer than usual in
making his notes, she would look around
to see what he was doing.
The mapping Of the lakes ana ponds is
done by plane table work, but an assistant
IS needed " ho carries the rod and equip
ment and does the rowing when boat is
used. In making map OF pond start
is made at any convenient point and the
rodman is sent ahead to the first point OF
variation from comparatively straight
line. The direction and distance are
noted and indicated on the table. The
surveyor then goes beyond the rod TO the
next point and sights back. thus getting
two observations at each setting up Of the
rod. But trnmping around pond shores is
hard work at best, over rocks, through
swamps and in many places boat has
been found Indispensable. The plane
table shows many sided figure and
represents body OF water bounded by
mathematical shores. As the engineer
proceeds he sketches the deviations as
near the natural line as possible.
Every cove, point and island is noted,
and when the entire sheet has been skirted
there must be perfect course, that
