direction being read by a compass and the distance paced. The 
first method is more useful for areas of a few acres, especially if 
about a building. 
Method I 
In this method the plan should be plotted on a piece of paper 
ruled to squares; engineers cross-section paper is best. It is ruled 
ten spaces to the inch and each space may be taken as a foot, or as 
two feet, making the scale of the plan 10’ or 20’ to the inch, or more 
if desired. The sides of the main building give good straight lines, 
and their extensions may easily be located as they cross the grounds. 
Usually a building will give two such lines in each direction and 
sometimes more. When there is no building, a straight fence may 
be used as a base line, or three poles may be set up in line. Three 
will define the line at any point while if two are used positions on 
the line cannot be determined between them. A straight line on 
the ground, as a railroad-edge or ditch will do, but this is not so 
good as something which stands up so as to be easily seen. 
One of the heavy lines on the cross-section paper should be 
assumed as representing the base line on the ground, or two at right 
angles should be taken to represent the best defined sides of a build- 
ing. It will not be possible to locate the details of the building ex- 
actly by pacing and if special accuracy is desired for these measure- 
ments it will be better to tape them. This may be done by fastening 
the zero of the tape at one corner of the building and recording the 
readings at each side of windows, doors, etc., to the next corner, and 
similarly along the other sides. With this information the building 
may be easily plotted. 
Pacing is not sufficiently accurate to give good results by triangu- 
lar ties, even small errors in measurement will throw the intersec- 
tion of the arcs too far from the correct position. The pacing 
should be on 90° ties, that is along lines at right angles to the base 
lines. A point should be found in the base line where a line at 90° to 
it will pass through the object to be located. When the distance to
