TRAVERSE. 33 



the actual change in latitude or departure (longitude) 

 is desired, it may be computed with the traverse table. 

 In platting with the protractor care should be used 

 that all the angles are set off from the same meridian, 

 otherwise the errors will accumulate. The angles of 

 all courses in surveying are measured from the north 

 and south cardinals toward the east or west, and they 

 should be platted the same. The figures on some pro- 

 tractors are misleading in this respect.
