(a) The profile line is monumented (discussed in Sec. Ill) so 

 that stadia are not used to establish the location of the instru- 

 ment; 



(b) a mental check is made of the one-hundreth place of each 

 rod reading as discussed in Section IV, 5; 



(c) a record is made of the number of paces walked by the rod 

 person between each survey point; and 



(d) the check discussed in Section IV, 5 is repeated as an addi- 

 tional check on the reduced data. Any errors should be checked 

 using the pace count. 



The stadia survey should not replace the standard rod and tape beach sur- 

 veying; however, it is superior to the Emery method and should be considered 

 when only two people are available.
