Stations or objects cut in should be described at the time the fii'st cut is recorded 

 (248). Notations should indicate where the track between fixes should be taken 

 from the boat sheet (3352). Wliere positions outlining an area are recorded, a 

 description of the area shall be made, differentiating particularly between a reef and 

 a sandy low-water line (7824) . Sketches should be included of the more important reefs. 



A multitude of various miscellaneous entries are required, too numerous to be 

 discussed individually. 



Where notes are too long to be entered in the "Remarks" column, the sequence 

 of recording may be interrupted to record a note the entire width of the page.

The registration, at the end of the day, of the transmitted signal of any echo-sound- 

 ing instrument used shall be entered in the "Remarks" column.

8161. Statistics 



The statistics for each day's work shall be given at the end of each day, using rubber 

 Stamp No. 37, Statistics (fig. 182). Where a day's work is recorded in two volumes,

 The stamp provides columns for this division. (See also 124.) 



Echo soundings are not to be counted — note that the stamp specifically indicates 

 that only handlead and wire soundings are to be counted.
