stations; and temporary topographic and hydrographic stations used in ship hydrography. 



(3) Names of three letters — temporary topographic and hydrographic stations used in 

 small-boat hydrography; and ordinary survey buoys. 



Where the inshore hydrography precedes the ship hydrography, the requirements 

 of rules (2) and (3) shall be complied with as far as practicable. The small-boat 

 party shall anticipate, if possible, the stations likely to be used by the ship, and assign 

 four-letter names to them. 



2152. Selection of Station Names 



To avoid confusion in the records, names should be selected that can be spelled 

 and pronounced in only one way. The use of combinations of letters that are pro- 

 nounced the same as other more common words but are spelled differently, should 

 be avoided. For example, TAK and TUN should not be used because they are pro- 

 nounced the same as TACK and TON, respectively. 



The hydrographer should keep current an alphabetical list of names as they are 

 adopted for use on his sheet. All three-letter names must be selected from the list in 

 table 42 in 965. Copies of this list can be obtained from the Washington Office and 

 can be used as a check list of assigned names. A study of this list will also be helpful 

 in the correct selection of four- and five-letter combinations. 



2153. Assignment of Names on the Hydrographic Sheet 



So far as practicable and insofar as it does not conflict with other provisions herein, 

 the control stations on a hydrographic survey sheet shall be assigned names that 

 proceed alphabetically along the shoreline from left to right as viewed by the hydro- 

 grapher during his survey. The names shall be so selected that the one at the approxi- 

 mate midpoint of the survey begins with a middle letter of the alphabet. 



Where ordinary survey buoys are used for control, the names shall be arranged 

 alphabetically for each line of buoys to satisfy the above requirements as nearly as 

 practicable. 



Such an arrangement of names has many advantages, both during the survey 

 operations and during any future use of the survey sheet where quick identification of a 

 particular station is necessary. 



This method of assigning names does not supersede the general principles of 

 naming stations outlined in 215(c), (d), and (e). 



2154. List of Stations in Sounding Records 



An alphabetical list of the stations used on a hydrographic survey sheet, together 

 with their origins, shall be prepared and pasted in volume 1 of the Sounding Records^ 

 following the title page. The list should be in the following form:

When a triangulation or traverse station has been used, the complete name with
