KULE8 AND PEACTICES 25 



Descriptive terms in general are not charted. Colors describing painted objects are par- 

 ticularly undesirable because of their temporary nature. The name of the material of which 

 an object is built should not be charted, since the mariner cannot identify an object by its 

 material even at a short distance. 



The company's name on a tank, stack, etc., is omitted from the chart unless this name, 

 or the abbreviation of it, is visible on the landmark in letters large enough to serve as an identi- 

 fying feature to the mariner. Names of well-known buildings may sometimes be shown in 

 parentheses following the name of the landmark, as, DOME (STATE HOUSE). 



The large circle (2.5 mm) with dot in center (1-35, I-In) shall be used for recommended 

 landmarks that have been accurately located. The landmark style lettering, all capitals, shall 

 be used for both description and the name of the landmark, such as, STACK (TALLEST OF 

 THREE), HOUSE (WEST GABLE). A small ch-cle (1.0 mm) without dot (1-35, I-Io) shall 

 be used for landmarks not accm-ately located. Label the circle with capital and lower case 

 lettering, such as, Mon, Cup, Dome. The abbreviation "PA" shoiild be added when necessary 

 as a safety feature. 



When two similar objects are adjacent, and shown by two separate landmark symbols, the 

 word TWIN is omitted, but when they are indicated by one landmark symbol, the word TWIN 

 is used. 



When only one object of a group is to be charted, its name is followed by a descriptive 

 legend in parentheses, including the number of objects in the group, for example (TALLEST 

 OF FOUR) or (NORTHEAST OF THREE).
