SOUND REFLECTION. — Note and describe any places where this may be used to advantage 

 in navigation. 



SOUNDINGS. — Describe the character of the slope of the bottom and whether soundings 

 can be depended on to warn of the approach to danger or to enter ports in thick weather. Note 

 any special submarine features, such as valleys, escarpments, etc., that may be useful as submarine 

 landmarks. Off points and headlands note danger curve or sharply defined depth curves that are 

 of value in rounding such features. Where the character of bottom is of value to navigators, describe 

 in as much detail as necessary. 



STANDARDIZATION.— So far as possible the methods used in writing the Coast Pilots should 

 be standardized. Much time can be saved both in revising the Pilots and in preparing Supple- 

 ments, if all the Pilots are written in the same manner, as outlined. 



STARBOARD.— (See Port and starboard.) 



STEAMER AND LAUNCH SERVICE.— In isolated regions, all information available about 

 local steamer or launch service should be given. Describe the kind, whether passenger, automobile, 

 freight only, or combined. Any variation in service in the different seasons of the year must be 

 included. 



STORAGE. — If available, state the kind, whether covered, open, general, or cold. Are there 

 bonded warehouses? If small-boat storage space is available, give the size of the largest boat handled. 



STORM WARNING DISPLAY STATIONS.— List in appendix, and also note in place in text. 

 State whether there are day and night displays and if small-craft warnings are displayed. 



STYLE MANUAL. — This is issued by the Government Printing Office, and contains rules of 

 that Office governing the preparation of manuscript, and the correction of proof. Many examples 

 of compounding, phrasing, abbreviations, etc., are given and the writer should familiarize himself 

 with it and use it as a reference book. 



SUBMARINE BELLS.— Note and refer to Light List for details. 



SYMBOLS — Use the Symbols and Abbreviations chart published by the Bureau (see 

 fig. 189). 



TABLE OF CONTENTS. — The writer will find it advantageous to prepare a table of contents 

 with chart numbers, chapter by chapter, before writing the different chapters. 



Where the chart diagram is at all complicated, the areas covered by the largest-scale charts 

 should be outlined in colors on a copy of the small-scale chart which is the subject of the chapter. 



TABLES. — All tables, except for Directions and sometimes for bridges, should be in the appendix. 

 (See Appendix in 9135B(5).) In one of the Field Record Books a definite section should be set aside 

 for the assemblage of tables for the appendix. So far as possible, the tables are to be prepared in 

 the Office, and verified in the field. 



In the manuscript, each table must be shown on a separate sheet without any of the text appearing 

 on the sheet. This is a requirement of the Government Printing Office. 



TIDES AND CURRENTS. — Practically all the information relative to tides and currents is 

 furnished by the Division of Tides and Currents. All additional information obtained in the field 

 should be referred to that division for approval before publication. 



Information on tides and currents already published on charts and in tide and current publi- 

 cations should not be repeated in detail in the Coast Pilot. References to these publications are 

 important. If information is of special value, a general statement should be made. Peculiarities 

 and irregularities of tides and currents should be described. 



If the port or place being described is one of the standard ports for which daily predictions are 

 made in the Tide Tables or Current Tables, that fact should be explained in the Pilot. If there 

 are special publications by the U. S. Coast and Geodetic Survey, such as books or current charts, 

 dealing with tides and currents at any locality, they should be described in the Pilot. 



In shoal areas, especially in enclosed waters, give the variation of surface level due to storms and, 

 if possible, develop a relationship between velocity and direction of wind and the magnitude of result- 

 ing changes in surface elevation. 



Times of change of current, etc., should be referred to the time of high or low water at a port 

 for which tides are predicted in the Tide Tables, because the reader is apt to be more familiar with 

 tidal data. 



In discussing tidal currents, use the expression "current" rather than "stream." In describing 

 currents, consider carefully expressions such as "flood current," and "north-flowing current," and use 

 the one that best and most clearly defines the condition.
