separately and marked for the attention of the Coast Pilot Section. Important infor- 

 mation should be forwarded at once, but the general report should be submitted at 

 the end of the season. In all cases where information in the Pilots is found to be 

 accurate and adequate a statement to this effect should be included in the notes. 



Coast Pilot notes should be complete, clear, and accurate. Any sailing dii'ections 

 should be checked before inclusion in the report. 



856. Geographic Name Report 



Where practicable, a special report on geographic names shall be submitted to 

 cover the project area, or that part of it surveyed during the season. Where only one 

 hydrographic sheet comprises the project, the information may be included in the 

 Descriptive Report (see 8i2R). The information to be included in the report is 

 described in detail in 163, and other information of value in composing the report 

 is contained in section 16, 



In case the project area has recently been covered by air photographic surveys 

 and a geographic name report has been submitted in connection with that project, 

 duplication is to be avoided. Only new information which is disclosed and names in 

 the water area which were not investigated by the air photograpliic party should be 

 included, 



857. Ranges for Compass Deviations 



In addition to showing on the smooth sheet, in accordance with 7845, all useful 

 ranges of natural objects and those established by the United vStates Coast Guard, a 

 special report should be made for each project or season's work, of prominent and 

 easily distinguished objects and ranges that are suitable for use in determining devia- 

 tions of ship magnetic compasses and errors of gyrocompasses. 



The report should include a description of each object, its latitude and longitude, 

 and its intended use; special emphasis should be placed on how to identify it with 

 certainty from the area where it will probably be observed ; the azimuths of all recom- 

 mended ranges should be included, with a statement as to how each was determined. 

 Instructions for obtaining azimuths of ranges by planetable and sextant are contained 

 in 3833. 



Mention should be made in this report if any azimuths from wharves were deter- 

 mined in accordance with 356, and to whom the results were given. 



858. Special Reports 



Special reports on other subjects, which are of broad scope or interest and which 

 are not restricted to the survey or the season's work, should be submitted from time to 

 time. Each of these should be written as an entity and under no circumstances should 

 such information be included in either the season's report or a Descriptive Report. 

 Each of these reports should be entitled "Special Report on {subject matter) by (author's 

 name)." It should be approved and forwarded by the Chief of Party, Among the 

 many subjects which should be treated in this manner a few are specifically mentioned 



8581. New Methods and Equipment 



All members of survey parties should be encouraged to study the principles involved 

 in hydrographic surveying and to experiment with new methods and apparatus. De- 

 scriptions of new methods and apparatus, and suggestions for the improvement of those 

 in use should be furnished as separate reports.
