report. Descriptions of, and recommenda- 

 tions on, new methods of field work, descrip- 

 tions of new instruments and equipment, and 

 similar subject matter should be submitted 

 as separate special reports, but the informa- 

 tion may be summarized in the season's 

 report. 



The following information and data should 

 be included in the season's report: 



(a) The project number and the name of 

 the officer submitting the report at the top 

 of the outside cover. 



(b) Dates of original and supplemental 

 instructions and of beginning and ending 

 field work. 



(c) A brief chronology of the activities 

 of the party. A detailed report of ship move- 

 ments during the field season is not desired. 



(d) The general organization of the party, 

 including a list of all officers and the general 

 capacity in which each was employed, giv- 

 ing dates of reporting or detachment. 



(e) A table of statistics on Form 21, Sta- 

 tistics and Summary of Field Work. 



(f) A brief summary of methods em- 

 ployed in executing the work, a discussion 

 of unusual methods used, and recommenda- 

 tions concerning continuation of the project, 

 when applicable. 



(g) An inventory of all computations, field 

 records, hydrographic and topographic sur- 

 veys, either completed or uncompleted, in- 

 cluding any already forwarded to the Wash- 

 ington Office or to a processing office, and 

 any remaining on hand from previous seasons. 



(h) The season's progress sketch in ac- 

 cordance with 2-46. 



(i) A separate progress sketch showing 

 only the triangulation. 



2-46 Season's progress sketch. — A prog- 

 ress sketch on tracing cloth, summing all 

 the information shown on the monthly prog- 

 ress sketch, shall accompany the season's 

 report. The monthly progress sketch may be 

 used for this purpose, if desired. The title 

 should state "Progress Sketch to Accompany 

 Season's Report" and should include the date 

 of closing field work in addition to the 

 information in the title of the monthly prog- 

 ress sketch. 



Any triangulation executed by the field 

 party shall be shown on a separate sketch 

 also attached to the season's report. The tri- 

 angulation sketch shall be prepared in ac- 

 cordance with instructions on pages 191 and 

 192 of Special Publication No. 247. 



2-47 Annual statistical report. — An an- 

 nual statistical report shall be submitted by 

 each Chief of Party as of June 30 of each 

 year on Form 40. This report must not be 

 delayed, and shall be forwarded not later 

 than July 10. Statistics only are required, 

 the information being needed for inclusion 

 in the Director's Annual Report. A separate 

 report must be submitted for each project. 

 The person who is Chief of Party on June 30 

 shall submit this report for the entire fiscal 

 year, regardless of the length of time he has 

 been chief of that party. 



An annual progress sketch shall accom- 

 pany the report. The sketch shall be made 

 on tracing cloth with maximum dimensions 

 of 8 by 10 Va inches. The scale of the sketch 

 must necessarily be small and some informa- 

 tion must be generalized to show area cov- 

 ered. A separate sketch is required for each 

 project. 



2-48 Objects for use in locating aids to 

 navigation. — Personnel of United States 

 Coast Guard tenders use the three-point fix 

 method, wherever possible, to locate floating 

 aids to navigation and to replace them on 

 their stations (see 5-80). For their use in 

 this work a special chart shall be prepared 

 by each hydrographic party on which shall 

 be shown the objects, natural or artificial 

 best suited for this purpose. 



During the survey each floating aid to 

 navigation which can be located by a sextant 

 fix shall be visited for the purpose of select- 

 ing by inspection the most suitable objects. 

 These need not be restricted to landmarks 

 recommended for charting; if there is an 

 insufficiency of these in the most appropriate 

 locations, they should be supplemented by 

 less prominent objects, visible from the re- 

 spective aids, and located specifically for this 

 purpose. Permanent objects not likely to be
