Cable areas. — Include locations of termini. 



Overhead cable crossings. — Include clearances. (See 916, Aerial cables and trolley wires.) 

 Unusual characteristics. — Of shoreline, such as colored bluffs or other features that may be useful 

 as landmarks. 



Recommendations for new surveys. — These should be made in a special report to the Office. 



b. Submission of data. — The following procedure is recommended for submitting 

 information regarding changes: 



Note changes in the field on one set of charts, which set is retained by the reviser 

 for field use. 



Prepare a second set with notes relating to chart corrections. Cut these charts 

 into letter-size sections, and forward them to the Office with a transmitting letter 

 giving suitable explanations of the changes. After these are reviewed in the Division of 

 Coastal Surveys for future investigations they are filed as Chart Letters in the Nautical 

 Chart Branch of the Division of Charts. 



In preparing the set of chart-sections for the Office, the reviser should bear in 

 mind that landmarks, bridges, wharves, and other features cannot be applied to 

 the chart without actual location. Merely spottmg a feature on a chart is not sufficient. 

 An effort should be made to locate the features, at least by sextant angles. If time 

 does not permit this, and the feature is spotted or drawn in approximately, a note to 

 that effect must be made on the chart-section, with an explanation in the transmitting 

 letter. 



The reviser should indicate definitely whether the features noted on the chart- 

 sections were located or drawn with sufficient accuracy for charting. His judgment 

 in this respect is more valuable than an Office interpretation. He should furnish 

 all angles actually observed or state the method by which the feature was located. 

 All corrections and notes made on chart-sections should be in red ink. (See also 8521.) 



9134. Inspection of Chart Agencies 



During the course of his inspection, the reviser shall visit the chart agencies of 

 the Bureau to obtain and check information, and he will usually be required to make 

 a complete inspection of these agencies. Special instructions are issued for agency 

 inspections. 



9135. Preparation of Manuscript 



The manuscript for a new edition of a Coast Pilot is completed in the Coast Pilot 

 Section, except for stamping the type numbers, which is done in the Editor's office. 

 The manuscript may be prepared for printing either by cutting and mounting the 

 previous edition, or by typing. If the first method is used, the paragraphs should 

 be separated by 1 inch or more for the insertion of corrections, additions, and type 

 numbers. If the manuscript is typed, it should be double-spaced. Clearness will 

 reduce the cost of typesetting and result in fewer corrections to the proof. Where a 

 cross-reference is made in the manuscript, a memorandum should be made on the back 

 of the page indicating exactly to what the reference refers. 



The writer should be familiar with certain sections of the Style Manual of the 

 Government Printing Office, and with the "Instructions for Authors and Illustrators," 

 issued by the Division of Publications, Department of Commerce. If he is without 

 prior experience in the preparation of manuscript for the printer he will find it advanta- 

 geous to use an old manuscript as a guide.
