The U. S. Coast and Geodetic Survey 



ant in charge of the office, prepares 

 replies for the Superintendent's signa- 

 ture to such parts of the correspondence 

 as falls within its particular field, and 

 also furnishes such information and 

 equipment to field parties as it is within 

 their power to furnish. 



In the computing division all com- 

 putations in connection with triangula- 

 tion, astronomical determinations, and 

 precise leveling are made, appropriate 

 registers of results are kept, and the 

 results prepared for publication as rap- 

 idly as possible. 



The magnetic division and the tidal 

 division deal similarly with the compu- 

 tations and publications of magnetic 

 and tidal results respectively. 



The drawing and engraving division 

 is divided into five sections : 



The photographing section, engaged 

 in reducing, enlarging, and reproducing 

 drawings for various purposes. 



The drawing section, engaged in mak- 

 ing from the original topographical and 

 hydrographical field sheets the office 

 drawings, which are the original from 

 which charts are produced, either by 

 engraving on copper or by photolithog- 

 raphy. 



The engraving section, engaged in 

 copper-plate engraving. 



The electrotype section, engaged in 

 producing from the original engraved 

 copper plates by electrotype process the 

 copper plates actually used in printing 

 the charts. 



The printing section, engaged in 

 printing charts from the copper plates 

 (the lithograph printing is done by con- 

 tract outside of the organization). 



The chart division is divided into two 

 sections. The hydrographic section is 

 engaged in completing unfinished hy- 

 drographic sheets sent in from the field, 

 in the correction of charts, especially 

 with reference to aids to navigation 

 (lights, buoys, etc.), preparation of 

 monthly Notices to Mariners in regard 

 to this matter, and the inspection of 



charts in their various stages of prepa- 

 ration. The chart section is engaged 

 in applying such hand corrections to 

 charts at the last opportunity before 

 issuing as has become necessary on ac- 

 count of such changes, principally in 

 aids to navigation, as have taken place 

 after the chart was printed, and with 

 the clerical work connected with the 

 issue and sale of charts. 



The library and archives division has 

 charge of the library of the Survey and 

 the archives in which all hydrographic 

 and topographic sheets and all the 

 original records and computations are 

 stored. 



The instrument division has charge 

 of all the instruments and general prop- 

 erty. Many of the best of the new in- 

 struments for the Survey are designed 

 and made in this division, and it is con- 

 tinually engaged in repairing and re- 

 modeling necessary to keep the instru- 

 ment outfit at a high standard of effi- 

 ciency. 



The miscellaneous division is charged 

 with the purchase and distribution of 

 all supplies required for use in the office 

 and of such supplies as are furnished to 

 field parties on requisition ; also with 

 the making of requisitions for printing 

 and binding, the custody of blank forms, 

 stationery, etc., and the distribution of 

 the reports of the Superintendent and of 

 all other publications of this Bureau, 

 with the exception of charts. 



As already noted, the accounting di- 

 vision, at the head of which is the dis- 

 bursing officer, is not a division of the 

 office in the sense of reporting to the 

 assistant in charge of the office. The 

 disbursing officer makes all disburse- 

 ments on account of the Survey, with 

 the approval of the Superintendent ; 

 renders a monthly account of all dis- 

 bursements to the Auditor for the Treas- 

 ury Department for audit by him, ren- 

 ders a statement of expenditures and 

 balances to the Superintendent when- 

 ever required to do so, suspends returns
