ROUTINE OF DUTIES IN THE DIFFERENT DEPARTMENTS. 

 ROUTINE OF DUTIES IN THE DEPARTMENT OF ARCHIVES. 



Koutine duties "From this department are issued the Hydrographic No- 

 Department, tices and Notices to Mariners, an officer being assigned to 

 this duty. To facilitate the work, one copy of each Admi- 

 ralty and United States Hydrographic Office chart is kept 

 in the Archive-room, arranged in cases and with index- 

 books and boards showing the shelves upon which they are 

 arranged. All other foreign charts are also kept in this 

 room for reference. 



The following method is pursued in getting out Hydro- 

 graphic Notices and Notices to Mariners : 



When foreign notices, or information which is intended to 

 be published, are received by the Assistant Hydrographer 

 from the Hydrographer, they will be sent to the head of the 

 department of Draughting, who will examine them to see if 

 Foreignnotices they apply to the charts upon which he is working. He will 

 scrutinized, &c. then return them to the Assistant Hydrographer, who will 

 have them carefully examined to see that they have not 

 already been published from this office. Those that have 

 not been published will be prepared for the printer, and the 

 charts will be examined to see that no errors have been 

 made in the latitude and longitude of places, and in bear- 

 ings and distances. The bearings in these notices must be 

 magnetic ; those in foreign notices, with the exception of 

 the English, are generally true. Care will also be taken 

 that the orthography of proper names is correct. 



When the notices are prepared for the printer they will 

 be registered in the book prepared for that purpose, and 

 will be inclosed in an envelope addressed to the chief clerk 

 of the Bureau of Navigation, and a blank requisition will 

 also be inclosed. 

 Notices issued The envelope unsealed and inclosure will then be sent to 

 the librarfan. y the librarian, who will docket them in the ' Record of printed 

 matter sent from the Hydrographic Office.'
