Utility 



In this room the chief draughtsman and his assistant, the draughtsman 

 in charge of changes, the draughtsman in charge of allowance Usts and his 

 assistant, and the stenographers, have desks. The others each have a 

 table of standard form. Each table has a uniform arrangement and a uni- 

 form outfit of instruments, reference books, and supplies, with special 

 additions to the standard outfit for employees doing special work. The 

 arrangement of this table is shown in Plate 24. 



In this room in a gallery are the main current plan files, kept in metal 

 cases and under the charge of a special plan clerk. Owing to lack of space, 

 the considerable size of individual plans, and partly to the fact that it was so 

 started, these plans are filed, rolled, in pigeon-holes. Space does not permit 

 stowage of all plans, so only the plans of ships building and one or two classes 

 back (those most constantly referred to) are stowed here. The balance — a 

 very large number— are kept in fireproof vaults at the Washington Navy 

 Yard, from where a plan can be obtained twice daily by regular trips 

 established or in about half an hour in any emergency by the use of the 

 telephone. 



Under the gallery and in recesses along the wall, so as to give a smooth 

 waU surface, is a card index of all plans, whether stowed in the gallery or in 

 the Navy Yard vault. Here also is kept a card index of all photographic 

 negatives, of which a considerable number are taken for ships building. 

 The negatives themselves are kept at the Navy Yard.
