Remarks. 



The descriptive symbols may be affixed to all member sym- 

 bols, as occasion may require, and new descriptive symbols may 

 be devised to suit new manufactures. 



Conversely, the descriptive symbols should be dropped when 

 the Shop-Order number sufficiently defines the object for which 

 the time or material is expended, or when their use in full would 

 give an erroneous idea of specialty. 



Thus, if Shop-Order No. 49 refers to making a certain number 

 of folded-head rifle ball cartridges, 49-A. I defines the particular 

 cartridge case quite as well as 49-F-R-B-A. I, and much more 

 briefly. For a similar reason powder is known throughout as 

 A. 21, and fulminate as A. 12; because these articles are com- 

 mon to all classes of ammunition. 



In referring to the cup anvil made for either the rifle or car- 

 bine cartridge, and noted in connection with the number of a 

 standing Shop-Order (Chap. XI), we would write it simply 213- 

 F-A. ii. If the pistol cup anvil were meant, we would write 

 2I3-F-P-A. n, reserving the general title for the more import- 

 ant ammunition.
