92 PROPOSED SYSTEM. 



requiring exact authentication. These punches are provided for 

 all those whose titles appear on the back of the correspondence 

 card ; their marks, like the abbreviations, are as soon learned by 

 all hands as are the owners' names. 



Stamps. 



Dating stamps are much used as a means of tracing delays, 

 etc. They are of the pattern of the ordinary line dater, consisting 

 of rubber type, printing as follows : " Mar. 16, 1884." They cost 

 only $2 complete, and should be at every foreman's desk. 



The stock clerk should have a consecutive numbering stamp. 

 When automatic, this can be bought for about $30 ; it runs up to

 stamp, combined with one indicating the entry by them of the 

 information given by the card.

Racks. 



These are intended for displaying single cards. They consist 

 of vertical wooden strips about I inch x | x 4 ft. long, with slanting 

 saw kerfs about I \ inches apart along the narrow edge, into which 

 the cards are slipped. The order rack for a large arsenal should 

 not hold less than 100 cards. It is conveniently placed against 

 the wall ; its topmost cards should be within easy sight and reach. 

 The strips should be grouped by shops, so that a glance will tell 

 what work is going on in each of them. 



Pigeon Holes. 



These are simply formed of a series of shelves about 4 inches 

 apart ; their width is one or two inches less than the length of 

 the cards to be contained in them. The compartments are 

 formed by vertical strips nailed against the face of the shelves, so 

 as to admit the cards freely between them. The back may well 

 be formed by the wall. 



Over each pigeon hole is partly gummed a target paster bearing
