authority space with their special punches. These tickets are 

 returned to the office by the recipient. They may well be white 

 to distinguish them from office tickets, which may be of two or 

 three different colors to indicate the relative urgency of the 

 work they authorize. 



Thus S-O. 789. Build 6 double axle lathes, 



might be on a yellow ticket, indicating a staple manufacture; 



and 



S-O. 2, P. Cut door north side pattern-shop, 



on a blue ticket, to indicate local work of an important nature. 

 Such tickets emanating from the office would be in ink, and 

 would refer to drawings, specifications, etc. ; but a merely local 

 order or foreman's request, such as 



S-O. 55, W. Stop leak in steam coil, 



sent, say, by the master carpenter to the master machinist, 

 might be in pencil on a white ticket. 



It is desirable, but not essential, that subordinate orders be in 

 writing. The advantage in definiteness, in responsibility, in the 

 certainty of execution, and in the accuracy of the record which 

 follow from writing them are so great as to outweigh the slight 

 loss of time taken to fill them up and punch them. A package 

 of tickets, a lead pencil, and a ticket punch are all that a fore- 

 man needs for attending finally to any order which he is compe- 

 tent to give. 



In complicated operations, where it is desirable to take heed 

 of the receipt of orders on their delivery, duplicate tickets, such 

 as shown in full, may be used to advantage. The duplicate 

 ticket is also intended for a complete exhibit, say, in the racks 

 of the superintendent's office of unfinished work ordered by him 

 or by his superiors. As the completed tickets come in from the 

 foremen, he takes down his retained copy from the proper rack, 

 punches it, and returns it to the main office, keeping that which 

 he has received on a file for future reference. 



Advantages of order tickets. 



Each foreman's unfinished work is always displayed before 

 him, relieving his memory and permitting him to apply all his
