CHAPTER XIII. 

 WHISTLE SIGNALS. 



The whistle can be made to do service if its 

 use is rightly understood, but it is very poor practice 

 to toot and blow it promiscously without any plan 

 or method. If all threshermen would adopt and 

 use a prescribed code of signals, those connected with 

 the machine would soon become accustomed to them 

 and understand what they mean. 



The less the whistle is used the better, as it scares 

 high spirited horses, excites persons not accustomed 

 to it, and attracts the attention of all within hearing 

 from their work. This time lost would not be very 

 much for one man, but twenty-five or one hundred 

 men losing from one-half to noe minute apiece, is an 

 item which if multiplied often during the fall's run 

 will be of enough magnitude to deserve attention. 



CODE. 



One long continuous sound is given to attract atten- 

 tion at such times as in the morning or at noon to 

 indicate the working place. 



Two long continuous sounds with a short interval 

 between them is to denote the work completed for 

 that day or at that place, as the case may be. 



One short sound is to stop.
