THE ALEXANDER TRAP CLAMP. 121 



In order to use the teeth, first set the trap, 

 and, holding it with one hand, place the teeth 

 over the jaws with the other, allowing them 

 to rest on the jaws a short distance from the 

 ends of the treadle. 



The reader has already been cautioned 

 against springing the trap while the teeth are 

 on the jaws.
