THE SLIPKNOT EUBBEE HEEL. 



A new rubber heel has recently come on the market. This is 

 the "Slipknot," and the appropriateness of the name will be seen 

 from the accompanying illustration in 

 which it will be noticed that a slipknot 

 forms a part of the design. Not all com- 

 modity names involving a pun are to be 

 commended, but this one is a happy se- 

 lection, as it describes the character of 

 the heel and enables the name to be eas- 

 ily remembered. Another point brought 

 out by the accompanying cut is the raised 

 crescent-shaped section around the back 

 of the heel, which adds to its durability 

 and its non-slipping qualities. [Plymouth Rubber Co., Canton, 

 Massachusetts.]
