 Armed cap-a-pie— that is, from head to feet. 

 The helmet, breastplate, shield aud spear of one 

 Shone like the dazzling brightneaa of the sun. 

 The other suit of mail begrimed with rust 

 "Was scarcely proof against hia foeman's thrust, 



And after many a parry, guard and lunge 

 He thought it wisest to throw up the sponge. 

 "See here," he cried, "this isn't fair, you know. 

 Your armor's polished with Sapolio. 

 I cannot see to fight — I'm sure to fail — 

 Sapolio protects you from Black-JIail !" 



BEWARE OF IMITATIONS. 



Grocers often substitute cheaper goods for Sapolio to make a better profit. Send 

 back sucli articles, and Insist upon having just what you ordered.
