Two armor'd knights in mortal combat meet 

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

 The helmet, breastplate, shield and spear of one 

 Shone like the dazzling brightness of the sun. 

 The other suit of mail begrimed with rust 

 Was scarcely proof against his f oeman's thrust, 





And after many a parry, guard aud lunge 

 He thought it wisest to throw up the sponge. 

 "See here," he cried, "thid 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-Hail 1" 



BEWARE OF IMITATIONS. 



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

 back such articles, and insist upon having just what you ordered.
