Two armor d knights m mortal combat meet 

 Armed cap a pie— that 13 from head to feet 

 The helmet, breasti^late, shield and spear of one 

 Shone like the dazzling brightness of the sun. 

 The other suit of mail begrimed with rust 

 Was scarcely iiroof against his 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 Bl.a.ck-Mail 1" 



BEWARE OF IMITATIONS 



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

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