MAKSR OF 



fwo armor'd knights in mortal comtiat meet 

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

 The helmet, breastplate, shield and spear of one 

 Shone like the daz^ing brightness of the sun. 

 The other suit of mail begrimed with rust 

 Was scarcely proof against his foenian'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 Blace-Mail 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.
