THE GUIDE TO NATURE— ADVERTISEMENTS 



The "WOODLIFE " Idea Has 

 Come to Stay 



Architects, Painters, Decorators, Paint 

 Dealers, and the general public are all en- 

 thusiastic over Woodlife Shingle Stane — 

 the kind that is not ready mixed but has 

 Liquid and Colors separate. 



The architect can match any desired 

 shade. There are i6 beautiful and distinct- 

 ive colors. 



Painters and Decorators find it easier to 

 handle than White Lead and Colors in Oil. 



We are selling large quantities of Wood- 

 life because it costs less than one-third as 

 much as ready-mixed paint and lasts longer. 



A FIVE-YEAR GUARANTEE. 



In order to satisfy our customers as to 

 the reliability of Woodlife Shingle Stane, 

 we hereby guarantee that it will wear well 

 for at least five years on buildings to which 

 it has been properly applied. Should it fail 

 to do so, we will furnish new stain free. 

 The sterling quality of our product enables 

 us to give you this protection.
