ihorburn's 



Seeds 



For Sturdy Trees 



THE leafy shady maple on 

 the golf links, the tall 

 straight pine that makes 

 valuable timber for a hundred 

 industrial uses, the spruce 

 which the airplane maker 

 searches for with eagle eye, 

 the gnarled apple and the 

 heavy laden pear tree, whose 

 yields go to make such de- 

 licious preserves these strong, 

 valuable fruitful trees can only 

 be grown from the highest 

 quality seeds. 



Quality seeds are what we 

 specialize in. We've been 

 selling them for 116 years and 

 for satisfaction "there's noth- 

 ing like dealing with an old 

 established firm." 



Thorburn's tree seeds are 

 what you want. Today write 

 for catalog and price.
