California, Producer of Fine Seeds 
California grows more seed each year than any other particular section of the 
world. This is due to the fact that the long dry summers permit the proper 
ripening of seeds which would be spoiled by damp weather. 
Seeds Grown Under Supervision of Mr. Burbank 
All seeds listed in this book are produced in California, and are grown by in- 
telligent American labor directly under the personal supervision of Luther Bur- 
bank. It costs more to produce these seeds than the ordinary kinds, but it is our 
desire to produce only the very finest seeds that it is possible to grow. 
It goes without saying that Mr. Burbank selects the most ideal conditions to 
grow seeds having the most vitality and which will germinate under all ordinary 
circumstances. 
Germination Tests 
Exhaustive germination tests of all seeds are made IN THE SOIL, thus insuring 
the purchaser the highest percentage of seed which will germinate. 
For Protection of Purchaser 
To protect purchaser, a trade-mark seal will be on each package of seed— a copy 
of this seal appearing on the cover. This seal guarantees a genuine Luther Bur- 
bank production.
