CITRUS TREES AND THEIR DISEASES 49 



benefitted by this book or not. The writer has taken 

 great pains to set up nothing in this book that is not 

 a demonstrated fact; therefore the great enjoyment 

 and pleasure that the writer would receive from the 

 knowledge that his book has been appreciated, would 

 be of untold value to him in his blind condition. 



Therefore, the writer wishes the reader much 

 profit and blessing from the lines herein. The re- 

 sults, I will leave to you. Careful obedience of the 

 rules in this book will bring them forth. 



FORMULAS 



The writer has decided to give with each book, 

 three formulas, as follows: No. 44 is a dry humus 

 and mineral fertilizer; No. 55 is a root extract; No. 

 66 is a pruning paint. 



As these formulas have no equal so far discovered, 

 and go in harmony with Messick's celebrated Tree 

 Tonic, they are very valuable indeed. This Tonic has 

 been used on more than 25,000 citrus trees. On ac- 

 count of the blind condition of the author, and his poor 

 health, he is unable to manufacture the three formu- 

 las mentioned above. 



This is the greatest value ever handed down to 

 citrus growers; these formulas and the book of in- 

 formation, all for $1.00. These formulas will not be 

 printed in the book, but will be delivered upon receipt 

 of the signed application on the last page of this book. 



The purchaser of the book will kindly read his 

 book, fill out the blank and address same to Dr. H. L. 

 Messick, Pomona, Calif.
