44 CITRUS TREES AND THEIR DISEASES 



exterminated a single pest or insect that preys upon 

 your fruit or trees? 



Fourth: If you know of any discovery of any 

 particular value that has been rendered to you by the 

 scientific bureaus or university, won't you be kind 

 enough to send the Doctor a letter stating what value 

 has been obtained from the scientific bureaus, as the 

 Doctor wishes to put himself right in the matter. He 

 already knows of some good things they have done, 

 and he does not wish to be unfair. 



What we need is more careful diagnosis of each 

 particular grove and a record book in which the grower 

 may keep a careful record of all conditions and also 

 all results of all treatments. This will quickly deter- 

 mine what the proper treatment of trees means. 



But keep this in mind, Mr. Grower, the body of 

 the tree is the life ; in fact it represents the entire tree. 

 Keep this body in good condition. So far nothing has 

 been discovered better than Doctor Messick's Tree 

 Tonic.
