especially if these are made late in the season, a considerable 

 residue of arsenic and lead remains on the fruit at harvest 

 time. Authentic cases of illness from eating fruit carrying 

 these residues are difficult to find. Nevertheless, it is to the 

 advantage of the grower to have his fruit as free as possible 

 from such residues and to find substitute spray materials 

 which are effective but of a non-poisonous nature. The present 

 regulations of the Federal Food and Drug Administration do 

 not permit more than 0.025 grain of arsenic trioxide, 0.05 

 grain of lead, or 0.02 grain of fluorine per pound of fruit. 

 Certificates indicating amounts of residues are now issued by 

 regulating agencies in the various states. Notices sent to 

 growers take the following form: •
