LETTER OF TRANSMITTAL. 



Porto Rico Agricultural Experiment Station, 



Mayaguez, P. R.^ October 15, 1911^. 

 Sir: I transmit herewith a manuscript on Fungus Diseases of 

 Ck)ffee in Porto Eico. 



The seriousness of these troubles from the standpoint of one of the 

 leading industries of Porto Rico justify the studies herein set forth, 

 and the methods suggested for combating the diseases, which are 

 now causing enormous losses, should be widely disseminated among 

 the planters of the island. 



I respectfully recommend that this manuscript be issued as Bul- 

 letin No. 17 of this station and that it be published in both English 

 and Spanish. 



Respectfully, D. W. May, 



Special Agent in Charge. 

 Dr. A. C. True, 



Director Office of Experiment Stations,

Recommended for publication.
