LETTER OF TRANSMITTAL 



Porto Rico Agricultural Experiment Station, 



Mayaguez, P. R., January 20, 1909. 

 Sir: I have the honor to transmit herewith a manuscript by H. C. 

 Henricksen and M. J. Iorns on the subject of pineapple growing 

 in Porto Rico. 



The data reported herein have been secured by the former hor- 

 ticulturist of the station, H. C. Henricksen, and the present one, M. J. 

 Iorns. over a series of years. They have also visited other pine- 

 growing sections of the West Indies and Florida. By comparison of 

 methods and results many valuable lessons have been drawn that will 

 be of benefit to this industry in Porto Rico. Besides a study of the 

 local conditions, especially of the soils of the island with a view to 

 their use in producing this luscious fruit, they have also made some 

 original studies of the peculiar requirements of successful pineapple 

 production. 



I respectfully recommend that this manuscript be issued as Bulle- 

 ( in No. 8 of this station, and that it be published in both English and 

 Spanish. 



Respectfully, D. W. Mat, 



Special Agent in Charge.
