LETTER OF TRANSMITTAL. 



U. S. Department of Agriculture, 



Bureau of Plant Industry, 



Office of the Chief, 

 Washington, D. C, April 7, 190J+. 

 Sir: I have the honor to transmit herewith a paper on "The Avocado 

 in Florida; its Propagation, Cultivation, and Marketing," and respect- 

 fully recommend that it be published as Bulletin No. 61 of the series 

 of the Bureau. 



This paper was prepared by Prof. P. H. Rolfs, Pathologist in 

 Charge of the Subtropical Laboratory at Miami, Fla., under the direc- 

 tion of Dr. A. F. Woods, Pathologist of this Bureau, but as the 

 subject is pomological rather than pathological, it was submitted to 

 the Pomologist with a view to its publication from his office. 



The accompanying illustrations are essential to an intelligent under- 

 standing of the text. 



Respectfully, B. T. Gallow t ay, 



Chief of Bureau. 

 Hon. James Wilson, 



Secretary of Agriculture.
