LETTER OF SUBMITTAL. 
ARCHER, FLA., December 2, 1888. 
Sir: I have the honor to submit the following report upon the root- 
knot disease and its cause, the Anguillula. . 
These investigations, conducted under your direction, began in Feb- 
ruary, 1858, and have been continued to this date. 
While not conclusive in all respects, they are at least contributions 
to the history of this microscopic pest, that may eventually lead to its 
subjection or to the mitigation of its ravages. 
In conclusion, allow ne to express to you my thanks for your aid and 
guidance during the preparation of the report. 
Respectfully submitted. 
J. CO. NEAL, M, Ds, 
Speewl Agent.
