REPORT OF THE FEDERAL HORTICULTURAL BOARD. 



United States Department of Agriculture, 



Federal Horticultural Board, 

 Washington^ D. 6'., September 30, 1918. 

 Sir: I submit herewith an executive report covering the adminis- 

 tration of the plant quarantine act for the fiscal year ending June 

 30, 1918. 



Respectfully, 



Hon. D, F. Houston, 



Secretary of Agriculture. 



C. L. Marlatt, 



Chairman of Board, 



LINES OF WORK. 



The principal lines of work under the plant quarantine act during 

 the fiscal year ending June 30, 1918. are as follows: (1) The pink 

 bollworm work, including the cotton-free zone and quarantine work 

 in Texas, the border quarantine and disinfection service as to cars 

 and freight from Mexico, and the research work in relation to the 

 life history and habits and means of control of the pink bollworm 

 conducted in cooperation with Mexico near San Pedro in the Laguna 

 district, Mexico; (2) the regulation of the entry of foreign cotton 

 lint, waste, cotton bagging, etc.; (3) the regulation of the entry of 

 nursery stock and other plants and plant products for propagation ; 

 and (4) the enforcement of the miscellaneous foreign and domestic 

 quarantine and other restrictive orders listed at the end of this 

 report. 



The personnel of the board and its principal administrative officers 

 remain the same as last year. Owing to war conditions the board 

 has lost many of its efficient inspectors in both local and field service. 

 The pink bollworm work in Texas and on the border has necessitated 

 a very extensive addition to the quarantine inspection force. Port 

 inspection offices are maintained at Boston, New York, Newark, San 

 Francisco, Seattle, Calexico, and all of the border ports between 

 Mexico and Texas. The occasional needs of other border ports and 

 of the interior ports of entry are met for the most part by State 

 officials acting as collaborators of the board. The board has con- 

 tinued its cooperative relations with the State, Treasury, and Post 

 Office Departments of the Federal Government, and with State in- 

 spection and other officials. Many of the last have been appointed 

 collaborators of the board. 



Some of the more important activities of the board are discussed 

 in the following pages.
