products to that country. 
It was prepared by Harry B. Shaw, plant-quarantine inspector, in charge 
of Foreign Information Service, of the Division of Foreign Plant Quarantines, 
from the French and German texts of the corresponding Swiss laws and regu- 
lations, and reviewed by the Division of Agriculture, Federal Department of 
Public Economy of the Republic of Switzerland. 
The information contained in this circular is believed to be correct and 
complete up to the time of preparation, but it is not intended to be used inde- 
pendently of, nor as a substitute for, the original texts, and it is not to be 
interpreted as legally authoritative.
