INTRODUCTION. 



INTERNATIONAL CONGRESS OF VITICULTURE 



SAN FRANCISCO, CALIFORNIA. 



July 12 and 13, 1915. 



The International Congress of Viticulture of 1915 was held at 

 San Francisco under the authority of the Permanent International 

 Commission, in accordance with a resolution of that body voted on 

 June 11, 1913, at Ghent, Belgium. At that time no one anticipated 

 that by reason of a world-wide war the European members would 

 be unable to attend. 



The international character of the Congress was preserved as 

 much as possible by the co-operation of the various countries con- 

 cerned, whose governments accepted the invitation to furnish repre- 

 sentatives from among their European commissioners. The members 

 attending the Congress and the papers presented were almost entirely 

 American. The absence of most of the active members of former 

 Congresses, and the lack of their valuable papers and discussion, 

 were serious deficiencies. The Congress, however, was valuable as an 

 indication of the progress and extent of viticulture in the United 

 States and the report should be of interest to the viticulturists of the 

 world as a symposium of American viticulture. 



The activities of the Congress consisted of meetings in San Fran- 

 cisco, at which the papers were presented and discussed, and of 

 excursions to some of the most important viticultural centers of 

 California. 



The papers presented covered a wide range of viticultural inter- 

 ests. They included seven addresses on historical, educational and 

 commercial aspects of viticulture; five on various cultural topics; 

 seven special regional studies representing most of the grape-growing 

 regions of the United States; fifteen studies of fungous diseases, 

 injurious insects and of methods of control ; nine papers on the chem- 

 istry, technics and products of viticulture and several miscellaneous 

 papers.
