1291 57 STAT.] MEXICO-RUBBER INVESTIGATIONS-- July 10, 1943 Sept. 20, 1943 SUPPLEMENTAL MEMORANDUM TO THE AGREEMENT BETWEEN THE SECRETARIA DE AGRICULTURA Y FOMENTO OF THE UNITED MEXICAN STATES AND TIlE DEPARTMENT OF AGRICULTURE OF THE UNITED STATES OF AMERICA Under the terms of the existing agreement between the Secretaria de Agricultura y Fomento, Mexico and the Department of Agriculture, United States of America, dated April 11, 1941, and in accordance with An t , p. 1282. agreements supplemental thereto, the Governments of the United Mexican States and of the United States of America have established a program of rubber plant research and government demonstration plantations for the development of a Hevea rubber plantation industry in Mexico, and have initiated also a cooperative experimental program on Cryptostegia. During 1942 the United States Department of Agriculture has Production of gua- greatly expanded its program of investigations of guayule and has undertaken an extensive program of guayule production. In coopera- tion with the Secretaria de Agricultura y Fomento of the United Mexican States a few indicator plantings have been established in Mexico. As a consequence of work conducted during the past year the United States Department of Agriculture now has a sufficient supply of guayule seed of high rubber-yielding strains to permit a limited expansion of its guayule program. To implement the desire of the Governments of the United Mexican States and the United States of America to develop a source of crude rubber, it is the mutual wish of the Secretaria de Agricultura y Fomento of the United Mexican States and of the United States Department of Agriculture to cooperate in undertaking the investiga- tions necessary to determine the suitability of areas in Mexico for the cultivation of guayule, and through assistance to private cooperators in establishing plantings of guayule for the production of rubber. Accordingly, in recognition of the common interest of the Govern- ments of Mexico and of the United States in the cultivation of guayule for rubber production, the following Supplementary Memorandum is hereby agreed upon: A. THE DEPARTMENT OF AGRICULTURE OF THE UNITED STATES Text of memoran- AGREES: 1. To provide at its expense guayule seed or seedlings of improved Seed or seedlings. strains of high rubber-bearing capacity for the investigations con- templated under this agreement. 2. To conduct extensive surveys for the purpose of broadly delineat- Surveys. ing the location and extent of areas within which it is believed guayule may successfully be cultivated. 3. To develop and maintain at its expense, on sites selected in Experimentalplant- cooperation with the Secretaria de Agricultura y Fomento of the United Mexican States, experimental plantings believed to be repre- sentative of areas where guayule may successfully be cultivated. 4. To conduct, except as otherwise provided in this Memorandum, Research. at its expense the research necessary to achieve the purposes for which each experimental planting is established.
