Excerpt from Guayule (Parthenium Argentatum Gray): Rubber-Plant of the of Desert the Desert In 1907 the author of the present paper was engaged by the Continental-Mexican Rubber Company and the Intercontinental Rubber Company to organize investigations looking toward the successful cultivation of a Mexican desert rubber plant, the guayule (Parthenium argentatum Gray). Dr. Theodore Whittelsey and Dr. J. E. Kirkwood later became identified with this undertaking, the former as chemist, the latter as assistant botanist. The headquarters for the investigations were established at the Hacienda de Cedros, Partido de Mazapil, Zacatecas, Mexico. It was not a matter for congratulation that, at the close of a year, the directors found it inadvisable, for financial reasons consequent on the panic of 1907, to continue the department of investigation. By the courtesy of the company, however, the author carried on his studies for some three months beyond the termination of his business relations with it, and this period, falling during the growing season of 1908, brought to light many important facts. Still further observations of capital importance, in part on experiments begun in 1907 and 1908, were made by the writer in April 1909, while representing the United States Rubber Company, a commission which could not have been prosecuted without the kind concurrence of President C. C. Thach and a number of the writers colleagues at the Alabama Polytechnic Institute. As silence was not imposed by the United States Rubber Company, it has been possible to include these observations. No less than hearty recognition is due also to Mr. W. H. Stay ton, formerly captain, U. S. Navy, sometime president of the Continental-Mexican Rubber Company, and now president of the Texas Rubber Company. It is stating an open secret to say that it was through the initiative and enthusiasm of this gentleman that the work of the investigation was undertaken and would have been continued but for circumstances beyond his control. Mr. Stayton has shown a liberal and scientific spirit, qualities not of necessity nor at all times associated. Thanks are due further to Prof. J. C. Arthur and Prof. W. G. Farlow for reports on various pathological matters; to Dr. M. T. Cook for contributing manuscript on the galls found on guayule; to Dr. A. D. Hopkins for a report on the guayule bark-borer; to Dr. L. O. Howard and Dr. J. G. Sanders for the identification of certain insects; and to Prof. B. L. Robinson for his courtesy in causing a photograph of the type specimen of guayule to be made. Mr. Charles S. Ridgway has rendered substantial aid in the preparation of certain figures. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
