DEPARTMENT OF BOTANY
The imminent involvement of the United States in World War II demanded special duties for students and faculties. Carl LaRue was chosen by the USDA to procure fresh bud-wood of the Brazilian rubber tree from Bolivia, Nicaragua, and Mexico. He and Harley Bartlett, two decades earlier, had pioneered in the cloning of selected high-yielding rubber trees in Sumatra.
Bartlett went to the Panama Canal Zone in the summer of 1940 as botanist with the Gorgas Memorial Institute to attempt to discover the causes of increase in malarial-bearing mosquitoes. On his return to the States he was directly drafted to supervise the propagation of "the best Hevea (rubber) strains (in the Orient) and bring them to tropical America." In the summer of 1941 he succeeded in establishing plantations of choice Hevea clones in Haiti.
In September 1942, Bartlett began a "rubber-land-location assignment" in Mexico and South America which did not terminate until 1944. He supervised the introduction of plantings of the "rubber-bush," guayule, and the Russian dandelion, kok-saghz. This assignment was as much a diplomatic mission as a plant introduction project. It was his opinion in 1944 that "the future of guayule rubber appears very bright at this stage, at least as a hemisphere project, and the Congressional appropriations underwriting further development in many directions — one of which is improving methods for collecting the minute seeds — should greatly advance the culture of the plant in the Americas." In 1979 guayule cultivation again became news as the U.S. Congress legislated and funded for it an immense program in southwestern U.S. desert lands.
Frederick Kroeber Sparrow Jr., mycologist, showed ecumenical spirit in accepting an appointment with the Michigan State Experiment Station, growing milkweed for its floss, to be used in Army Air Corps uniforms. William Campbell Steere, bryologist, participated in the U.S. Cinchona Mission to Ecuador to procure quinine bark to compensate for the cut-off of supplies from the South Pacific. The mission was highly successful. William Randolph Taylor,
