lang: Another original machine, which Bud Spencer is driving, loosens the dirt around the nursery plants when they have been topped. The roots go straight down for eight to twelve inches and this operation makes it simple for the laborers to gather them, one of the few hand processes in the growth of guayule. Dr. David H. Spence, Stanford University rubber chemist, maintains that the cheapest way to grow guayule is to harvest the plants when they are at this stage. William O'Neil, General Tire's president, believes this system should be adopted for emergency development of a rubber supply.
