lang: Major Kelley, Senator Downey and Dr. D. Spence. Dr. Spence advocates the planting of the seed thick in the spring and harvesting in the fall, and states that his experiments show that he could get 1170 pounds of pure rubber per acre, which he maintains can be produced at a great deal less cost, and a great deal quicker, than under the transplanting plan.
