On March 29th the best growth was in the unsteamed soil, the next best in the steamed soil to which the infusion was added, and the poorest in the steamed soil. The wheat was harvested on May 3, before it had begun to head. This period of about six weeks constitutes approximately the time re- quired for soil of this kind to recover sufficiently from the effects of steam- ing to give about the same growth of wheat as does the same soil un- steamed. The yield of crop was as follows:.
