The contrast was not so great, however, througliout the whole area. It was impossible to obtain satisfactory photographs of the plats treated by deep fall plowing, as the leaf worm had destroyed the foliage. TREATMENT RECOMMENDED. The benefit derived from deep fall jjluwing is so remarkable that it seems desirable to call the attention of cotton growers to this method of controlling the root-rot. The deep fall plowing should 102-V.
