The plat at the left, subsoiled, shows the cotton mostly alive, and the plat on the right, prepared in the ordinary way, shows the cotton nearly all dead. the chedc plat which received ordinary preparation. The contrast was not so great, however, throughout 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 plowing 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 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
