This is one of the most valuable bulletins of the year, inasmuch as it deals with a new malady of one of our most important crops; or, rather, it is the first recognition of a very old malady, for "from observations now made, it appears that the disease is a very prevalent one, and probably has existed during the time that corn has been grown on the continent. If so, it has not ordinarily attracted attention and very likely is not destructive enough to be specially noticed. When, however, under peculiar circumstances, the crop is in-jured to the extent now sometimes known, the loss is very great, not only to individual farmers, but to the country at large".

The disease "commonly occurs in spots of various sizes, from a few square rods to an acre or more, and often, though by no means always, on soil of a character somewhat different from the rest of the field." Ordinarily the first indication of the disease is a dwarfed condition of the plants. Later the stalks become yellow and unusually slender, and sometimes the plant dies prematurely. Generally, however, the plants live during the season. "When some of the affected plants are pulled from the ground, they are found to give way too easily in consequence of the death, to a greater or less extent, of the oldest and lowest roots. In anything like severe cases, at least one-half the roots - always the lowest - are injured and usually dead. The bottom portion of the stalk is likewise affected and will be found dead or dying. If split longitudinally through the middle, the inner tissue of this lower part is seen to have a uniform dark color; and a similar discoloration, gradually becoming less and less pronounced, appears in the next succeeding nodes or joints. while the spaces between them (internodes) are seemingly healthy.

On the surface when carefully freed from dirt, brownish, corroded spots can be found, sometimes strictly bordered, again diffusely spreading Sometimes masses of semi-transparent, rather firm, gelatinous material are found upon these external corrosions." After midsum-mer the sheaths of the leaves become spotted and more or less gelatinous. At last the ears show the malady. "Externally, the appearance of the outer husks is like that of the diseased leaf-sheaths. Internally, in the worst stage, the whole ear - busies, which should be still green, young cob and kernels, and the mass of 'silks' - is reduced to a moist state of corruption, though not ill-scented. The parts lose their normal rigid or turgid quality, appear as if wilted, and are packed closely together, if not actually adhering by the gummy exudation from the tissues. Very often these ears subsequently become mouldy, penetrated through and through by a close, very white, felt-like fungus. Possibly this fungus sometimes makes its inroads into the ear without the bacteria as forerunners ; but from present knowledge it seems probable that it is a secondary intruder.

These mouldy ears are in certain seasons very numerous and are readily recognized by the husker, as well as by the buyer when the loads are sent to market".

The disease was first noticed so long ago as 1882, and in 1887 the author had made studies of it. There is some indication that it is associated with a virulent disease of cattle and an epidemic among chinch bugs. Dr. Burrill has inoculated healthy corn with the bacteria and has succeeded in producing the disease. The malady has been observed in many places in Illinois, in some cases destroying fields. It is yet too early to look for remedies. There is indication of "more injury on land which has been planted with corn the preceding year, though the rule does not always hold good".

January Garden, p, 53. This malady has prevailed here for many years. The description in the review corresponds exactly to the disease as I have seen it. But it works entirely on old corn ground. By rotating our crops of corn we avoid the disease. I have always thought that the disease was due to an insect, and am still of that opinion. An insect lays its eggs about the base or roots of the plant, and these eggs hatch out into hundreds of maggots. - W. F. Wing, Pueblo, Colorado.
