Mar showing counties from which outbreaks of Hog Cholera or
Swine Plague were reported to the Board during the past year.

These two diseases, affecting animals that are the basis of an industry representing millions of dollars, and suffering annual losses of over half a million dollars due, chiefly, to the ravages of these diseases, are not receiving, and cannot receive, the attention that they should be given by the State Board of Live Stock Commissioners until provisions are made for carrying on the work in an effective manner. The control of hog cholera and swine plague requires large funds and, with these, intelligent and willing co-operation on the part of the owners of swine. At the present time there is manifested a tendency, on the part of many owners, to suppress information regarding the appearance of these diseases in their herds, rather than to aid the Board in locating them. The explanation of this is apparently the fear entertained by the owners

of affected animals that any measures that are enforced with a view to controlling the diseases will necessarily result in a pecuniary loss to them. While this is true in a certain sense, in a few cases, it is certainly not so when a broader view is taken of the subject.

After either of these diseases lias affected an animal, that animal, in all probability, will be a total loss to the owner. In most cases the diseases are incurable, and the neat of a diseased animal ought not to be considered as fit for human food.

The Board is endeavoring, as in the past, to aid the swine breeders and feeders of the state in controlling these diseases by inviting the owners of infected herds to report outbreaks as soon as they become known and receive in return advice and assistance, where the latter can be given, that will lead to the saving of at least a part of the herd, and that will tend to check the progress of the disease among those of their neighbors.

It has been shown that the introduction of certain sanitary measures will do more toward saving a large part of an infected herd of swine than any medicine yet discovered.

A bulletin on the prevention of swine plague and log cholera was issued by the Board some time ago and copies of this are sent to all persons applying for the same, or who request information that it contains.

The above map shows the distribution of these diseases, by counties, as far as outbreaks have been reported to the Board during the past year.

Infectious Keratitis of Cattle: Map showing counties from
which the disease has teen reported durine the past year.

During the warm season, especially in the latter part of summer, this infectious eye disease is frequently reported. It affects the eyes of cattle and usually remains strictly localized. The course of the disease is short and usually terminates in perfect recovery within a few weeks. In a small per cent. of cases there may be permanent impairment of sight, or even complete loss of one or both eyes.

On the whole the disease is not considered a dangerous one, the loss occurring from it, as a rule, being confined to slight and temporary loss of flesh by the afflicted animal.

Owners reporting the existence of the disease in their herds are advised to isolate the affected animals, and to treat their eyes with an antiseptic wash. No further regulations for the control of this discase are advised by the Board.

Nodular Disease in sheep.
Map showing, by counties, the localities from which Nodular
Disease in sheep (oesophagos toma Columbiana) has been re.
ported during the past year.

Not many years ago nodular disease in sheep was unknown in Ohio; it is now reported more frequently from year to year and is becoming very destructive to sheep in several sections of the state. The disease is caused by an intestinal parasitic worm (Oesphagostoma Columbianua), which causes the appearance of various sized nodules (hence the name) in the walls of the large and small intestines of affected animals. Young pregnant ewes seem to suffer more than other sheep.

The disease frequently terminates in death, and in other cases it permanently affects the general health of the animal. Once introduced
