_Isolation. Movement from Infected Ground._ It has long been known that the movement of an infected herd from the contaminated pasture to another, will often, at once, check the development of new cases. In Sardinia and Auvergne the flocks and herds were yearly moved on the approach of autumn, from the rich valley, and bottom lands, to the drier hill pastures, to avoid or lessen the decimation that otherwise inevitably overtook them. This is in keeping with the enzoötic nature of the malady which arises more from the microbe preserved in the soil than from the sick animal direct. Two precautions are necessary in making such a change of locality: 1st, Animals already infected should not be moved on such new pasture; and 2d, the pasture to which the stock is moved should be entirely free from the impermeability (clays, hard pans), and saturation with water (swamps, basins, low bottoms), which would ensure the permanent preservation of any microbe planted there. Elevated, sandy, argilaceous or loamy soils are to be selected. To these the animals of the infected herd which by their appearance and thermometry may be pronounced sound, should be removed, and kept under careful supervision, especially as regards thermometric tests. Any showing symptoms of anthrax should be at once taken back to the infected herd. If they have stood in stalls, for milking or otherwise, these should be disinfected, and they should be carried in wagons, or driven by unfrequented roads. Their droppings should be carefully disinfected. If, in the absence of anthrax symptoms, animals must be kept in the infected lot, or returned to it, they should be immunized. _Interdiction of Sales._ No animal in the infected herd which shows a rise of temperature, should be sold even for slaughter. No animal should be sold for stock purposes until the disease has completely subsided. Any animal in the infected herd, which shows no hyperthermia nor other sign of anthrax, may be sold for immediate slaughter, subject to a critical expert examination of the cadaver for anthrax. Milk, the product of an infected herd, and butter and cheese made from such milk, should not be used as food. If those members of the herd, that show no hyperthermia or other symptom of anthrax, can be held apart as a separate herd, in a disinfected place and under careful thermometric observation, their dairy products may be used.
