a disease incident to sheep, arising from wet seasons, and too moist pasture. It is a very hard thing to prevent the rot, if the year prove very wet, especially in May and June. Salt-marshes, and lands where broom grows, are the best places of preservation for them. Sheep are sometimes all cleared of the rot, when not too far gone with it, only by removing them into broom-fields. Scurvy-grass, mustard, parsley, and thyme, are also good for the prevention of it.
