the second mode of prevention is, to choose the hog fence onapart of the farm, which consists as nearly as possible all of thesame kind of soil. On such a pasture, it is said the braxy isnever destructive.

The next mode of preven-tion is the method of herding. Let them be stopped on theupper parts of their pasture for two hours in the morning;and by all means, let them not be suffered to remain too late onthe grassy parts below, but again put in motion outwards, thatthe stomach may not be impaired by too immoderate fills ofthis soft grass.

The water settles sometimes in one corner of the skull, andsometimes in another; but wherever it begins, it continues toincrease and gain upon the brain until it is either extracted,or till the animal perishes, at which period the brain is com-monly half wasted away, and the skull full of noxious fluids.Sometimes it concentrates in the ventricles of the brain, andin the hinder parts, where it joins with the spinal marrow',in both of which cases it is deemed incurable. But in the
