this opinion as of little consequence, for the reason that such as are fede 
for pork do not afford a sufficient lapse of time to clearly demonstrate 
this point; and, on the contrary, among breeding animals that are — 
allowed to live elder, in which timely opportunity is given, our informa- — 
tion is that a second attack is not an unusual occurrence. te 
HEREDITARY EFFECT OF THE DISEASE. 
Females having the disease when breeding almost invariably cast 
their young. If they escape that accident, the offspring usually die — 
very soon after birth. Subsequent litters from the animal, after com- 
pletely recovering from the disorder, do not appear to be wanting in 
vigor, and do not exhibit a greater aptitude for the disease than other 
animals.

“PREVENTION OF THE DISEASE. 
The widespread prevalence of the disease, its rapid course and dread- 
ful fatality, warrant the opinion that measures of prevention, if discov- — 
ered and applied, will be much more beneficial in resultithan the discovery 
of a successtul line of treatment for the disease, unless that treatment _ 
shall consist of some specific remedy, a practical use of which can be © 
made by the farmers in all stages of the complaint. 'Thatsuch a remedy 
will be discovered, we are of opinion, is not within the range of proba- 
: 
bility. The measures necessary to prevent disease in domestic animals iS 
embrace within their range a careful study of their natural habitsand 
wants, and a strict observance of the laws of health that governall — ws 
animal life, the principles of which are the same in their. application to 
the inferior animals as toman. Those errors alluded to when considering = 
the cause of the disease, as, in our opinion, largely contributing to, if 
not wholly the cause of, its development, must be corrected. The idea 
that swine are exempt from the ordinary laws governing health, and 
will thrive under any and all circumstances, must be abandoned. Forced o 
to keep pace in his superior development with the civilization oftheage = 
in which he lives, he requires additional care in his managementin 
order to ward off the numerous ills to which he is liable, many of which 
were unknown to his race in its unimproved state of nature. The food ‘ 
of the animal should, at all times, consist of the greatest possible” = 
variety; the water drank should be strictly pure; too many animals . 
should not be herded together; the young animals should be kept to a 
themselves; frequent change of locality, by shifting from one field to = 
another; the frequent plowing up or burning over of the lots usually . 
denoted as hog-lots in order to disinfect them; frequent change of 
sleeping-places, and the removal and destruction of old, filthy bedding- — 
material. During the dry fall months, when the swine are running ab 
large, they should be daily inspected, and at the approach of that period 
when the succulent grass is giving place to the mature and dry, laxative 
food, such as bran-mash or oil-cake; or aperient medicine, as linseed-oil 
or Glauber salts, given to counteract the constipating effect of the dry 
grass; the watering-places daily inspected; if running in open fields 
with high weeds and grass, they should be taken out at night and kept 
from the cold, wet grass, and turned into woods, if there is such a place 
available; they should be kept from weedy and stubble fields during the 
dry dusty period of the fall season, both day and night. When confined 
in close pens, these pens should be cleaned daily, and disinfected when 
there is stench, by the use of copperas, chlorinated lime, or with dry,
