DISEASES OF SWINE AND OTHER ANIMALS. ~ 383 
_ animals to be moved are sound and out of a healthy herd. lith. Rail- 
_ yroad and shipping agents at adjoining stations should be forbidden to 
. Ship pigs, excepting under license of the local authority, until the plague 
has been suppressed in the district. 12th. When infected pigs have 
been sent by rail, boat, or other mode of conveyance, measures should 
be taken to insure the thorough disinfection of such cars or conveyances, 
as well as the banks, docks, yards, and other places in or on which the 
diseased animals may have been turned. 
Other measures would be essential in particular localities. Thus in 
the many places where the hogs are turned out as street scavengers 
and meet from all different localities, such liberty should be put a stop 
to whenever the disease appears in the district, and all hogs found at 
large should be rendered liable to summary seizure and destruction. 
The great difficulty of putting in practice the means necessary to the 
extirpation of the disease will be found to consist in the lack of veterinary 
experts. No one but the accomplished veterinarian can be relied on to 
distinguish between the different communicable and destructive diseases 
of swine, and to adopt the measures necessary to their suppression in the 
different cases. In illustration I need only recall the numerous reports in 
which what is supposed to be hog cholera has been found to depend on 
lung worms, on any one of the four different kinds of intestinal round 
worms, on the lard-worm, on embryo tape-worms, on malignant anthrax, 
on pneumonia, or on erysipelas. To class all these as one and apply to 
all the same suppressive measures would be a simple waste of the pub- 
lic money, but to distinguish them and apply the proper antidote to 
each over a wide extent of territory would demand a number of experts 
whom it would be no easy matter to find. This state of things is the 
natural result of a persistent neglect of veterinary sanitary science and 
medicine as a factor in the national well-being, and must for a time 
prove a heavy incubus on all concerted efforts to restrict and stamp out 
our animal plagues. It will retard success under the best devised sys- 
tem, and will sometimes lead to losses that might have been saved, yet 
if an earnest and prolonged effort is made the obstacle should not be an 
insuperable one, and the United States should be purged not of this 
plague only, but of all those animal pestilences which at present threaten 
our future well-being. 
Respectfully submitted.
