would be cheaper and more practical to place new hogs upon new 
land and in new sheds, but when such cannot be done the above 
regulations must be rigidly executed if another outbreak would 
be prevented upon the same grounds.) 
7. In case such swine are placed upon new land great care 
must be taken that no person coming into any relation with them, 
or any teams used to convey food to them, cross the old grounds 
or come in contact with anything that may have been used among 
the diseased hogs. Tools, troughs and such things used among 
the diseased hogs should be burned and new ones provided for 
the fresh swine. 
8. Owners of hogs should be warned against performing 
themselves, or allowing other persons to perform, any surgical 
operation whatever (castrating, ringing the nose, tagging the ears 
or branding) upon their swine when the plague existed in the im¬ 
mediate vicinity or among their own hogs. 
9. Swine with wounds upon them or scratches should neither 
be placed upon previously infected lands or in such pens, nor 
among hogs in which the disease existed. All such swine should 
be at once removed from infected herds, if not already diseased 
themselves. 
The disposal of sick and dead hogs. 
1. No diseased or dead hogs should be removed from the in¬ 
fested premises. 
2. Cremation or burning the carcasses of dead hogs until re¬ 
duced to powder should be resorted to whenever and wherever 
possible. 
3. The carcasses of dead hogs should never be thrown into 
running streams, or so buried that the drainage from such burial 
places could possibly gain access to such streams or even to wells 
or ponds used to water stock. 
4. When cremation is impossible and burial has to be resorted 
to and the land is so situated that it can be done without conflict¬ 
ing with the previous regulation, a portion of the bog-yard or run, 
or land immediately adjacent to the same, should be fenced off 
with a solid board fence and a trench dug twelve feet deep and 
of a length corresponding to a space that would be occupied by
