munication whatever with any diseased hogs or pigs is cut off in every 

 respect, which is absolutely necessary, and still danger should be antici- 

 pated, for instance, if one or more animals should have become infected 

 l)efore the herd was removed, or a po.si5i))ility of either food or water for 

 drinking being or becoming tainted with the infectious principle should 

 exist, the danger may be averted, or at least be very much diminished by 

 administering three times a day to the water for drinking either some 

 carbolic acid (about 10 drops each time for every 150 pounds of live 

 weight) or some hyposulphite of soda (a teaspoonful for every 100 

 pounds of live-weight), till all danger has disappeared. Second, where 

 swine plague has been allowed to make some {)rogress in the herd, or 

 where the presence of the disease is not discovered until several animals 

 have been taken sick or have died, and others have become infected, the 

 best that can be done is to separate at once the healthy animals from the 

 diseased and suspected ones ; to place the healthy animals by themselves 

 and the doubtful ones by themselves; to separate, disinfect and treat 

 the animals in the way just stated. Special care must be taken to pre- 

 vent any communication, direct or indirect, between the three different 

 parts of the herd. If one person has to do the feeding, etc., he must 

 make it a strict rule to attend always first, to the healthy animals, then to 

 those considered as doubtful, and last to the sick ones, and must never 

 reverse that rule, or go among the healthy hogs or pigs after he has been 

 in the yard or pen occupied by the others. If possible each portion of 

 the herd should have its own attendant, who should not come in contact 

 with any of the others. The separation must be a strict one in every re- 

 spect; even dogs and other annuals may carry the infectious principle 

 from the diseased animals or from the yard occupied by them to the 

 healthy hogs and pigs. Buckets, pails, etc., which are used in feeding 

 the sick hogs should not be used for the healthy ones, because the infec- 

 tious principle may be conveyed by them from one place to another. 

 Last, but not least, it is very essential that the hog-lot occupied by the 

 healthy portion of the herd be higher than that occupied by the others. 

 If it is lower, and especially if it is so situated that water and other liquids 

 from the other hog-lots can flow into it or over it, the separation is 

 worse than useless, for then the healthy portion of the herd will surely 

 become infected, unless the ground is exceedingly dry. Third, whenever 

 swine plague is prevailing in the neighborhood, any operation, such as 

 ringing, marking by wounding, or cutting ears or tail, and castration and 

 spaying particularly, must not be performed, but should be delayed until 

 the disease has disappeared, or does not exist anywhere within a radius 

 of two miles. If such operation should become absolutely necessary, the
