TREATMENT OF CHOLERA 291 



measures usually established in connection with hog-cholera. It 

 is the usual custom where cholera makes its appearance in a neigh- 

 borhood to allow the shipment of all animals which do not show any 

 signs of the disease, provided they are moved to the shipping point 

 under proper precautions, to avoid spreading of the infection. 

 There is some question as to whether or not this should be permitted, 

 and from the scientific standpoint, at least, the Ohio regulations 

 are to be praised. From the practical side it may have a somewhat 

 different light, and in any great movement of this kind, where 

 general public co-operation is desired, it is necessary that we com- 

 bine the practical with the theoretic. 



However, as in these cases the exposed herds were at once 

 treated by serum alone or the serum-simultaneous method, free of 

 expense to the farmer, it is only reasonable that a strict quarantine 

 be required. Such quarantine should be estabhshed provided the 

 officials in charge of the work are sufficiently supplied with serum, 

 and have a sufficiently large working force to handle these exposed 

 herds promptly, otherwise it would be an injustice to quarantine 

 an exposed herd and forbid shipment during the incubation period, 

 as this would cause unnecessary loss. This is a measure which 

 must be worked out in each locality, and adjusted to best fit the 

 local conditions which exist in that particular state or locality. 



Placarding of Premises. — Two forms of placards are used in 

 Fayette County for farms on which swine are kept. One form is 

 used for the purpose of quarantine notice in the case of farms 

 which contain infected or exposed herds. The term "exposed," as 

 used in this connection, applies to any herd kept on a farm adjoin- 

 ing one on which cholera is present, and in which the two herds are 

 less than a half-mile distant. This quarantine notice, which is 

 reproduced on p. 292, is printed on yellow metal sheets, 10 by 14 

 inches in size, and is tacked up at the gateway entrances to these 

 farms from the public roadway. 



This notice served to warn anyone who was about to come upon 

 the premises that hog-cholera was present thereon, and of the 

 danger to their own herds which would result from their entering 

 this farm. Enforcement of this warning is provided for by a 

 suitable penalty, which will serve to stop any who might otherwise 

 be inclined to disregard the warning.
