run with the disease. Furthermore, he said, the shipment of in- 

 fectious and contagious diseases in interstate trade is what this 

 bureau was established to prevent and not to encourage or con- 

 nive at, and it will undoubtedly not be long before the serum- 

 simultaneous treatment will be completely abandoned or pro- 

 hibited and the serum alone treatment established in its place. 



The same view was expressed by every other live stock sani- 

 tarian of prominence to whom the local situation was explained 

 — the fact that this Territory can be absolutely guarded against 

 the introduction of infection from abroad being the most obvious 

 reason for not introducing it in bottles, but to fight it with serum, 

 sanitation and segregation. In fact, the past year has seen a 

 strong turn of the tide among the veterinarians, practitioners as 

 well as ofificials, against serum alone and sanitation. Whether 

 the hog louse has any actual part in the transmission of cholera 

 from animal to animal has not as yet been established, but the fact 

 remains that thorough sanitation, with disinfecting hog wallows 

 and periodical dipping, seems in a number of cases to have kept 

 certain hog farms free from the disease even though all the sur- 

 rounding farms were infected. In the Breeder's Gazette of 

 September 16, 1915, Dr. Nelson, State Veterinarian of Indiana. 

 says : The more I see of vaccination and its results in a general 

 way the more I feel convinced that sanitation and not simulta- 

 neous vaccination is the solution of the hog cholera problem." 

 And in another part of the same article he says : "I rode 91 miles 

 one day last summer and that day did not visit any but sick 

 herds, all of them having been vaccinated by the simultaneous 

 method, being healthy when vaccinated, the loss ranging all the 

 way from 12 to 94 per cent." Preceding this statement Dr. J. W. 

 Connaway, chief of the Veterinary Department of the University 

 of Missouri, gives the following advice : "I would, therefore, 

 say to the young breeders and exhibitors, do not permit anyone to 

 use that little virus syringe on your show hogs nor in your home 

 herd. Do not permit anyone to bring onto your clean farm a 

 little bottle labeled "Viru.s— Danger" for that little bottle docs 

 contain elements of danger which you do not want scattered over 

 your farms. The inoculation of the contents of that bottle into 

 your hogs is liable to make some of them sick, and some of them 

 are liable to die, and the urine and dung from the sick hogs con- 

 tain cholera germs which it is not well to have scattered over the 

 premises. The scattering of this infection is planting seeds of 

 disease for future trouble." And in conclusion Dr. Connaway 

 adds : "The time is coming when there will be such a strong 

 lincu]-) of the agricultural ])rcss against the commercial use of 

 hog cholera virus that its interstate traffic will be ])rohil)itc(l. It 

 has been charged with carrying foot-and-mouth disease from one 

 state to another. It has done worse than this, it has been carry- 

 ing a disea.se that has cost the fanners of America vastly more 

 than the foot-and-mouth disease."
