ened danger from other sources. The local stockbuyer is a valu- 

 able gobetween for the farmer in marketing small lots of hogs, 

 but he becomes a nuisance and menace if he forms the habit of 

 seeking for bargains in diseased and badly exposed herds. He 

 thus aids in maintaining infected pens at the local stockyards, and 

 carries infection on his shoes to healthy herds and clean farms. 



The owners of healthy herds should keep stock-buyers out of 

 their hog-lots, if they have come from infected premises, and 

 have not properly disinfected their shoes. Stockbuyers should 

 join the farmers' anti-hog-cholera clubs, and do everything they 

 can to aid in eradicating cholera by applying proper sanitary 

 measures. It will serve their own business interests in the best 

 possible manner. 



Cholera infection may be carried to healthy herds and farms 

 by teams and wagons. Threshing outfits that go from farm to 

 farm should be careful to not drive through cholera-infected hog- 

 lots, or in fact through healthy hoglots. Inquiry should be made 

 as to the presence of cholera on the farms where threshing is 

 done. Every precaution should be taken by every man on the 

 force to avoid coming in contact with the infection, and to pre- 

 vent the teams and wagons from doing so. When hogs are 

 hauled to the local stockyards it is a wise precaution for the 

 farmer not only to disinfect his shoes but also to disinfect the 

 feet of the team, and the wheels of the wagon, before returning 

 to the farm, especially if sick hogs have recently been unloaded 

 in the local stockyards. Also disinfect the inside of the wagon- 

 box, and the litter it may contain. 



HOG RAISING IN HONOLULU AND VICINITY. 



Immediately upon my return from San Francisco, an effort 

 was made to ascertain the present status of the hog industry in 

 and around Honolulu. If cholera was present an opportunity 

 to test the Haring method on a small scale might be found, and 

 if not it was desired to learn exactly to what extent hog raising 

 had recuperated since the epidemic of 1911 when the Moiliili 

 district was almost cleared of hogs. Dr. Case was therefore re- 

 quested to make inquiries regarding hog raising at all farms and 

 dairies where the tuberculin testing took him and special trips 

 were made to those districts where hogs are always raised on a 

 small scale. On Mr. Charles Bellina's farm at Kuliouou, one of 

 the two places where cholera was prevalent last spring, every- 

 thing was found highly satisfactory. There boiled swill is fed 

 with alfalfa and no disease of a suspicious nature has appeared 

 for several months. Good litters averaging from 5>^ to 6 is the 

 order, the pigs being treated to a small dose of serum a week 

 or ten days after birth and to a full dose at the time of weaning. 

 As no virus has been used it is obvious that the infection, unless 

 carried by some of the survivors from the last outbreak, must by
