DISEASES OP SWINE AND OTHEE ANIMALS. 155 



recovered ; seven now sick. Symptoms : diarrliea, prostration of strength, 

 tympanitis. Dissection of one hog one year old showed great emacia- 

 tion, tympanitis, little change in liver, Inngs, spleen, and kidneys. 

 Bovrels were expanded with gas, and there were a number of nlcers sit- 

 uated at seat of solitary glands. The disease was typhoid fever. Ko 

 treatment was attempted, as the man refused to follow instnictions ; but 

 the slowness of i)rogress under the rather unfavorable circumstances 

 showed the slight contagion there is in typhoid, as merely turning the 

 drove out on aVafferent pasture had alone checked the rapid progress 

 of the disease, although sick and well remained together. 



John Y. Anderson, WasMngton, Iowa. Poland-China herd ; on grass 

 and away from straw or manure when attacked. Soil, black loam ; wa- 

 ter, open ditch j intense heat, 99° F., at time of attack in July ; disease 

 in near vicinity, and had been in this herd three weeks. The owner had 

 lost seventeen hogs, fifty-eight shoats and pigs, and had remaining 

 thirty-eight hogs and three pigs. The disease had spread gradually, and 

 was killing two or three per day. The symptoms were the same as in 

 last drove — pale, large, and flabby tongue ; diarrhea ; tympanitis. All 

 sick. I ordered milk and lime-water, and ground cooked feed made into 

 slop, and limited quantities of soda bicarbonate and hyiiosulphite (each 

 five pounds), sulphite iron (one pound), given at the rate of one pound 

 to drove of thirty-eight hogs twice a day. Mr. Anderson reported that 

 all the sick animals recovered except three pigs, two of which were sac- 

 rificed in tlie cause of S/cience. This man did not allow in-breeding ; no 

 scrofulous taint was detected in dissection ; he did, however, use rings, 

 which I consider were the ])redisposing cause of the disease in this herd. 



W. J. Hamilton, Washington, Iowa. Breed, Poland-China; feed, 

 growing rye and dry whole cOrn, with slough water for drinking. Pens 

 clean, largo range, but soil black loam, and rings used in nose. The 

 disease had continued ten days, during which time ten had died and 

 thirty-five had been attacked. ' Dissection of a. few of the sick showed 

 tubercular disease, and the gentleman stated that he had been in-breed- 

 ing for some time. The same treatment was adopted as in the last case, 

 but rei^ort showed no beneficial results when used with sick hogs, or in 

 preventing the spread of disease. 



Amana" Colony, Homestead, Iowa county, Iowa. Breed, Poland- 

 China; pens in poor 6rder ; feed, corn and slop. No disease had been 

 known in the colony for twelve years. In July the agent purchased in 

 Iowa City five boar pigs, and they were hauled to depot and forwarded 

 on cars to Homestead when it was intensely warm. On arrival one of 

 the pigs refuseil to eat, and was put in a small pen in breeding-house, 

 where it died a few days afterward. On the fourteeutli day tlie hogs in 

 pens on each side of the one occupied by infected liog were taken sick 

 and died, and the disease gradually extended until over two hundred 

 had died. Two of the five boars were sent to the North Amana Colony, 

 and in five days refused food, sickened, and died; and in nineteen, days 

 from their arm-al the pigs in pens on eacli side of the one containing 

 sick boars were taken sick and over five hundred died in a few months. 

 In each of these cases the disease appeared lirst only in the pens imme- 

 diately adjoining the infected pen, and afterwards spread to the other 

 pens. ' The other boars were carried to the other colonies of the society, 

 remained well, and no disease appeared in any of the seven settlements 

 except the two mentioned. I visited tlie man IVojn whom the boars were 

 purchased, but could elicit but ver\"little information. He stated that 

 his ^^ hogs had coiigh, as all hogs had, and that lie had lost about thirtj'- 

 five head by the intense heat, they being very fiit, but that no disease
