CONTAGIOUS DISEASES OP DOMESTICATED ANIMALS. 395 



Lord as follows : His Iiog-lot is ou high, dr}', aud bare ground ; contains 

 neither straw-stacks, rubbish, half-rotteu manure, nor pools of stagnant 

 water, and is kept as clean as practicable. Further, his hogs and pigs 

 are always confined to this yard, and are never allowed to run at large ; 

 they receive their water for drinking regularly from a good well, and 

 their food from a corn-crib, situated in the northeast corner of the hog- 

 lot. (I inspected his place afterwards, and found things exactly as 

 stated.) 



5. Messrs. Moir and Peterson several years ago were engaged in the 

 distillery business, and fed about 2,000 hogs. Their hog-pen, which is 

 still standing, but has not been used for several years, is three hundred 

 feet long, and situated close to the bank of the Mississippi. Swine 

 plague broke out among their hogs and caused a heavy loss. Several 

 times it subsided, or was temporarily stopped by a liberal use of chloride 

 of lime, employed not only as a disinfectant a,nd used externally, but 

 also fed to the hogs by mixing considerable quantities of it with the slop. 

 As soon, however, as the use of the chloride of lime was discontinued, 

 the disease invariably, in a,bout a week, broke out anew, and was just 

 as malignant as ever. The experiment was repeated several times with 

 the same result. Finally Messrs. Moir and Peterson conceived the idea 

 of dividing the long pen into a dozen separate apartments by putting in 

 partitions, but the feeding-trough, extending through the whole length 

 of the building, from one end to the other, and sloping gently toward 

 the west, was not divided ; the slop, as before, was let in the upper, 

 eastern end, and ran down through the whole length of the trough to 

 the lower, w^estem end, where, finally, the refuse was emptied into the 

 Mississippi. After this but very few cases of sickness occiuTcd among 

 the hogs in the upper or eastern divisions, which received the slop clean 

 as it came from the distillery, while in the lower or western divisions, at 

 which the slop arrived after it had passed through the upper and mid- 

 dle parts of the trough, and had been soiled and contaminated by all 

 the hogs in the apartments above, nearly every animal became affected 

 and died. In the lowest divisions not one escaped, while in the upper 

 ones no deaths occurred. It is, however, but justice to state that Messrs. 

 Moir and Peterson, finding much more sickness in the lower than in the 

 upper part of the building, soon commenced to use the lowest division 

 as a kind of hospital, and used it almost exclusively for sick hogs taken 

 out of the upper and middle divisions, which, of course, accounts to 

 some extent for the slight mortality in the upper and middle divisions 

 of the building, and explains why everv^ animal died in the lowest divis- 

 ion, but it does not account for the numerous deaths in the second, 

 third, and fourth lowest divisions. 



6. Mr. jSam. WMteman, near Eozetta, had swine plague in his herd a 

 year ago last vrinter, and disposed of every hog ?aid pig he could find 

 on the place. He intended to commence anew, and bought twenty head 

 of healthy shoats. After receiving them one dead pig, belonging to his 

 old herd, was found stiff and frozen in a fence-corner, where it had 

 died. It was immediately buried three feet deep, but in frozen ground, 

 and there the carcass remained frozen till the latter part of winter, when 

 it was found unburied and consumed by the twenty healthy shoats. 

 Ten days later the shoats commenced to die of swine plague. 



7. Captain William Morris, in Bald Bluff Township, near the county 

 line between Henderson and Warren, gave me the following informa- 

 tion : Kear his farm. Snake Greek empties into the north branch of Hen- 

 derson River. About two years ago somebody dumped two loads of 

 dead hogs into Snake Creek, six miles above its junction with the river.'
