appearance. [ recoiuinemled a chaiijje of pasture and water; tlie hog- 

 pens to be removed and the boards used for some other purpose ; the 

 old hocf pasture to be plowed ui), and seeded with wheat or other grain 

 for at least two years before it should again be used for a hog pasture. 

 I also advised a destruction of all the hogs that, indicated plain symp- 

 toms of the disease, and afterwards an entire change in the breed or 

 family of hogs. I inclosed in a tin can a ])ortion of tlie Inng, liver, in- 

 testine, and stomach of the pig examined, and sent it to your De[)art- 

 ment by express, for microscopic examination. 



After my return to Wellington I saw Mr. Hamilton again, when he 

 told me that he aud his partner, Mr. Flint, lost 10 or 17 head of their 

 cattle out of yOO head. Their pasture is feuced in, aiul is located in the 

 corner of Kingman, Pratt, and Barbour Counties, and comprises 30,000 

 acres. This pasture held Texan cattle last year. The cattle this year 

 in the field were not exposed to other cattle. The disease appeared in 

 the month of September ; 10 or 12 that were sick recovered. Changing 

 pasture and water seemed to oft'er a check to the disease. 



1 returned to Harper in the night. On the 23d it rained hard all day, 

 and I remained in town, I saw I. J. Campbell, esq., who gave me the 

 following history: He owns h fenced pasture ou the western edge of 

 town. On the 10th day of April Mr. Boyd placed 14 head of lame cattle 

 in this field, which already containetl 150 head of natives owned by Mr. 

 Campbell : the Boyd cattle remained for a week or more to recuperate, 

 and were then driven by the way of Pratt's to the Boyd range. Some 

 time during the month of July 2 steers that were brought from the 

 northern part of the county were turned into this field ; soon thereafter 

 both sickened and one of them died. The steers in coming to Harper 

 crossed a number of cattle trails. N'one of Mr. Campbell's cattle died. 

 Mr. R. A. Jones, from Labette County, told me that while on a visit to 

 his brother at Santiago, Cal., last year, his brother told him that cattle 

 that were brought from Old Mexico and driven north into colder and 

 freezing climates in California impart disease to native cattle. 



October 24 we drove southwest 16 miles to see Mr. Richard Botkin. 

 He held cattle belonging to Shafer, Coyer, Arnold, Collins, McMullen, 

 and Martin, the total number being 502 head. All of them were native 

 cattle except the McMullen cattle, which were brought from Webster 

 County, Missouri, reaching Botkiu's range in the month of May, and 

 remained until the 1st of Sei)tember. Dr. Wisner took away 120 head 

 of them, and the remainder were sold to and taken away by Mr. Pctter. 

 The Boyd cattle passed over his range in April, and all of these cattle 

 have been grazing over their trail. All the deaths in this herd which 

 occurred while on the Botkin range took place between the 2d of July 

 and the middle of August. Loss, 184. Mr. Campbell, at Otega, lost 

 one work ox out of a yoke of oxen in the month of July. 



Munger Brothers, of Flarper, started from Harper in the month of 

 May 10 thoroughbred and high-grade bulls; by mistake the driver
