death the spleen is found to be greatly enlarged. The liver is enlarged 

 and of a darker color than in the normal condition. All of these things, 

 with the presence of ticks on the body, indicate clearly, to my mind, 

 the nature of disease that causes death under the above conditions." 



January 27, 1895, Mr. Hill wrote from Stockton, California: 



" Have just arrived here, and will likely stay here to-morrow, when I 

 expect to go eastward up the San Joaquin Valley, and will arrive in 

 Los Angeles about February 2d or 3d. One thing you can take to be 

 true, unless all the people in this part of California lie, and that is not 

 probable, to wit: that the country along the Pacific coast from the 

 Mexican line as far north as the Bay of San Francisco, and from the 

 foot of the Tehachapi Pass down the San Joaquin Valley to the Sacra- 

 mento River, is infested with ticks." 



Mr. Hill wrote from Ventura, California, to Colonel Dean, December 

 29, 1894, as follows: 



" Last night I stayed with Mr. L. J. Rose, Jr., at his home eight miles 

 from this place. He gave me the following history concerning his 

 cattle transactions during the years 1893 and 1894. I will give it in 

 his own language as repeated to me, to wit: In the spring of 1893, he 

 and William Hobson, a butcher of Ventura, California, leased what is 

 known as the Broome ranch, consisting of twenty-three thousand acres, 

 located seventeen miles southeast of Ventura. They also bought the 

 cattle on the ranch, seven hundred and fifty-five head. These cattle 

 had been raised on this ranch and there was an abundance of ticks 

 upon them, the ranch having been infested with ticks for years. This 

 ranch borders on the ocean, some of it not many feet above the sea level, 

 other parts high, rocky, and largely covered with small, bushy trees and 

 brush. Some of the peaks are from three thousand to five thousand 

 feet above the sea level. 



" Mr. Rose also had another smaller ranch, on which he had had more 

 or less cattle for three or four years. This ranch was also infested with 

 ticks. It is called the Tapo ranch, and is situated in the low mountains 

 south of Newhall and about thirty miles from the Broome ranch. The 

 lowest part of this ranch is about two hundred and fifty feet above 

 the ocean. This ranch is also rough, stony, and covered with under- 

 brush, etc., and much of it is from five to ten hundred feet above the 

 ocean, having many peaks much higher. To properly stock these two 

 ranches they first bought, May 15, 1893, five hundred head of cattle 

 from Mr. Hardison, who lives at Santa Paula, California, and they soon 

 moved two hundred of these to the Broome ranch and placed them with 

 the cattle already there. Within three weeks one hundred and seventy 

 of the Hardison cattle had died, and none of the cattle which were pre- 

 viously on the Broome ranch had been sick. About November 1, 1893, 

 they removed the remaining three hundred from the Hardison ranch 

 to the Broome ranch, and in three weeks one hundred head had died. 

 The Hardison ranch is near Santa Paula, about twenty miles from 

 the Broome ranch. Its elevation at its lowest places is from two hun- 

 dred to three hundred feet above the lowest elevations on the Broome 

 ranch. Mr. Rose assured me there were not, and never had been, any 

 ticks on the Hardison ranch, and others told me the same thing.
