saw on cattle in that valley. On the same carcasses, small ticks were 

 quite plenty. Afterwards, I found full-grown ticks on other cattle thai 

 died while I was there; also, on cattle that were put into a ehute for 

 examination. 



"I convinced Mr. Warren that ticks do exist in the San Joaquin Val- 

 ley, and in his locality. 



"I am of the opinion that they do not become very numerous, at hast 

 on those ranches in that section, for reasons which will be explained 

 further on. The cattle themselves showed that no great numbers had 

 been on their bodies; some animals examined, no ticks could be found, 

 or signs that there had been any, and in most cases I could only rind 

 from one to three on an animal, some full-grown and others small. On 

 this ranch they have lost by death about one hundred cattle during the 

 summer. Some of them were large, fat cattle, but in the main were 

 scalawags, i. e., have been ailing for some time." 



The information which is given above is certainly sufficient to show 

 that a large area of territory in California is permanently infected with 

 Texas fever. Many cattle have undoubtedly died from the disease in 

 that State. The cattle-tick, which disseminates the contagion, is found 

 in abundance there, and outbreaks of the disease have been caused in 

 other States by California cattle. The limits of the infected area in that 

 State have not been accurately determined, and further investigation 

 will be required to enable any one to make a line separating the infected 

 from the non-infected territory. With a large movement of cattle from 

 California to other States, it is necessary to have regulations which will 

 prevent the dissemination of disease with certainty, and the Department 

 can only consistently make the same regulations apply in the same 

 manner to California as they apply to other States for a like purpose. 



Very respectfully, 



1). E. SALMON, 



Chief of Bureau.
