Report of State Veterinarian. 69 



originated near Summerville, in Texas county. Few cattle were 

 left on the range at the time of the above investigation and no other 

 infection was found. 



We would recommend that a thorough investigation of the 

 herds in this vicinity be made early this year. We would also 

 recommend that inspections be made early this spring over the 

 territory and herds that are now held in quarantine, especially 

 along the Oklahoma state line. We are in constant danger of 

 ticky cattle drifting from infected territory in Oklahoma into Mis- 

 souri, also from cattle that might be driven across the line in 

 violation of our State quarantine. 



Oregon county was found free from infection and will remain 

 so unless infection is introduced from outside territory. 



Ripley county, as in the past, has caused us considerable annoy- 

 ance. Early in the spring of 1912 I made a trip to Doniphan and 

 made arrangements to meet the cattlemen of the infested district. 

 We talked over the situation and we finally persuaded them to build 

 two dipping vats for the dipping of cattle in the quarantine area. 

 I felt confident that we would be able to thoroughly eradicate the 

 ticks from Ripley county. In this we were very much disap- 

 pointed. While many of the cattle owners co-operated faithfully with 

 the State and federal inspectors, yet there were enough that were 

 indifferent and that refused or neglected to bring their cattle to the 

 vats on the date set to greatly hinder and delay our work of eradi- 

 cation. Much of the infection was carried through the winter by 

 the town cows of Doniphan. It will therefore be necessary to hold 

 the quarantine area in Ripley county over for another year. 



I would therefore recommend that the following area in 

 Ripley county be held under State and federal quarantine another 

 year: 



Congressional township 23 N., range 1 E. Congressional town- 

 ship 23 N., range 2 E. The north half of congressional township 



22 N., range 1 E, and the part of the north half of congressional 



23 N, range 2 E, which lies west of Current river. 



The above area can be easily inspected this coming year and 

 there is no reason why the quarantine should not be raised at 

 the end of the tick season, if the cattlemen will render the State 

 and federal authorities any assistance at all. I would recommend 

 that the following areas hereinafter described be released from 

 quarantine, except the cattle and farms that are now held under 

 local quarantine:
