W. A. Bates, of Lakeside. When giving evidence before 

 the Select Committee (R.S.O., 1915), on December 14th, 

 1915, Mr. Bates stated that he had had the cow under 

 observation for several months and that only tAVO or three 

 mature ticks had been noticed on her. She had never been 

 washed while his other stock had of necessity been treated 

 several times. He had not noticed an}' exudate. In reply 

 to a communication on this subject Mr. Bates wrote (January 

 28th, 1918) re Poppy • . . . In the two and a half 

 years 1 have had her, she has never been dipped or Avashed 

 and has been running with tick-infested cattle all the time. 

 She carries a few ticks at times but thev do not appear 

 to develop to anj" size. " He also mentioned that a calf 

 from Poppy ha-d not needed dipping up to the time of its 

 death (at about 18 months old). 



Pixie, born 1911 ; dam. Bluebell, sire, Peter Pan. 



This animal was loaned to Butcher and Re.\ when a 

 lieifer. Mr. Butcher (July, 1918), wrote that he failed to 

 ever find one tick on her during the whole time she was under 

 his care. She calved just before she was returned to Mr. 

 Hull. The calf (which he still had) had never been dipped 

 ior, like her mother, she never carried ticks. 



Vanity, born 1912 : dam, Bluebell. 



Butcher and Rex also had this animal. Mr. Butcher 

 wrote (July, 1918), "" Vanity we still have, she is a cow that 

 always did carry a fair amount of ticks, we never dipped her 

 and she would clean up again in a short while. We had a 

 steer from her but he was verj' susceptible to ticks and we 

 had to dip him regularly. We also have a young steer from 

 her but I tlo not know yet what his tick-resisting powers 

 will be." 



Communications were received from several persons 

 in the Xorth Coast district who had purchased stock from 

 Mr. Hull, in answer to inquiries as to the condition of these 

 animals as regards tick infestation. 



Mr. S. Kelly, Billi Park, P^umundi. Avrote (January 

 28th, 1918) that the one cow he had purchased had been 

 dipped regularly and Avas regularly infested with ticks. 



Mr. W. E. Xoble, Xorth Arm. wrote (February 2nd, 

 1918), that he had bought a Jersey coav from Mr. Hull : 

 She had retained her resistance. Two other cows became
