:244 A TICK-KKSISTANT CONDITION IN CATTLE. 



because 1 have had many A-ears' experience Avith tick in- 

 fested cattle, that'Mr. Munro Hull has discovered a remedy 

 Avhich I believe would be the means of redu'cing the ravages 

 of the tick to a minimum aiid be of inestimable value to 

 farmers and others engaged in the cattle industry. In con- 

 clusion I would suggest that stock owners arrange Avith Mr. 

 Munro Hull for, say, four head of cattle and have a thorough 

 test by sending them to two districts where ticks are knoAvu 

 to be most actiA^'e and numerous." 



On January 21st, 1913, the coavs {i.e., experimental 

 :anima]s and controls) were remoA'ed, examined and officially 

 reported to haA^e sheAvn eA'idence of tick worry and tick 

 infestation. A number of fully-deA^eloped ticks Avere 

 removed from the cows, presumably Clover and Tinkerbell. 

 The fertility of these parasites and the vitality of their off- 

 spring Avas found to be normal. The cows were then re- 

 infested artificially with larA-al ticks (Pound, 1914, p. 110) 

 which matured and likcAvise showed unimpaired fertility. 



On May 12th, 1913, Clover was placed in a ticky paddock 

 at Oxlej^ : on June 14th she had a calf. On July 19th 

 both animals were found on examination to be tick 

 infested. In August, 1913, both coavs were sprayed (Thorn, 

 R.S.C., 1915, p. 29). 



In February, 1913, Mr. SAvayne, as Secretary of the 

 Parliamentary Farmers' Union, wrote to Mr. White- — then 

 Secretary for Agriculture — suggesting that the cows be sent 

 to Mr. Walker, M.L.A., and Mr. Corser, M.L.A. to see whether 

 ]\Ir. Hull's claim, that the cows remain free from tick in- 

 festation, would be demonstrated by a second trial in another 

 district and under different conditions. In September, 

 1913, this suggestion was carried out. Clover being sent to 

 Wetheron and Tinkerbell to Traveston. 



Clover. As the House was sitting Mr. Corser was away 

 much of the time, but a local committee was formed con- 

 sisting of members of the Wetheron Progress Association 

 and one of the men on the place. This Committee was 

 allowed to examine the cow at any time. Mr. Corser 

 inspected her on every occasion he was home and at no time 

 during the cow's stay at Wetheron was a developed tick 

 found on her (Corser, R.S.C., 1915, p. 61). Larval ticks
