178 TICK RESISTANCE IN CATTLE 
Mr. Pound (p. 39), stated that on the return of ‘‘ Tinker- 
bell’ to Yeerongpilly, after careful search, he failed to find 
any ticks, but that there was ample evidence of recent 
heavy tick infestation. also positive evidence that the cow 
had been treated with some arsenical compound. We have 
a letter from the Secretary of the above named Pastoral 
and Agricultural Society stating that the local Stock 
Inspector would not permit the animal to travel unless 
dipped. Consequently the presence of arsenic would be 
expected. 
In order to meet objections to our remarks relating to 
Mr. Hull’s so-called ‘‘ winter ticks ’’ and to the temperatures. 
of his animals during winter, one of us examined his herd 
in July last. The shade temperatures during the afternoon 
on 28th July were 72.2 degrees F., at 2 p.m., and 67 at 4 
p.m. The animals were either feeding quietly or rumin- 
‘ating in the paddocks, and were not disturbed in any way, 
so that the temperatures registered per vaginam can be 
regarded as normal. Opportunity was taken to inspect the 
cattle for the presence of exudate and ticks. Those marked 
‘*R”’ are considered by Mr. Hull to be tick resistant.
