174 TICK RESISTANCE IN CATTLE 
These claims as set out read as follows :— 
1. That these cattle never mature more than a few odd 
female ticks during the course of a year—a total 
of from 50 to 100 per year being the highest esti- 
mate, though the animals are regularly infested 
(naturally) by myriads of larve, the majority of 
which die while still very minute. 
2. That as a result of such freedom from developing 
ticks, these cattle do not require any attention 
as regards ticks, and may be turned out on any 
country for indefinite periods without experiencing 
tick worry, and consequently present a clean, 
sleek appearance. 
3. That this pecularey, is transmissible to other cattle 
by “contact” (i.e., natural infection) and by 
vaccination, and is transmitted in every case to 
the progeny of such animals, but does not mani- 
fest its presence in the offspring until after the 
first year of life. 
With regard to No. 1, Mr. Pound stated that “ the 
observations as conducted on the question as to the number 
of ticks found on cattle at Mr. Munro Hull’s farm at Eumundi 
must be regarded as only of relative value compared with 
the definite and positive results obtained by Messrs. Watson 
and Carmody at Yeerongpilly, on which occasion the cattle 
were not artifically infested, the animals having heen 
brought from a ticky paddock and placed in stalls for con- 
venient and exact observations.” Judging from these 
remarks, he is evidently quite satisfied that the report of 
Messrs. Watson and Carmody is a sufficient answer to this 
claim. We propose to examine that report in detail. 
On May 12th, 1914, the animals were placed along with 
ticky stock in a paddock belonging to a Mr. Chambers, 
of Yeerongpilly, whose property was adjacent to Mr. Pound’s 
laboratory, where on June 8th they were brought into stalls, 
having been for 27 days exposed to infection. 
The following results are tabulated from Watson’s 
reports (R.S.C., pp. 31-2) regarding “ Tinkerbell,” one of 
the two animals; since in the other case, ‘Clover,’ no 
details were given. Only the number of mature ticks
