22 /. A. Gilruth : Cattle Tick ami Tirk Fever. 



2. This is the only importation of native Eastern cattle which have 

 been able to cross with station cattle. 



3. These cattle we know travelled inland as far as the Adelaide 

 River. 



4. It is more than likely some of their progeny would gradually 

 reach from there the main stock route from the South to Darwin. 



5. This point would be somewhere about Glencoe. 



6. At Glencoe about eight years after the introduction of these 

 Eastern cattle, redwater as an epidemic and serious disease first 

 appeared in Australia. 



7. The disease redwater only affected travelling non-immune cattle 

 on reaching Glencoe. 



8. The evidence strongly points to the gradual spread of ticks and 

 redwater to other parts of the continent along the stock routes from 

 this point, b)^ cattle which had l)een sick and recovered, tending to 

 travel backwards in the direction of their original home, and in this 

 way difrseminating the ticks.
