Life History ‘This is being carefully followed up by skilled investi- 
of gators at the University grounds in Brisbane, and at ex- 
Cattle Tick. perimental stations at Woolooga and Toowoomba. The 
main object of the work is to determine the length of 
time taken by the tick to pass through its different stages. 
This has an important bearing on the question of 
quarantining infected animals. 
Sheep-fly Investigational work is being carried out at Wooloon- 
Pest. dool, near Hay, in New South Wales, and at.Dalmally 
Station, in Queensland, and large numbers of parasitic 
wasps, which destroy the pups of the sheep-fly, are also 
being bred and distributed. The New South Wales and 
Queensland Governments are co-operating. 
Castor Oil Forty acres are being grown in an experimental way 
Beans. at Cockatoo, in Victoria. Different varieties are being 
tested for productivity and oil content, and seeds are 
being collected in Queensland for further experiment 
next season. i 
Utility of A large number of different samples of clays are being 
Clays. tested at the Geological Survey Laboratory, Perth, 
, in order to discover which of them are:most suitable for 
industrial purposes. Much valuable assistance and 
advice is being given to persons engaged in the industries 
concerned, 
Worm Nodules An endeavour is being made at an experimental sta- 
in Cattle. tion at Kendall, New South Wales, to discover the 
means by which this disease is transmitted. Valuable 
‘progress has been made, and if the experiments prove 
successful, it may be found ‘possible to control the 
spread of this disease. 
Cattle Tick Investigations are being initiated in Sydney into 
Dips. cattle tick dip formule, and the effect of different dips 
upon the cattle treated. The New South Wales State 
Government is co-operating and bearing half the cost. 
White Ant The New South Wales Department of Agriculture is 
Pest. co-operating with the Institute on a £1 for £1 basis in 
an endeavour to prevent or minimize destruction by 
white ants.
