Bulletins - 3000 - 3999

The systematic investigations of the potential of the Ord area for irrigated farming began during the Second World War when the possibilities of damming the river were first examined, initial soil survey was carried out, and agricultural experiments started. The Kimberley Research Station was established on its present site in 1945. A year later the State and Commonwealth Governments agreed to finance and operate the Station jointly, with CSIRO and the Western Australian Department of Agriculture being responsible for research.

The construction of the main dam designed to store 5,675 million m" ( 4.6 million acre feet) was completed in …

Leaflet No 1001 - Aerial Baiting For The Control Of The Little Plague Grasshopper (Austroicetes Cruciata Sauss), C. F. Jenkins

Bulletins 1 - 2999

Aeroplanes have been tested for grasshopper control in many parts of the world during the last decade but the insecticides used have been in either dust or spray form.

The aerial distribution of bran bait is quite a recent development in overseas countries and was tried for the first time in Western Australia during the spring of 1949.

Leaflet No 1002 - Swine Paratyphoid (Salmonellosis Necrotic Enteritis), C R. Toop

Bulletins 1 - 2999

Paratyphoid is an infectious disease of pigs which is likely to make it appearance wherever pig raising is practised.

It may occur in an acute septicaemic form which is often rapidly fatal and accompanied by serious mortality and in a sub-acute or chronic form known as necrotic enteritis which is characterised by unthriftiness and scouring. The out breaks occurring in Western Australia are principally of the acute type and they are usually associated with the introduction of pigs from saleyards.
