Senator SENIOR (South Australia) . - I am glad the Minister has given that information. When the chlorine is removed from salt sodium remains, and from sodium, we obtain soda ash, carbonate of soda, caustic soda, and bi-carbonate of soda. The major portion of these commodities can be produced in Australia, including ultramarine blue. A short time ago I visited Longwood, in South Australia, where china clay or kaolin is found, and from which I saw a very good sample - one of the best I have ever handled - of ultramarine blue produced. This product was manufactured without the assistance of any extensive plant; but it was of a very satisfactory quality, and proved conclusively what can be done in Australia. We should by all means at our disposal encourage the production of raw materials required in local manufactures, and as these products are used in connexion with the manufacture of laundry blue the industry should receive every encouragement. For these reasons I support the proposed duties.
