Mr THOMAS BROWN (Calare) . - It seems to me that we are on the eve of bigdevelopments in connexion with motor traction not only for the conveyance of goods on streets and roads, but for station and farm work. In this matter we are far behind the Old World, where motor traction has largely replaced horse traction, and, being a country of magnificent distances, anything that will enable us to get from point to point more quickly and cheaply will be of great advantage to the community. I am afraid that the Minister, in providing against administrative difficulties, may be penalizing the users of pushbicycles and motor bicycles, these vehicles having been largely substituted for horses by shearers and many other workers. According to the honorable member for Wentworth, the riders of push bicycles will be penalized to the extent of1s. 8d. or 2s. a tyre, and of motor cycles to the extent of about9s. on the cheaper tyres. The position might be met by imposing a duty of so much a pound on motor car tyres, and an ad valorem duty, as at present, on bicycle and motor cycle tyres.
