The ball now is on its way to the Weapons Research Establishment at Salisbury, South Australia. Boulia station owner Mr J. McClure found the 44 in diameter charred ball on his property yesterday.

Boulia is 130 miles north of Broken Hill. The experts who examined the ball today think it could be from a space vehicle. But they could not say what purpose it would have serves. It is an alloy, possibly of beryllium, titanium and magnesium. The ball, is light (12lbs) and is very strong, it has been machined into shape. A device resembling a sickle has been painted on the burned off. The ball has a dent on the surface and a fine weld around the circumference. But the weld was not a join the experts said.

The director of the Broken Hill division of the University of New South Wales Mr, T. K. Hogan) said the unusual submerged arc weld around the surface of the sphere was "a most beautifully executed job." He refuted suggestions that the ball could be a tank or cistern float. "It is an alloy which is hard to scratch and probably has a high melting point," he said.

"Its appearance suggests that it could have been covered with heat shield which protected it from the heat which melted the lugs.
