Mr. Arthur Davis, of the firm of Rubin and Davis, pearl buyers, Broome, was just returning from Melbourne after undergoing a serious operation. He was not fairly recovered from the effects of this, but being under the necessity of visiting his buying agent at Shark Bay, was practically forced to travel by the Koombana. He would otherwise have waited a fortnight. Mr. Davis was highly esteemed by all who knew him.
