WIRELESS.

EXPERIMENTS IK THE PACIFIC. i By the Tahiti, which, left Wellington '< ou Tuesday, Mr. Charles Maclurcan, of I Sydney, the leading, wireless experi- ■ menter in Australia, left, in company i with an- assistant, Jack Davies, for ' America, in order to undertake a number of experiments on the voyage, indi-' eating the distances at which Australian and New Zealand wireless signals are audible. Air. Maclurcan has already completed .some remarkable coups in wireless communication. Commencing with the i power usually needed to operate his ■ set, he gradually reduced until, after ' considerable experimenting, he was operating his station on about onefortieth part of the power ordinarily needed to light the tail-lamp 01 a motor car, and on this almost negligible force : communicated with a fellow-experimen--1 ter in New Zealand. His teets in connection with the reception of longdistance signals have been almost aa remarkable. Using a special circuit, j he has, during recent weeks, clearly received American signals, using only one valve, and supplying the power necessary to operate the receiver from two small batteries, one of them taken from an ordinary pocket torch, and the other slightly stronger. He will also investigate why American telephony lias been heard in New Zealand but not in Australia up to- now.
