WIRELESS STATIONS.

WHEN CONSTRUCTION WILL COMMENCE.

Material for the wireless telegraphic stations in New Zealand has been ordered by the contractors to the Government (says the “New Zealand Times.”) and should come to hand in a couple of months. The Australian Wireless, Ltd., which obtained the New Zealand contract, has ten months in which to complete the Doubtless Bay high-power station, and will probably havetheother high-power station at Bluff finished about that time also. The four lowpower stations should be ready simultaneously, so that in ten months the Post Office will be able to accept commercial messages. So far, there has been no revenue from wireless, as the plant at the Wellington G.P.O. is regarded purely as an experimental one. Its effective range is about 600 miles, but curiously enough, when the other instrument is on a snip approaching Welington from east or west, communication is almost impossible as soon as the vessel gets within about 200 miles of land.- The explanation is that intervening mountains break the waves* aiid that they do reach their power again at sea level for several hundred miles. It is for this reason that the department has to acquire a wireless station site on the lofty Tinakori lims, not far from Northland.
