THE WIRELESS COMPASS.

Referring incidentally to the wireless compass, which has figured in discussions between Auckland shipmasters and the Minister for Marine, an English paper says:—-"One ci the most valuable accessories to v, i-dess of the present day is that of.-the direction finder, or as it has been termed, the wireless compass. By means of this invention it is possible to detect, independent of weather conditions —to which visual means of signalling are subordinate—the direction of one vessel in respect of another. The range of this instrument in the average mercantile equipment extends up to 50 or 60 miles. Another most valuable accessory to wireless telegraphy in summoning assistance to a distressed paratus, which is arranged with one vessel is the submarine signalling apreceiver on the port side and another on the bow of the ship, for direction finding. But as the detection of sound by this moans is Kmitod at present to betAveen 10 and 15 miles it can only be used as an adjunct to the direction finder and as a check upon the readings of the latter."
