The transmitting aerial at the New Brunswick station is of the inverted L type, consist-ing of 32 wires with a flat top approximately 5,000 feet in length. It is supported on tworows of steel tubular masts (6 masts in each row), which are approximately 400 feet inheight.

The transmitter at Carnarvon, Wales is substantially a duplicate of the New Bruns-wick transmitter, the source of power being a 300 K. W., ISO cycle motor generator MARCONI TRANSOCEANIC RADIO TELEGRAPHY. 295 with step-up transformers, oil condensers, etc. Of late, a 150 K. W. timed spark discharger,excited by 5,000 volts continuous current, has been employed as well, and with which par-ticularly successful results have been obtained. Operated usually at the wave length of10,000 meters, daylight communication has been established with the U. S. A., the strengthof signals being equal to that obtained from other foreign stations of much greater power.(For a more detailed explanation of timed spark discharger sets see paragraph 219.) Some idea of the construction of the Marconi high power stations may be ob-tained from the following description: The power house of the transmitting section of the Wales Transoceanic station at Car-narvon, Wales
