The next day the signals thus dispatched from Cornwall were distinctly received at Glace Bay and at the pre-arranged times, thus indisputably proving that the Atlantic could be bridged by wireless, and that the transatlantic expansion of the development was entirely dependent upon the suitability of the apparatus. In the meantime the wireless equipment of mer- cantile vessels, owing to the success of the installation upon the German liner, progressed rapidly. The first British liner to be provided with this facility was the s.s. Lake Champlain, of the Beaver Line, in May, 1901. Other shipping companies speedily emulated the example, and the Cunard liner Campania was the first to be fitted with wireless capable of receiving messages up to 1,000 miles. These steamships proved invaluable in connection with the experiments at Poldhu, and recalled the days, some five years before, when the tug was requisitioned to extend wireless across the Solent. Slowly but surely the distance at which the invisible waves could be trapped and de- ciphered into messages increased until, in February, 1902, the liner Philadelphia remained in communi- cation with Cornwall over 1,551 miles, while she received the " S’s” up to 2,099 miles. These achievements were distinctly encouraging. So much so, that Mr. Marconi began the construction of a high-powered station at Cape Breton to com- plete further tests, which work was appreciably facilitated by the liberal grant of £16,000 from the Canadian Government. While this station was under erection, experiments were continued with the cruiser
