message should be sent out during certain hours every
day. 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
