Sir,

Hongkong, 21st. May, 1912.

Wireless Telegraphic Station.
Referring to our Senior's letter of 28th. February we
have pleasure in informing you that we have now received full particulars of the proposed Station, from our Principals, Messrs. Marconi's Wireless Telegraph Company, Limited, copies of which, together with drawings we enclose herewith.
Messrs. Marconi in their letter to us, reply as follows
to the several points which we raised and which we think are worthy of consideration. The 30 Kilowatt Station proposed, al- -though it can safely be guaranteed for the day range of 850
Nautical Miles specified, when working across open water, cannot
be relied upon for regular day and night working over this dis- -tance when land of a highly mountainous nature lies in the line
of communication. Should the Station be required to work in con-
-nection with a similar station in Shanghai, communication would
be required across some 660 Nautical Miles practically entirely over land, including some considerable elevations. Although there is every probability that such communication could often be established particularly during the night hours, they do not
think it advisable to guarantee regular working with that point.
According to more recent practices they have
included with the main 30 Kilowatt Installation a Subsidiary 3
Kilowatt Installation, which would be employed when working over
comparatively short distances on the regular wave length used in
Ship Communication.
With regard to the question of the severe climatic
conditions obtaining at Hongkong at certain times of the year,
Messre. Marconi advise us that the Patent Sectional Steel Masts
which are provided for in the Tender, are designed with an ample margin of safety to meet such contingencies, and have been erected under the most varying conditions in all parts of the
World,
