HC Deb 06 May 1909 vol 4 c1206
Colonel LOCKWOOD

asked the First Lord of the Admiralty whether individuals of foreign nations are allowed to take soundings within the limits off Holyhead; and, if not, what means are taken to prevent them so doing?

The FIRST LORD of the ADMIRALTY (Mr. McKenna)

The taking of soundings when approaching land is not prohibited; it is an essential navigational precaution.
