asked the Minister of Fuel and Power whether it is his intention now, or at some future date, to put into operation the scheme prepared and submitted by Mr. F. O. Harber, borough electrical engineer at Bangor, for the production of electrical power by means of harnessing the waters of the Menai Straits, details of which have been made available to him.

The merits of the scheme cannot be determined without a detailed survey and the construction of a tidal model. Capacity for the construction of such models is limited and is being reserved for the tidal model for the Severn Barrage Scheme. For the present, therefore, I regret that we cannot proceed with the tests required.
