THE private bill promoted by the Metropolitan Water Board, which may involve the destruction of Holly Lodge Farm (see NATURE of February 2, p. 177), was read a second time in the House of Commons on February 18. Sir A. Boyd-Carpenter moved that an instruction be given to the committee which is to consider the bill to leave out works on this site, on account of the unique value of the farm as a research centre. After discussion, Sir Hilton Young, Minister of Health, pointed out that he had consulted the Minister of Agriculture on the matter and it was agreed that the appropriate means of dealing with the question was to refer it to a committee of the House. Sir A. Boyd-Carpenter's motion was then by leave withdrawn. In a letter in The Times of February 15, Sir William Prescott, chairman of the Metropolitan Water Board, stated that the “site for the proposed reservoir at Walton has been selected after the most exhaustive examination of other available lands”. It is not stated whether the expert opinion available to the Ministry of Agriculture or to the Geological Survey has been sought, but it is much to be hoped that such scientific advice may be consulted before the matter comes under discussion in committee of the House of Commons.
