The series of experiments started on Salisbury Plain towards the end of 1955 is continuing, but it is as yet too early to assess results. I can say, however, that the effect, if any, has been small. We do not now plan to extend the experiments to hill country in the north of England, as further examination has indicated that the results could not be expected to differ significantly from those obtained on Salisbury Plain.
§ Mr. Grey
Is the Secretary of State aware that, despite the heavy rainfall we have had in certain parts of Durham recently, the reservoir levels are still in a pretty bad way, and that rationing is still very much to the fore? If experiments in rain making are to take place, surely the catchment area of Durham would be a most suitable place?
My information is that the results are unlikely to be any different from those on Salisbury Plain, because the area in which the hon. Gentleman is 406 interested simply is not high enough to make any difference.
§ Mr. P. Williams
Would not my right hon. Friend agree that on the occasion of the Durham Miners' Gala on Saturday of last week there was rather too much rain for the convenience of most people?
As the hon. Gentleman knows, when he raised this point earlier we looked into it very carefully. It is the result of studies made since he raised the matter that has brought us to this conclusion.
