§ Mr. D. Marshallasked the Postmaster-General what progress is being made with his proposal that the public should use 30W codes in order to facilitate the mechanisation of letter sorting.
§ Mr. MarplesGood progress is being made. A survey of public opinion aimed at finding out how far people would be prepared to use postal codes is now well advanced. First indications are that the response will be favourable. The Applied Psychology Research Unit of the Medical Research Council at Cambridge is helping us to find the best kind of code. Meantime, we are pressing on with the design of machinery for coding and automatic sorting of letters.
