§ Mr. Grovesasked the Minister of Supply whether his attention has been drawn to the new product maycrete, which has been tested and proved to be a very good substitute for timber; and, in view of the possibility of a shortage of timber, whether he will take steps to develop the output of this product?
§ Mr. Harold MacmillanMy attention has been called to this and other possible substitutes for timber for building purposes. It has already been under investigation by the Building Research Station, and I understand that a new specification of the product is to be examined at an early date.
