§ 59. Mr. Lindsayasked the Parliamentary Secretary to the Ministry of Food whether he is aware that emergency field ovens can be speedily built at no cost out of bricks and rubble; that many ex-service men now in the Home Guard and the Civil Defence services have experience in their construction; that thousands of meals could be cooked and kept warm by this method in the bombed areas, where there is shortage of equipment; and will he take immediate action to make this known to local authorities?
