GOOD EARTH Thooughts on Feeding. By Lionel J. Picton, OBE (Pp. 265; illustrated. 12s. 6d.) London: Faber and Faber. In much of this book the author stresses the value of foods grown with the aid of natural manures and compost. The loss of nutrients in the urine and faeces of our great urban populations is undoubtedly a major disturbance of the cycle of Nature. lt is not easy to see how it can be prevented in the near future, yet any biologist must think that, like the impoverishment of our mineral and timber resources, it is one of the limiting factors of Western civilization and must sooner or later be ended. Some of the ideas which Dr. Picton advances and which are associated particularly with the names of Sir Albert Howard and Lady Eve Balfour are, to say the least, highly controversial. It certainly would not be true to say of the animal creation that insects and fungi do not cause disease, or that protection by means of sprays, powders, and so on is unscientific and unsound. Surely no malariologistwould subscribe to such a doctrine, and malaria is one of the most serious diseases of mankind. It is therefore difficult to believe that these" basic principles" can be true of disease in plants or that the abolition of chemical fertilizers and parasiticides would promote animal and plant health. The more widely supported view is that only a judicious combination ofhumus and chemicals can attain this end. In any event, a civilization whose manure is wholly organic has been a stark impossibility for many years. Evidence for these statements is given in many publications, such as David Lilienthal's book, TVA, on the Tennessee Valley schemne, or Donald Hopkins's Chemicals, Humnus and the Soil. Nevertheless, we entirely agree with much else that Dr. Picton says. We of the younger generation sometimes forget the immense advance in knowledge of nutrition made during the professional life of men like Dr. Picton. It needed the Boer War to reveal the deterioration in national vigour brought about by a diet of tea, white bread, and jam, and the 1914-18 war to start the first large-scale measures to redress it. The importance of the protective foods, the vitamins, and the trace elements-discussed by Dr. Picton with a wealthof historical insta-tce and personal experience-is still too little known to the general public. Coal and agriculture are to be the two main factors in our readjustment to the post-war world, and it is therefore fitting that a group of doctors practising between the coalfie! ds of South Lancashire and the rich grass-lands of Cheshire should have signed the medical testament on which Dr. Picton's book is to some extent a commen-tary. We wish them success in their proselytizing, advisingthem only to be SLure to basetheir preaching on sound evidence. LJ WITTIS.
