Spare the poison

Sir: For the benefit of your readers who are trying to buy our booklet 'In Place of Poisons' on safe garden pesticides (mentioned in 'Spectator's Notebook' on 2 May) through bookshops, may I say that this is free to any- one sending a long stamped addressed en- velope? We have so far given away 20,000 as a contribution to European Conservation Year, and we have a special edition in Braille for blind gardeners. Lawrence D. Hills Director Secretary, Henry Doubleday Re- search Association, Bocking, Braintree, Essex
