Barnes Design of Experiments. Statistical Checklist No. 1, issued by the Institute of Terrestrial Ecology, is a seven-page foldin pamphlet written by John Jeffers, now the Director of that Institute. It lists 71 questions which experimenter must ask before a field experiment is laid out, with the object of checking that he is about to do something stupid, unsound, ineffective, wasteful or perhaps merely inefficient. T questions are arranged in nine stages: objectives, defining the population, selecting treatments, shape and size, replication, layout, randomization, recording, and analysis. Finally, Questio 7 1 - "If you are in doubt about the purpose of any of the questions in this checklist, should you no obtain some advice from a statistician ... ?" Indeed you should! There is a well-chosen bibliograp of twelve books, and the pamphlet is available for 30p if a stamped-addressed envelope is sent Publications Officer, I.T.E., 68 Hills Road, Cambridge. In my view, this pamphlet should mo certainly be read by every forest researcher before he sets out his next experiment, and by eve authority about to approve - or disapprove - somebody else's experiment.
