Abstract: i 84--86 ,3CHAP.Na Formation of Working Circles 87-Y91 Cuar.V. Determination of the Rotation or These general facts and studies, indispensable in the case of every forest without exception, whether they are detailed or take a broad general view of the forest, whether they head the report or are implied and understood, lead one, so to Say, on to the very threshold of the Organisation Project.Accurately observed and carefully thought out, they guarantee the proper carrying out of the prescriptions which are to regulate the treatment and the exploitation of the forest.Incorrectly noted or carelessly worked out, they make room for all kinds of errors, even of the most grave character, a circumstance which cannot but render defective some portion of the Organisation Project, or be an obstacle to its proper execution.As regards our Course, this Book is perhaps the most important part of it.Once the student has gone, methodically and with a thorough understanding of the facts, through the practical work which it describes, his mind will be able to take in at once the whole subject of Forest Organisation, the various combinations, rules and principles that enter into it becoming perfectly clear to him.We will even go further and say that we do not fear to assert that it is almost impossible to acquire a full and complete knowledge of any forest without possessing both a theoretical and practical knowledge of the operations described in this the Second Book.And this is the reason why we have therein entered into an exhaustive and detailed account of those operations.The Third Book treats of the general features of the Working Plan for high forests.With reference to the subject of a sustained yield in the State Forests, we have established the fact that it is often expedient to subordinate it to the treatment applied and to the requirements of the future, because every year it becomes more and more clear that it ought tomake way for the savings that must be effected in order to enable these forests to yield the most useful products, viz.large timber, the scarcity of which is already felt in France.Moreover, the smethod of Forest Organisation by Area is described here in the same spirit in which it has always been taught at the Forest School ; but, thanks to a more intimate knowledge of facts since acquired, we have been able to separate it from purely theoretical considerations and to place it before the student in an entirely practical light.The study of the organisati on of regular high forests, which is more complete in itself and, all points considered , more natural than of that of copses, is the best beginning to make in the theoretical and This volume which M. Nanquette, whose humble disciple I am, has asked me to publish in my own name, is his handiwork more than mine.As for myself I have only re-written the Course, which i learnt at his feet.He has even been kind enough to revise my manuscript and retouch with his own hand the more important portions.It will hence not be affirming
