PREFACE 



BY way of preface to this translation of Professor Schwap- 

 pach's Forstyvissenschaft, a. word or two of explanation seems 

 necessary. 



The author has been careful to avoid anything which is 

 only locally applicable, so that the matter which the book 

 contains is quite as suitable for British as for German readers. 

 Forest conditions change within Germany as they do within 

 our own country, but the principles the natural laws 

 governing forest practice are unalterable, being the same at 

 all times and in all places. This being so, the English 

 adaptation of a book dealing concisely with these principles 

 and emanating from such an able author must surely be 

 useful. Forestry in its economic aspect is the subject treated, 

 and anything peculiar to Germany or any other country is 

 specifically mentioned. Some portions of the original, par- 

 ticularly Forest History and Valuation, have been abridged ; 

 while those bearing on Sowing and Planting, Insects, Fungi, 

 and Forest Management have been somewhat extended. 

 The illustrations also have been added. 



I must, no doubt, hold myself responsible for the book in 

 the form in which it is now given to English readers, but I 

 desire to acknowledge my indebtedness to Dr. Eric A. Nobbs, 

 of the Department of Agriculture, Cape of Good Hope, 

 who began the translation. Also to Dr. William Somerville, 

 of the Board of Agriculture and Fisheries, my thanks are 

 due for the helpful interest he has taken in the work.
