INTRODUCTION. 



treatise appeared originally in the Indian 

 Forester, and it was there explained that it was for 

 the most part a compilation from various German text- 

 books, special use having been made of the article by 

 A. Ritter von Guttenberg in Lorey's "Handbook of 

 Forestry " published in 1887. In the first instance 

 the German originals were closely followed and special 

 regard was paid to diameter measurements, which give 

 more nearly the actual contents of logs and trees, and 

 which are used on the continent of Europe by buyers 

 and sellers of timber ; but, since in England and India 

 the contents of round timber are always calculated on 

 the assumption that the sectional area of a log is deduced 

 from the square of the quarter-girth, it has been thought 

 advisable in the present edition to have regard to the 

 established custom, and thus render this treatise of 

 more practical value to the English and Indian student.
