The following treatise was compiled from information 

 then in my possession, or within my reach ; and it consti- 

 tuted the basis of the lectures. I had a mixed audience 

 of ladies and gentlemen, tradesmen and young men and 

 maidens still pursuing their studies. The technical 

 information was laid upon the table for consultation by 

 members of the Club or others at their convenience ; the 

 other portions only were read. It is published as a sequel 

 which may be found useful as an introduction to another 

 volume entitled Introduction to the Study of Modern forest 

 Economy, which was lately published in accordance with a 

 resolution formally adopted by promoters of the Exhibi- 

 tion to give their best efforts and endeavours to render 

 the Exhibition a success. 



In Norwegian names I have followed, I consider, the 

 principles of English orthography, but I have not altered 

 the orthography adopted in passages by others which I 

 have so largely quoted.
