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.
