THIXNIXG. 103 



It is recommended, in describing Xos. 20, 2 1, to leave 

 the oaks to mature while a second crop is growing up, 

 and cut them alons^ with the second, and not the first 

 crop. Amongst others, one reason for doing so is that 

 few proprietors like to see a whole plantation swept 

 entirely out of the landscape ; and another is, that to 

 cut old and large trees in the midst of young ones is 

 destructive, and bad forestry : hence, to overcome these 

 difficulties, oak is left, which requires longer time than 

 any other trees to mature, and its branches bear 

 pruning or lightening, which they often require to some 

 extent for the sake of the young and rising crop 

 around them. 



It is of no small convenience to every manager of 

 woods to have in a large book-form a sketch or outline 

 of every plantation under his charge, which should have 

 the contents and measurement of the fences marked 

 upon it, gates shown, also roads, burns, and bridges. 

 This is soon and cheaply done by means of tracing 

 paper, taking the outline from the estate plan or 

 survey, and transferring the same to a book bound for 

 the purpose, of good quality of paper or oil-cloth.
