 Five Sovereigns. 



The report should specify as distinctly as possible the kind of 

 trees introduced. The adaptation of the trees for use or orna- 

 ment, and their comparative progress, should be mentioned. 

 Attention is directed to the introduction of any tree as a nurse 

 in young plantations, which by growing rapidly for several 

 years, and attaining maturity when at the height of 20 or 25 

 feet, might realise the advantages and avoid the evils of thick 

 planting.
