Although no tree will flourifh in a fuperlative

In favourable fituations, although the furface 

 may appear poor and thin, we mould not defpair 

 of rearing fome kinds of tree to perfection ; as in 

 fuch cafes, the under foil is often found of good 

 quality, and able to produce valuable timber.
