HinTs RESPECTING SOME USEFUL KINDS OF FOREST 
TREES, NOT GENERALLY KNOWN IN THIS COUNTRY.

Communicated by a correspondent in Manchester. 
1. Luz iron oak, which thrives three times as 
fast as the common Englifh oak, and is equally 
beautiful. This oak is sold by Mr Lucombe of Exe- 
ter, and is the oak on which he grafts the Lucombe 
oak. 
2. Populus Greca or Athenian poplar. . This pop- 
lar is of the quickest growth of any tree we know, 
especially upon a gravelly soil, and therefore the 
most profitable in the neighbourhood of Manchester, 
for the purpose of making boxes, where duration is 
“not necefsary. And it is the most ornamental deci- 
duous tree we are pofsefed of, because it is the first 
in leaf, and the last in going out of leaf, and its 
leaves never are insected nor blighted; its bark is of 
the most beautiful silver colour. It is propagated by 
layers and suckers. 
3-Betuta, fol. rhombeo, ovatis, acuminatis, duplicoto, 
serratis: This Ilaminformed isthe most useful and pro- 
fitable tree in North America; it is calied the black 
_birch. It thrives equally well in this climate, and 
is a most desirable tree in plantations of ornament and 
fhade, being one of the first in leaf in the spring, and 
has a beautiful bark.
