Q. It's DURABILITY On this point, The under
signed are unable 10 report anything satisfactory
10 themselves. The duration of timber is eftsc-
It'd by its quality, by climate, and by It's position.
Trees oi tie same speces are moi As uufaole IN
The South as in tic North. The lons>leayed
pine oi Alabama is not SO durable as that OF N.
Carolina. The plank roads OF The North have
been constructed of Hemlock The Abies Coma

plank roads in The State ui New York, on account
SOLELY OF lis abundance AID cheapness.
