the freshness of newly-felled timber. Possibly no better 
evidence is required to show that this is a durable 
wood. 
It is used in ship-building for beams, keelsons, stern- 
posts, engine-bearers, and for other works below the line 
of flotation, for which great strength is required, a weighty 
material in that position not being objectionable in a 
ship’s construction. 
In civil architecture the Tewart is scarcely if at all 
known in this country, although it might be employed 
with advantage for many purposes. It would make good 
piles for piers, and supports in bridges, and be useful in 
the framing of dock gates, as it withstands the action of 
water, and is one of the strongest woods known, whether 
it be tried transversely or otherwise. But it would 
probably be found too heavy for general use in the 
domestic arts.
