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, sternposts, 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.
