If, therefore, a kind of wood canbe found which offers the same conditions of durability as iron in seawater, while it offers the advantage of being three times as strong underequal weight, subject, of conrse, to the conditions above stated, nothingcould justify the use of the latter in preference to the former, since therecan belittle doubt but that the wooden gate would be cheaper than theiron one. Upon these works the kind of wood invariably used for thispurpose is Greenheart, which it is found is not destroyed readily by any ofthe various forms of decomposition which usually render wood useless, asan agent of resistance, and which is not readily attacked by those
