ABSTRACT
OAK remains unrotted under water and for this reason is most useful for the sides of ships. The tanning of hides is begun and finished off with its bark, as I shall demonstrate below when I deal with structures built on ice.1 There are also other trees of more than usual hardness, from which rings are turned on a lathe for use on ships' yards, and with whose resin the interior of wine skins and jars should be smeared, so that they do not decompose.
