Not illustrated. 1895 edition. Excerpt: ...due to their texture, but to the fact that they contain poison or pungent oils which are distasteful to these creatures. Of these greenheart, sneezewood, and jarrah are the best, teak and oak being also fairly good. In many situations, well-creosoted Baltic red-wood timber, containing at least 10 lbs. to 12 lbs. of creosote per cubic foot, will be found to answer fairly well.1 A few years ago (1889), I happened to visit Holyhead during the time that some of the piles of the old harbour timber jetties were being renewed. Those which were being taken out were of creosoted timber, and they had been in the jetty since the year 1860, or for about twenty-nine years. Some of them were certainly very badly eaten, apparently entirely by Limnorioe, but the timber which remained was perfectly sound. As the cost of creosoted timber does not usually much exceed one-third that of greenheart, it is well worth while to consider whether, in positions where the worm is not very active, it may not with advantage be used. This point, like many others, resolves itself into a question of expediency. In order to arrive at a correct decision, it is necessary that reliable data should be forthcoming respecting the site where it is intended to use the timber; otherwise the estimated life of the timber may be very wide of the mark. 1 It is customary with French engineers, and some others, to use as much as 18 lbs. or 19 lbs. of creosote per cubic foot of timber, when such is to be used in seaworks. So far as I am aware, the only satisfactory information on this subject is that derived from a careful examination of various kinds of timber which may have been in the sea for some considerable time at the site of the proposed works. It cannot be argued that, because...
