 work. It is chiefly adapted for piles, sleepers, dock work, and shipbuilding, the peculiarity being its resistance to the teredo and white ant, so that copper sheathing in ship­ building is rendered unnecessary. It is classed at Lloyd's (for twelve years) in the third category of timber used for ship­ building purposes. It has recently been employed with success for street-paving purposes in London, and the surveyor of one of the great vestries writes thus regarding the respective qualities of jarrah and deal for that purpose:—"Jarrah is more expensive, and, therefore, a smaller area can be provided at the same cost, but is more uniform in texture and quality, which makes it wear with much more evenness than deal, as deal varies considerably even in the length of a plank, and is liable to wear into holes where soft or sappy. Jarrah will wear much longer, and, taking this into account, it will be found the more economical in the end, besides having the advantages of less scavenging and requiring little or no repairs. This, combined with infrequent renewal, causes considerably less inconvenience to the public."
