"A species of gum-tree, the bark of which on the trunk is that of the ironbark of Port Jackson."
1830. R. Dawson, `Present State of Australia,' p. 183:
"It was made out of a piece of bark from a tree called ironbark (nearly as hard when dry as an English elm-board)."
1865. Rev. J. E. Tenison-Woods, `History of the Discovery and Exploration of Australia,' vol. ii. p. 45:
"But this gradually changed to an ironbark (<i>Eucalyptus resinifera</i>) and cypress-pine forest."
187. T. Laslett, `Timber and Timber Trees', p. 199:
"The Ironbark-tree (<i>Eucalyptus resinifera</i>) is . . . widely spread over a large part of Australia. . . . A lofty forest tree of moderate circumference. . . . It is believed to have been named as above by some of the earliest Australian settlers on account of the extreme hardness of its bark; but it might with equal reason have been called ironwood. The wood is of a deep red colour, very hard, heavy, strong, extremely rigid, and rather difficult to work . . . used extensively in shipbuilding and engineering works in Australia; and in this country (England) it is employed in the mercantile navy for beams, keelsons, and . . . below the line of flotation."
1883. G. W. Rusden, `History of Australia,' vol. i. p. 77:
"The ironbark (<i>Eucalyptus sideroxylon</i>) became from its durability a synonym for toughness."
1890. Rolf Boldrewood, `Miner's Right,' c. xxvii. p. 248:
