There are several valuable kinds of wood in this colony, which do not exist in South Australia or New South Wales. We may mention the sandalwood, which now finds a market in Ceylon, where it fetches about 22 pounds per ton; but if it were sent direct to China, (its ultimate destination,) it would obtain probably 35 pounds per ton. Sandal-wood is burnt in large quantities in China, as a kind of incense. There is another highly-fragrant wood peculiar to this colony, called by the settlers raspberry jam, from its resembling that sweet-meat in its scent. A small quantity sent to Tonbridge-Wells, was worked up into boxes, and highly approved of by the cabinet-makers, who gave it the name of violet wood. One of the most beautiful trees in the colony is called the peppermint-tree; its leaves, which are very abundant, resemble those of the willow, and, on being rubbed, smell strongly of peppermint. It bears a small yellow flower. These is much reason to believe that this is of the same species as the tree which yields the valuable Cajeput oil, and it is highly desirable that an endeavour should be made to distil this oil from the leaves. Many of the vegetable productions of Western Australia appear to correspond with those of Java and others of the Eastern Islands, modified by the difference of climate. The timber adapted to ship-building purposes, extends in vast quantities down the line of coast, and is of three kinds, all varieties of the eucalyptus. The tooart in the districts of Bunbury and the Vasse, and the blue-gum which abounds at Augusta and Nornalup, are woods of large size, and remarkably hard and close-grained in texture. It is well adapted for keel-pieces, stern-posts, capstan-heads, and heavy beams: and its fibres are so closely matted and interwoven together, that it is scarcely possible to split it. It grows in lengths of from 30 to 60 feet, and measures from 15 to 30 inches in diameter. But the wood most highly prized and most easily attainable is the Jarra, which grows upon the entire range of the Darling Hills, distant from sixteen to twenty miles from the coast, and extends over a country averaging at least twenty miles in breadth. It was for a long time erroneously called mahogany by the settlers, as it takes an excellent polish, and is extremely useful for cabinet purposes. A small quantity recently sent to England for the purpose of being worked up with furniture, has been thus reported upon: --
