with abundance of the cypress-pine (Callitris arenaria) a wood much prized for ornamental work.

The appearance along the shores of the Pandanus or screw-pine, which now attains its southern limits, introduces a kind of intertropical appearance to the vegetation.

Among the other plants are three, which merit notice from their efficacy in binding down the drift sand with their long trailing stems, an office performed in Britain by the bent grass (Arundo arenaria) here represented by another grass, Ischaemum rottboellioide: the others are a handsome pink-flowered convolvulus (Ipomoea maritima) one stem of which measured 15 yards in length, and Hibbertia volubilis, a plant with large yellow blossoms.
PORPOISES AT MORETON BAY.
Among the marine animals of Moreton Bay are two cetacea of great interest.

The first of these is the Australian dugong (Halicore australis), which is the object of a regular fishery (on a small scale however) on account of its valuable oil.

It frequents the Brisbane river and the mudflats of the harbour, and is harpooned by the natives, who know it under the name of Yung-un.
