Borneo produces several other species of trees, including the Tanjan, Meraha, Mirabeau, Panjan, and the Kampar. These all attain good building sizes, and, judging from the sample logs sent with the Chow, &c., to this country, I am inclined to think they would be found useful and valuable for constructive purposes.

THE MOLAVÉ TREE (Vitex geniculata^[1])

is found in the Philippine Islands, and, judged by the parcel of 6 to 8 loads of selected wood imported here in 1863 or 1864, is of straight growth and moderate dimensions, although, according to Blanco, it is "very often crooked."
