This is another hard wood tree. It does not grow so tall as the gum-trees, being seldom found more than from 40 to 60 feet in height, with a diameter of from 12 to 30 inches. The two species most used for building purposes are the C. torulosa, called the Forest Oak, and the C. paludosa, called the Forest Swamp Oak.

The Forest oak is chiefly used for splitting into shingles, for which purpose it is better adapted than any other timber in Australia. Mr. Atwool had seen some that were so thin that they made a roof which appeared almost as neat as slates.

The weight of a cubic foot is about 42 lbs. The crushing weight of a piece 1 inch high and 1 inch square is about 5500 lbs., and the transverse strength about 790 lbs.
