the handle. It forms a natural sealing-wax, and for this purpose 
is used by the settlers in the interior. It would certainly serve as 
a constituent of black sealing-wax; alone, it is too soft for long 
keeping. 
It is usually received in small rounded lumps, weathered on 
the outside, and possessing a pleasant, empyreumatic odour. The 
lumps appear of a dark reddish-brown colour, and if the weather 
be not warm they fly with the slightest touch of the pestle, and 
are easily powdered. The resin softens even with the warmth of 
the hand, and if kept in a bottle the heat of an average summer 
day is sufficient to fuse pieces presenting fresh fractures. It has 
a bright, almost black fracture, showing reddish-brown at the 
edges. It presents some resemblance to Guaiacum (especially 
when this resin comes to the market in small lumps), but it is not 
so green in colour as the latter.

“‘Cheesewood.”’ (For other names, see ‘‘ Timbers.”’) 
This tree yields a gum-resin which easily softens in the heat 
of the sun, but which only appears to be obtained from wounded 
trees. It is viscid, possesses a powerful, and to my mind a 
delicious odour of a turpentiny character, which somewhat 
resembles that of oil of cubebs, but the odour is quite per se. The 
author has been informed that a gentleman in the Illawarra district 
applied this “gum” to a wound of a dog, ‘on account of its 
aromatic smell,” when the wound healed “ with amazing quickness 
in a few days.” 
See pages 219 and 220 for an account of some gums from 
species of Prttosporum.
