In cases of extreme thirst, where the throat is dry and parched, or life at all in danger, the toil of digging for the roots would be well repaid by the relief afforded. I have myself, in such cases, found that though I could by no means satiate my thirst, I could always succeed in keeping my mouth cool and moist, and so far in rendering myself equal to exertions I could not otherwise have made. Indeed, I hold it impossible that a person, acquainted with this means of procuring water, and in a district where the gum-scrub grew, could ever perish from thirst in any moderate lapse of time, if he had with him food to eat, and was not physically incapable of exertion. Under such circumstances, the moisture he would be able to procure from the roots, would, I think, be quite sufficient to enable him to eat his food, and to sustain his strength for a considerable time, under such short stages as would gradually conduct him free from his embarrassments. In addition to the value of the gum-scrub to the native, as a source from whence to obtain his supply of water, it is equally important to him as affording an article of food, when his other resources have failed. To procure this, the lateral roots are still made use of, but the smaller ones generally are selected, such as vary in diameter from an inch downwards. The roots being dug up, the bark is peeled off and roasted crisp in hot ashes; it is then pounded between two stones, and has a pleasant farinaceous taste, strongly resembling that of malt. I have often seen the natives eating this, and have frequently eaten it myself in small quantities. How far it alone would support life, or sustain a man in strength, I have of course no means of forming an opinion; but it is, probably, only resorted to when other food is scarce. Several of the roots of other shrubs are also used for food, and some of them are mucilaginous and very palatable.
