As a matter of fact, in accordance with my usual practice, I took long excursions in different directions extending over weeks and even months at a time.

On these occasions I always took with me a kind of nut, which, when eaten, endowed one with remarkable powers of vitality and endurance.

Since my return to civilisation I have heard of the Kola nut, but cannot say whether the substance used by the Australian aboriginal is the same or not.

I remember we generally roasted ours, and ate it as we tramped along.

In the course of my numerous journeys abroad I blazed or marked a great number of trees; my usual mark being an oval, in or underneath which I generally carved the letter "L." I seldom met with hostile natives in this region, but when I did my mysterious bow and arrows generally sufficed to impress them.
