The dots and lines and pothooks clearly belong to a system of picture-writing.

Can we make out their meaning at all?
Once in a way, perhaps.

Note these marks looking like two different kinds of throwing-club; at any rate, there are Australian weapons not unlike them.

To the left of them are a lot of dots in what look like patterns, amongst which we get twice over the scheme of one dot in the centre of a circle of others.

Then, farther still to the left, comes the painted figure of a bison; or, to be more accurate, the front half is painted, the back being a piece of protruding rock that gives the effect of low relief.
