The Indian, when he examines anything, looks at it very carefully.

One of the fragments was darker on the surface; of this he felt sure, as when he removed them he was careful to keep them as they lay.

Below, the piece had its natural colour, that of dry stone.

He assured himself that the darker shade really proceeded from humidity; it was still moist.

The fragment, therefore, must have been turned over; and that, too, a very short time ago.
