Towards the Hart river the veldt is level, with several isolated ranges of hills. At the west end of one there is a conical hill, formed entirely of limestone and fossil bones, so blended together that it is impossible to separate them--teeth, jawbones, and other parts of animals, large and small, are found. The surrounding hills are of sandstone formation, with large boulders of a bluish colour that overlap them. I think there can be no doubt as to the origin of the formation of this chalk hill, viz. by the action of the water when submerged in the ocean. The bones and chalk, the latter being held in solution, would be brought together and deposited in comparative still water by the eddy formed by the current rounding the end of the adjacent hill, but from whence the immense mass of bones comes is a question not so easily solved; being of the same specific gravity they may have been deposited in the eddy. I visited the hill several times in passing, and spent many hours on its side and summit with my hammer breaking off pieces to ascertain if any human remains could be found, but not being an anatomist my labour was partly in vain. Of every piece of rock I detached from the hill nearly one-half was composed of bones, all perfectly white, the same as the limestone, and exceedingly hard. In many other localities I have found masses of bones imbedded in limestone; the former have been white, the latter of a dark greyish colour, forming extensive caves, from which beautiful springs of delicious water flow, showing that animal life existed prior to the general configuration of the present earth's surface.
