They are unacquainted with the process of case-hardening, which, applied to certain parts of our anvils, gives them their usefulness, and an anvil of their soft iron would not do so well as a hard stone.

It is true a small light one might be made, but let any one see how the hammers of their iron bevel over and round in the faces with a little work, and he will perceive that only a wild freak would induce any sensible native smith to make a mass equal to a sledge-hammer, and burden himself with a weight for what can be better performed by a stone.

If people are settled, as on the coast, then they gladly use any mass of cast iron they may find, but never where, as in the interior, they have no certainty of remaining any length of time in one spot.
_5th August, 1866._--We left Miule, and commenced our march towards Lake Nyassa, and slept at the last of the streams that flow to the Loendi.

In Mataka's vicinity, N.E., there is a perfect brush of streams flowing to that river: one forms a lake in its course, and the sources of the Rovuma lie in the same region.

After leaving Mataka's we crossed a good-sized one flowing to Loendi, and, the day after leaving Pezimba's, another going to the Chiringa or Lochiringa, which is a tributary of the Rovuma.
