The plateau is not very wide--half a mile at most--and the second tunnel begins on the eastern side of it.

This new tunnel is at a smaller angle, as it has to pierce the second hill--a mountain this time.

When it comes out on the east side of that, it will tap the real productive belt.

Here it is that our hardwood-trees are finest, and where the greatest mineral deposits are found.

This plateau is of enormous length, and runs north arid south round the great bulk of the central mountain, so that in time, when we put up a circular railway, we can bring, at a merely nominal cost, all sorts of material up or down.
It is on this level that we have built the great factories for war material.
