We are tunnelling into the mountains, where are the great deposits of coal.

We run the trucks in and out on the level, and can get perfect ventilation with little cost or labour.

Already we are mining all the coal which we consume within our own confines, and we can, if we wish, within a year export largely.

The great slopes of these tunnels give us the necessary aid of specific gravity, and as we carry an endless water-supply in great tubes that way also, we can do whatever we wish by hydraulic power.

As one by one the European and Asiatic nations began to reduce their war preparations, we took over their disbanded workmen though our agents, so that already we have a productive staff of skilled workmen larger than anywhere else in the world.
