It is more laborious, but they must live.

If they are kept from passing along the valley, they must climb the mountains.

When the law has thus created a certain amount of obstacles, and when, to overcome them, humanity has diverted a corresponding amount of labor, you are no longer allowed to call for the reform of the law; for, if you point out the _obstacle_, they show you the labor which it brings into play; and if you say this is not labor created but _diverted_, they answer you as does the _Esprit Public_--"The impoverishing only is certain and immediate; as for the enriching, it is more than problematical." This recalls to me a Chinese story, which I will tell you.
There were in China two great cities, Tchin and Tchan.

A magnificent canal connected them.
