“But,” exclaimed the girl, in alarm--“but if they do stay a while, what about us? We simply must have water!”

“True enough. And, inasmuch as we can't drink brine and don't know where there's any other spring, it looks as though we'd either have to make up to these fellows or wade into them, doesn't it? But we'll get water safe enough, never fear. Just now, for the immediate present, I want to get my bearings a little, before going to work.

There may have been some pretense of maintaining the school system, railroads, steamship lines, newspapers and churches, banks and all the rest of that wonderfully complex system we once knew.
