“Oh, not at all. We shall build a comfortable shelter to-morrow, and we’ll be glad to have you for our guest. As you see, we’re digging a well, and we’ll have good sweet water by morning.”

“That is very wise. I should have dug one myself if I had had any sort of implement to dig with, but I have none.”

“And so you’ve had to get on with the rather repulsive water from the spring down there?”

“Yes, and no. I have used that water, but I distil it first. You see, in my peculiar business, I must wander in all sorts of places, wholesome and unwholesome, and it is often impossible to find good water to drink. So for years past I have always carried a little distilling apparatus of my own devising with me. It is very small and very light, and, of course, when I have to depend upon it for a water supply, I must use water very sparingly. I think I must bid you good evening now, as I did not sleep at all last night. I will see you in the morning.”

“We’ll expect you to join us at breakfast,” said Larry.

“It will give me great pleasure to do so. Good night.”

With that he nimbly tripped away, leaving the boys to wonder who and what he was, and especially what the “business” was that he had not yet finished at Quasi. Cal interrupted the chatter presently, saying:

“We’ve annexed a riddle, and you’re wasting time trying to guess it out. Nobody ever did guess the answer to a riddle. Let’s get to work and finish the well.”

The boys set to work, of course, but they did not cease to speculate concerning the stranger. Even after the well was finished and when they should all have been asleep they could not drive the subject from their minds.
