Read it through once

They were such perfectly natural-looking leads that I could hardly keep from “taking them up.” Among the oyster-shells were mixed many fragments of ancient, broken crockery ware. Now how did those masses of oyster-shells get there? I can not determine. Broken crockery and oyster-shells are suggestive of restaurants--but then they could have had no such places away up there on that mountain side in our time, because nobody has lived up there. A restaurant would not pay in such a stony, forbidding, desolate place. And besides, there were no champagne corks among the shells. If there ever was a restaurant there, it must have been in Smyrna's palmy days, when the hills were covered with palaces. I could believe in one restaurant, on those terms; but then how about the three? Did they have restaurants there at three different periods of the world?--because there are two or three feet of solid earth between the oyster leads. Evidently, the restaurant solution will not answer.
