When going down the Tigris and Euphrates rivers many years ago with a party of English travelers I found myself under the direction of an old Arab guide whom we hired up at Baghdad, and I have often thought how that guide resembled our barbers in certain mental characteristics. He thought that it was not only his duty to guide us down those rivers, and do what he was paid for doing, but to entertain us with stories curious and weird, ancient and modern strange, and familiar. Many of them I have forgotten, and I am glad I have, but there is one I shall never forget.
