“We saw rude piles of stones standing near the roadside, at intervals, and recognized the custom of marking boundaries which obtained in Jacob's time. There were no walls, no fences, no hedges—nothing to secure a man's possessions but these random heaps of stones. The Israelites held them sacred in the old patriarchal times, and these other Arabs, their lineal descendants, do so likewise. An American, of ordinary intelligence, would soon widely extend his property, at an outlay of mere manual labor, performed at night, under so loose a system of fencing as this.”
― Mark Twain, The Innocents Abroad
