Passing some cemeteries and public fountains, we came to the outskirts of the city, which consist chiefly of gardens producing olives, oranges, raisins and figs, irrigated by creaking water-wheels worked by donkeys. To one of these the droll contrivances which attracted our notice was affixed. The donkey who went round and round was blinded, and in front of him was a pole, one end of which was fixed to the axle and the other slightly drawn towards his head-gear and there tied; so that, from the spring he always thought somebody was pulling him on. The guide told us that idle fellows would contrive some rude mechanism so that a stick should fall upon the animal’s hind quarters at every round, and so keep him at work whilst they went to sleep under the trees.
