It is a handsome mausoleum faced with blue and white glazed tiles, standing under the shade of some magnificent silver poplars.
Near the town was the famous fountain of Sauros, inclosed by fruit-bearing poplars; and not far from this was another spring, overhung by an evergreen plane tree which in popular belief marked the scene of the amours of Zeus and Europa.
The species most liable to be struck are oaks, poplars and pear trees; beech trees are exceptionally safe.
The poplars are almost entirely confined to the north temperate zone, but a few approach or even pass its northern limit, and they are widely distributed within that area; they show, like the willows, a partiality for moist ground and often line the river-sides in otherwise treeless districts.
