The river is but three miles long before it merges in the estuary, and its banks are sprinkled with villas and villages, the railway station and the admiralty stores occupying the portion nearest to the harbour. From Gravosa the excursion to the plane-trees of Cannosa and to Stagno may be made.
Almonds flower in December, and peas and beans are often gathered at Christmas. At Cannosa the date-palm ripens its fruit, and flowers are always to be seen. The Euphorbia Dendroides grows as high as in Crete, and rosemary bushes are frequently up to the shoulder of a man. In August the Syrian hibiscus is violet-red and the scarlet-red arbutus fruit hangs till Christmas.
