In the meantime Genoa is expanding in all directions. Its factories of macaroni, paper, silks and velvets, soap, oil, jewellery, metal-work, pottery, ornamental flowers, and other objects are ever increasing; and _ovrar del Genoes_—Genoese {237} industry—is a marvel now, as it was in the Middle Ages. San Pier d’Arena (Sampierdarena), to the west, has become a veritable manufacturing town. Cornigliano, Rivarolo, Sestri di Ponente with its large ship-yards, Pegli, and Voltri are populous towns, having spinning-mills and foundries. Savona, whose port was {238} filled up by the jealous Genoese, occupies the bottom of a vast bay. It has glass-works and potteries, and is connected by a railway with Turin. Elsewhere on the Riviera di Ponente the towns are crowded closely together. Such is the case with the twin cities of Oneglia and Porto Maurizio, the one built on the beach, the other on a steep hill close by, and known as the “Fountains of Oil,” because of their extensive plantations of olives. At San Remo, however, olives are more plentiful still.[80] On the Riviera di Levante town joins town like pearls in a necklace. Albaro, with its charming mansion, Quarto, whence departed the expedition which took Sicily from the Bourbons, and Nervi, a health resort for persons suffering from pulmonary diseases, constitute a long-stretching suburb of Genoa, extending in the direction of Recco and Camogli, two towns abounding in shipping. The rocky promontory of Porto Fino, thus named after the dolphins which formerly frequented it, imposes an insurmountable obstacle to the further extension of Genoa in this direction. Having traversed the tunnel leading through this promontory, we reach another group of towns, viz. Rapallo, the industrious; Chiavari, a great place of trade; Lavagna, with its famous quarries of grey slates; and Sestri di Levante, a town of fishermen.
