agricultural districts, is the most populous town of Eastern Piemont. Vercelli, on the Sesia, and below the confluence of the rivulets descending from Monte Rosa, enjoys natural advantages similar to those of Novara. Casale, the ancient capital of Monferrato, defends one of the principal passages of the Po. But Turin, owing to its favourable position, has become the great emporium of the valley of the Upper Po. Its commerce has grown immensely, since the town no longer enjoys the perilous honour of being the capital of a kingdom, and the places vacated by the court and Government officials have been filled up quickly by immigrants carried thither by the railways. Its libraries, a fine museum, and various learned societies entitle it to rank as one of the intellectual centres of the peninsula, whilst its manufactures of silks and woollens, of paper and other articles, are of great importance. The environs of Turin are delightful. From the hill of the Superga, a few miles to the east of the city, and crowned by a sumptuous church, may be enjoyed one of the finest panoramas of the Italian Alps. The numerous small towns in its vicinity, such as Moncalieri, Chieri, and Carignano, abound in villas and participate in the prosperity of the capital. As to the towns in the valley of the Tanaro, in the south, they form a group apart, and are the natural intermediaries between the valley of the Po and the port of Genoa. Alessandria, a strong fortress of hideous regularity, which has superseded the old fortresses of Tortona and Novi, is the terminus of eight railways, and one of the busiest places of Italy. The neighbouring cities of Asti, famous for its sparkling wines, and Acqui, celebrated from the time of the Romans for its hot springs, are likewise important for their commerce.[71]
