dangerous to any hostile squadron on the Italian coast, as its cruisers would cut off all transports of coal, provisions, &c. &c.,--in a word, render the communication of the hostile squadron with the Mediterranean very difficult.... Lissa is the keystone of the Adriatic. This island, the importance of which in former times was never denied, commands the straits which lead from the southern to the northern half of the Adriatic.... The naval force at Lissa ought to be a local one, consisting of light fast gun-boats to cruise in the narrow waters, to which might be added some plated ships to keep open communications, on the one hand, between Lissa and the mainland, and on the other hand acting with the gun-boats to bar the passage to hostile vessels.' The publication of the article from which the above is extracted in the 'Oesterreichische Militar Zeitschrift,' proves sufficiently that the Austrian government is aware of the necessity which exists for taking precautionary measures; and the lesson which they learnt in 1859 ought to have induced them to adopt a more energetic policy in their military and naval affairs. The defences of Sebenico consist of three small forts: St. Nicholas, containing seventeen mounted guns, is at the entrance of the bay, while San Giovanni and Santa Anna, situated on rising ground, command the town, harbour, and land approaches. The precise number of guns which they contain, I was unable to learn. The very meagre character of the information which I am in a position to impart on these subjects requires, I am aware, some apology. The difficulty of obtaining it during the short stay of a steamer must be my excuse. May it be accepted!
