After a brief notice of the islands of Brazza and Solta--a notice, however, sufficient for all useful purposes--we pass on to the picturesque neighbourhood of the falls of the Kerka. Sir Gardner speaks of the delay to which the passage by boat from Sebenico to Scardona is subject, but does not exactly complain of it. In fact, we can easily understand that, for the sake of the passenger, it is expedient that some authoritative note should be taken of his departure under charge of the particular boatmen who undertake his convoy. We never did ascend to Kerka, but from what we have seen of the class of men under whose guidance the expedition has to be performed, we are disposed to vote the caution of the police to be anything but superfluous. Every now and then one hears dreadful stories of the atrocities of boatmen in convenient parts of the Mediterranean; and there is good reason to be thankful that the Austrians think it worth while to be so careful of strangers. The people about Sebenico, through whose lands the course of the lake leads, are spoken of as not paying much attention to agriculture or to their fisheries; but it seems that they are sedulously bent on raising grapes, and neglect no patch of ground at all likely to be available for this purpose. The lake of Scardona is considerably larger than that of Sebenico. On the shore here the Romans had a settlement, of which scarcely any remains are perceptible. They are, however, remarkable as affording a manifest proof of the rise of the level of the lake, for some of them are under water. Scardona, we are told, does not occupy the site of the old Scardon, which was a place of considerable importance under the empire. Some have even imagined that the old city stood on the opposite bank of the river. The town at present is small, but well furnished for the convenience of strangers. It boasts an inn, at which Sir Gardner put up for one night. He then proceeded to the falls, which are distant from the inn a three-quarters-of-an-hour journey. As he intended to ascend the river above the falls, he had to send to the monks of Vissovaz to ask for a boat, and they readily complied with his request. The falls do not seem to have been full on the occasion of this visit--but, when full, the effect must be striking. They are divided into two parts, and their picturesque effect is greatly enhanced by the surrounding scenery.
