Hurrying back, we continued our voyage.  We passed the mouth of the deep denied Inverfarigaig, with the black rock resembling a ruin above it, and further on Urquhart Castle, built on a detached rock overlooking the loch, the most conspicuous object being a strong square keep, surmounted by four turrets.  The banks of the loch now appeared far more cultivated than at the other end.  Sailing through little Loch Dochfour, we again entered the canal, which runs down into Loch Beauly; while the river Ness, which we had on our right side, falls into the Moray Firth, close to Inverness, which stands on a plain about a mile off.
