Dartmouth contains many picturesque, highly ornamented old houses, although a large number have been pulled down to make room for modern residences.  Amongst the most interesting of the former is the curious old Butter Row.  Some little way up the harbour, on the west side, is King's Wear, where the Dart Yacht Club have their headquarters.  Near the mouth of the harbour is the Britannia school and training-ship for Royal Naval Cadets.  Here they remain until they have attained a sufficient knowledge of navigation and seamanship to become midshipmen, and make themselves really useful.  Their regular schooling goes on all the time.  Officers in the navy are far more highly educated than they used to be in days of yore, when a knowledge of navigation and seamanship was all that was required.
