HAMPSTEAD HEATH : THE FLAGSTAFF, WITH APPROACH TO "JACK STRAW'S CASTLE"
That part of ever-attractive Hampstead Heath, marked by the Flagstaff, is one of its highest and breeziest points. Our view embraces part of the pond dear to dogs and horses and to children, and in winter to skaters of all ages. The road in the foreground comes up from High Street, Hampstead; and at the point where it diverges into the Spaniard's Road in one direction, and Heath End Hill in another, is "Jack Straw's Castle" (just visible at the extreme right of the picture), an old-fashioned inn which has been visited by many a famous literary man and artist of a past age. On the right will be seen one of the bird-catchers who carry on their operations in this neighbourhood. From the Flagstaff, as we show in another view (page 49), there is an exceptionally extensive prospect westwards.
