THE FLOWER WALK, REGENT'S PARK.
Regent's Park is the largest of the London parks. and measures no fewer than 472 acres. It was laid out in the reign of George III. by the Prince Regent (afterwards George IV.) - hence its name. There was an earlier park here known as Marylebone Park, but in the time of the Commonwealth this was converted into pasture land. Regent's Park, which contains many fine avenues of trees, is much frequented and the famous Flower Walk is especially popular. The gardeners of the various London parks vie with one another in producing fine floral displays. but the Flower Walk, at the proper season, need fear comparison with no similar garden in all the metropolis.
