But our leave is over, and although it would be pleasant to travel in imaginative company up the beautiful Hudson, and visit one of the wonders of the world—Niagara, to-day a mere holiday excursion from New York—we must away, merely briefly noting before we go another of the wonders of the world, a triumph of engineering skill: the great Brooklyn bridge, which connects that city with New York. Its span is about three-quarters of a mile; large ships can pass under it, while vehicles and pedestrians cross in mid-air over their mast tops, between two great cities, making them one. Brooklyn is a great place for the residences of well-to-do New Yorkers, and the view from its “Heights”—an elevation covered with villas and mansions—is grand and extensive. Apart from this, Brooklyn is a considerable city, with numerous churches and chapels, public buildings, and places of amusement. [Illustration: FERRY-BOAT, NEW YORK HARBOUR.] Halifax is the northernmost depôt of the whole West India and North American Station, and is often a great rendezvous of the Royal Navy. It is situated on a peninsula on the south-east coast of Nova Scotia, of which it is the capital. Its situation is very picturesque. The town stands on the declivity of a hill about 250 feet high, rising from one of the finest harbours in the world. The city front is lined with handsome wharfs, while merchants’ houses, dwellings, and public edifices arrange themselves on tiers, stretching along and up the sides of the hill. It has fine wide streets; the principal one, which runs round the edge of the harbour, is capitally paved. The harbour opposite the town, where ships usually anchor, is rather more than a mile wide, and after narrowing to a quarter of a mile above the upper end of the town, expands into Bedford Basin, a completely land-locked sheet of water. This grand sea-lake has an area of ten square miles, and is capable of containing any number of navies. Halifax possesses another advantage not common to every harbour of North America: it is accessible at all seasons, and navigation is rarely impeded by ice. There are two fine lighthouses at Halifax; that on an island off Sambro Head is 210 feet high. The port possesses many large ships of its own, generally employed in the South Sea whale and seal fishery. It is a very prosperous fishing town in other respects.
