In the front of this view, and towards the right, a man-of-war cutter is seen running out of the harbour; and, from her heel to leeward, and the agitated state of the water, we may perceive that it is blowing a stiff breeze. Vessels of her class are chiefly employed in the coast-guard service and as admirals' tenders, or as packets on short voyages, or in communicating between one naval depôt and another. In the distance, to leeward of her, the Dock-yard semaphore is perceived; and more to the right, but nearer to the eye of the spectator, is seen the Round Tower; from which, in former times, an immense chain used to extend to the Block-house at Gosport, on the opposite side of the channel, for the purpose of protecting the entrance to the harbour, in the event of its being assailed by the ships of an enemy. Towards the centre of the engraving a broad-side view is presented of the Port-Admiral's flag-ship, a first-rate, which, from the flags at her mast-head, appears to be making a signal; ahead of her, in the distance, the hulls are perceived of two ships of war, laid up in ordinary; and further to the left is seen part of the Block-house Fort, at Gosport, with a beacon, to direct vessels in making the harbour. Portsmouth harbour is one of the most secure and commodious in the kingdom; and from the depth of water, both within it and at its mouth, ships of the line can enter or depart at all times of the tide. From the narrowness of its entrance,--which, between the old Round Tower at Portsmouth and the Block-house Fort at Gosport, is not wider than the Thames at London-bridge,--it is protected from the swell of the sea; while it is sheltered from the violence of winds blowing off the land, by the range of hills to the northward. Immediately above its entrance the harbour begins to expand, and about a mile and a half above the old Round Tower it is nearly two miles in breadth. It then branches off into three principal creeks, or _leats_, as they are frequently called; one of which runs up to Fareham, another to Porchester Castle, and the third to Portsbridge. In these creeks most of the men-of-war in ordinary are moored. As those ships, when laid up, are each covered over with a large wooden roof, to protect them from the effects of the weather, they appear, when seen from Portsdown Hill, which commands an excellent view of the harbour, not so much like floating castles as like immense floating barns--ample garners, which would contain more corn than the swords and cutlasses of their former gallant crews, beat into reaping-hooks, will ever cut down!
