Mount Edgcumbe is in Cornwall; but until recently it was a part of Devonshire; the Act of Parliament that removed it from one county to the other dating no further back than 1854. But Acts of Parliament have done other wonders in this district, for it was only in 1824 that an act was passed giving to the town of “Plymouth Dock,”—or, as it was then generally called, “Dock,”—the new and more pretentious name which it now holds of _Devonport_. The “Mount” is about half a mile across the bay which divides it from the now “united” towns of Devonport, Stonehouse, and Plymouth, which, together, contain a population of 150,000 “souls.” From any of the adjacent heights, especially the Hoe at Plymouth, we obtain a glorious view of the road-stead—fortified everywhere. In mid-distance is seen the Breakwater, one of the marvels of engineering art; and far off, yet within view, the famous lighthouse—the Eddystone, some fourteen miles from the nearest shore. Between these objects and the port are, at all times, many ships of the navy: they rule the waves of ocean in the seas that encircle earth; and Plymouth will be especially glorified when the triumphs of British sailors, from the admiral to the able seaman, supply subjects of discourse. The Breakwater, one of the most gigantic works in the kingdom, lies in Plymouth Sound, where it forms a line between Bovisand Bay on the east, and Cawsand Bay on the west. It is about three miles from Plymouth, and is a mile in length. In form it is a straight line, with a kant or arm at each end, branching off towards the shore. At its eastern end a clear passage between it and the Bovisand shore of about a mile in width is left for ships, while at the western end the passage is about a mile and a half in width. The idea of the Breakwater originated with Earl St. Vincent in 1806, and Mr. Rennie and Mr. Whidbey surveyed the Sound for the purpose. In 1811 the plan was decided upon. The first stone was deposited on the birthday of the Prince Regent (afterwards George IV.), 1812. In 1817, and again in 1824, much damage was done to the progressing work. The quantity of stone used in its formation is estimated at about four millions of tons, exclusive of about two millions and a half of tons of granite and other stones used for paving, facings, &c. At the east end is a beacon, and at the west end a lighthouse 60 feet high. The spirited engraving of this gigantic undertaking, which we here give, is taken from Mr. Jewitt’s recently published “History of Plymouth,” where it forms one of many illustrations. The view, as will be seen, is a kind of bird’s-eye, and shows the form of the Breakwater, with its new central fort and its lighthouse and beacon. [Illustration: _Plymouth Breakwater._]
