With glowing heart and island lyre, Ah! would some native bard arise To sing, with all a poet’s fire, Thy stern sublimities— The roaring flood, the rushing stream, The promontory wild and bare, The pyramid where sea-birds scream Aloft in middle air, The Druid temple on the heath, Old even beyond tradition’s breath. If we allow a little for the softer side of the picture, a side perhaps best typified by the fine old buildings of the little island capital, and the spell of the lightful midsummer night, which is no night, the lines of Vedder form a fair compendium of the natural conditions and general characteristics of the Islands to-day, although much of the “bleak and treeless moor” of the poet’s youth has long since been converted into smiling fields of corn. 3. Size. Situation. Boundaries The Orkney Islands extend between the parallels 58° 41´ and 59° 24´ of north latitude, and 2° 22´ and 3° 26´ of west longitude. They measure 56 miles from north-east to south-west, and 29 miles from east to west, and cover 240,476 acres or 375.5 square miles, exclusive of fresh water lochs. The group is bounded by the North Sea and the Pentland Firth on the south, the Atlantic on the west, Sumburgh Roost on the north, and the North Sea on the east. Our measurements take no account of the distant Sule Skerry, an islet of 35 acres lying 32½ miles north-west of Hoy Head, and inhabited only by lightkeepers and innumerable birds. The archipelago is naturally divided into three sections: the Mainland in the centre, the South Isles including all islands to the south, and the North Isles all to the north, of the Mainland. The Mainland—the Norse _Meginland_, or _Hrossey_, _i.e._ Horse Island—covers 190 square miles, and is 25 miles long from north-west to south-east, and 15 miles broad from east to west. It is divided into two unequal portions, the East Mainland and the West Mainland, by an isthmus less than two miles across, which connects Kirkwall Bay on its north sea-board with Scapa Flow, a large and picturesque inland sea, now well known as a naval base, which lies between its south coasts and the encircling South Isles. The name Pomona, stamped on the Mainland by George Buchanan’s misapprehension of a Latin text, is never applied to the island by Orcadians; and here be it also said that Hoy and Walls, the largest of the South Isles and the second in size of the whole group (13½ miles long by about 5½ miles broad, and covering 36,674 acres), although one island geographically, is colloquially two. The principal of the other South Isles are South Ronaldshay, 13,080 acres; Burray, 2682 acres; Flotta, 2661 acres; Graemsay, 1151 acres; and Fara, 840 acres. Scapa Flow is connected with the Pentland Firth to the south by Hoxa Sound, with the Atlantic to the west by Hoy Sound, and with the North Sea to the east by Holm Sound. The largest of the North Isles are Sanday,
