one of the Western Isles of Scotland, lying about two leagues to the southward of Harries. It is about five miles in circumference; the soil is sandy, but when manured with the alga marina, extremely fertile, fertile, producing an increase of thirty-fold of barley; may, one grain has been known to produce 14 ears when the season was remarkably favourable. The face of the island is extremely agreeable in summer, exhibiting a pleasing variety of corn fields and clover pastures. Here is a fresh-water lake called Lochbruis, diversified with small islands, and abounding with eels, which the natives by the help of lights catch in the night-time, as they fall down a rivulet towards the sea in heaps twitted together. There are two chapels in this island dedicated to St Asaph and St Columbus; and near the former is a stone standing about eight feet above the ground. At the east end of this island there is a strange reciprocation of the flux and reflux of the sea, and another no less remarkable upon the west side of the Long island. The tides from the south-west run along northward; so that during the ordinary course of the tides the flood runs east in the frith where Bernera lies, and the ebb runs west: thus the sea ebbs and flows regularly for four days before, and as long after, the full and change of the moon; the spring tides generally rising 14 feet perpendicular, and the others proportionably: but for four days before, and as many after, the quarter moons, there is a singular variation; at that time a southerly moon making high water, the course of the tide being eastward, it begins to flow at half an hour after nine in the morning, and continues to flow till half an hour after three in the afternoon, when it is high water; but when it begins to ebb, the current still runs eastward, until it is low water; so that the tide runs eastward 12 hours together, that is, from half past nine in the morning till half past nine at night; yet when the night-tide begins to flow, the current turns and runs westward all night for 12 hours, during both flood and ebb: thus the reciprocations continue, one flood and ebb running eastward and another westward, till within four days of the full and change of the moon; then they resume their ordinary course, running east during the six hours of flood, and west during the six hours of ebb. There is another phenomenon in these tides no less remarkable than that just now mentioned. Between the vernal and autumnal equinox, that is, during one half of the year, the tides about the quarter moons run all day eastward and all night westward; and during the other six months their course is reversed, being westward in the day and eastward in the night.
