We heard sermon in the open air with a poor Highland congregation in Sutherlandshire only a few weeks ago; and the scene was one which we shall not soon forget. The place of meeting was a green hill-side, near the opening of a deep, long withdrawing strath, with a river running through the midst. We stood on the slope where the last of a line of bold eminences, that form the southern side of the valley, sinks towards the sea. A tall precipitous mountain, reverend and hoary, and well fitted to tranquillize the mind, from the sober solemnity that rests on its massy features, rose fronting us on the north; a quiet burial-ground lay at its feet; while, on the opposite side, between us and the sea, there frowned an ancient stronghold of time-eaten stone--an impressive memorial of an age of violence and bloodshed. The last proprietor, says tradition, had to quit this dwelling by night, with all his family, in consequence of some unfortunate broil, and take refuge in a small coasting vessel; a terrible storm arose--the vessel foundered at sea--and the hapless proprietor and his children were nevermore heard of. And hence, it is said, the extinction of the race. The story speaks of an unsettled time; nor is it difficult to trace, in the long deep valley on the opposite hand, the memorials of a story not less sad, though much more modern. On both sides the river the eye rests on a multitude of scattered patches of green, that seem inlaid in the brown heath. We trace on these islands of sward the marks of furrows, and mark here and there, through the loneliness, the remains of a group of cottages, well-nigh levelled with the soil, and, haply like those ruins which eastern conquerors leave in their track, still scathed with fire. All is solitude within the valley, except where, at wide intervals, the shieling of a shepherd may be seen; but at its opening, where the hills range to the coast, the cottages for miles together lie clustered as in a hamlet. From the north of Helmsdale to the south of Port Gower, the lower slopes of the hills are covered by a labyrinth of stone fences, minute patches of corn, and endless cottages. It would seem as if for twenty miles the long withdrawing valley had been swept of its inhabitants, and the accumulated sweepings left at its mouth, just as we see the sweepings of a room sometimes left at the door. And such generally is the present state of Sutherland. The interior is a solitude occupied by a few sheep-farmers and their hinds; while a more numerous population than fell to the share of the entire county, ere the inhabitants were expelled from their inland holdings, and left to squat upon the coast, occupy the selvage of discontent and poverty that fringes its shores. The congregation with which we worshipped on this occasion was drawn mainly from these cottages, and the neighbouring village of Helmsdale. It consisted of from six to eight hundred Highlanders, all devoted adherents of the Free Church.
