It is by no means to be presumed as certain that the early navigators chose the Straits of Dover as the readiest passage to the new world they were to people. Both Welsh and Danish traditions point to a migration from Jutland. Whencesoever the first emigrants came, Providence alone could pilot their frail barks. Successive migrations, the chances of shipwreck, or the like independent causes, may have landed the fathers of the British race on widely different parts of our island coast. It is a well established fact, that at later periods many distinct and rival centres of population were thus established throughout the British Isle. Lochar Moss, a well-known tract in Dumfriesshire, occupies an area of fully twelve miles in length, by between two and three miles in breadth, extending to the Solway Frith. Its history is summed up in an old popular rhyme, still repeated in the surrounding districts:-- "First a wood, and next a sea, Now a moss, and ever will be!" Lying as it does on the southern outskirts of the Scottish kingdom, the track of many successive generations has lain along its margin or across its treacherous surface, beneath which their records have been from time to time engulfed, to be restored in after ages to the light of day. To these we shall have occasion again to refer; but among them our chief attention is meanwhile attracted by its ancient canoes, repeatedly found along with huge trunks of trees, hazel-nuts, acorns, and other traces of the forest, and also, according to the old statist of Torthorwald parish, "anchors, cables, and oars," the no less obvious heirlooms of the sea. During the last century the peats cut from this moss formed almost the sole supply of fuel to the inhabitants of Dumfries and its neighbourhood, nor have they yet ceased to avail themselves of its ready stores.
