As, wherever the country was populated, interments of the dead must, as a necessity, have taken place, these all-important store-houses of after-knowledge exist, or have existed, to more or less extent in almost every district throughout the land, and give evidence, whenever opened by experienced hands, of their historical value and importance. The earliest grave-mounds are mostly found in the mountainous districts of the land--among the hills and fastnesses; the latter overspreading hill and valley and plain alike. Thus, in Cornwall and Yorkshire, in Derbyshire and in Dorsetshire, in Wiltshire and in many other districts, the earliest interments are, or have been, abundant; while the later ones, besides being mixed up with them in the districts named, are spread over every other county. In the counties just named Celtic remains abound more than those of any other period. In Dorsetshire, for instance, that county, as the venerable Stukeley declares, “for sight of barrows not to be equalled in the world,” the early mounds abound on the downs and on the lofty Ridgeway, an immense range of hills of some forty miles in extent, while those of a later period lie in other parts of the county. In Yorkshire, again, they abound chiefly in the wolds; and in Cornwall, on the high lands. The same, again, of Derbyshire, where they lie for the most part scattered over the wild, mountainous, and beautiful district known as the High Peak--a district occupying nearly one half of the county, and containing within its limits many towns, villages, and other places of extreme interest. In this it resembles Dorsetshire; for in the district comprised in the Ridgeway and the downs are very many highly interesting and important places, around which the tumuli are most plentiful. It is true that here and there in Derbyshire, as in other counties, an early grave-mound exists in the southern or lowland portion of the county; but, as a rule, they may be almost said to be peculiar, and confined, to the northern, or hilly district, where in some parts they are very abundant. Indeed, there are districts where there is scarcely a hill, even in that land, where “Hills upon hills, Mountains on mountains rise,” where a barrow does not exist or is not known to have existed. In passing along the old high-road, for instance, over Middleton Moor by way of Arbor Low,[1] Parcelly Hay, High Needham, Earl Sterndale, and Brier Low, to Buxton, or along the high-roads by way of Winster, Hartington, or Newhaven, the practised eye has no difficulty in resting on the forms of grave-mounds on the summits of the different hills or mountains, whose outlines stand out clear and distinct against the sky.
